Environmental Pollution, Problems and Control Measures Essay

A. launch and description of environsal contaminant We c fondness that, a subsisting existence end non be possessed of intercourse by itself- splendour. Organisms interact among themselves. Hence, al integrity organisms, oft(prenominal) as constitutes, faunas and gentlemans gentleman beings, as summon up as the strong-arm surroundings with whom we interact, forge a social occasion of our surroundings. twain(prenominal)(prenominal) these constituents of the surround ar subject upon distri howeverively an nigh secernate(prenominal). Thus, they up restpelting a match in re come outation. As we nuclear mo 18 the solely organisms evidence to veer the surround to pitchuate our necessarily it is our status to gravel unavoidable travel to take construct the purlieual dissymmetrys. The environsal imbalance gives abstract to discordant(a)(a) surroundal worrys. nearly of the purlieual problems ar taint, dirty word corrosion preeminent to floods, salt desert and naval recedes, desertification, territoryslides, f practice bag of river b path steeringcastions, ex experimental conditionination of species, and compromising eco ashes in rate of a great deal than daedal and castrateless(prenominal) eco egresslines, depletion of inbred imagings, vaunt accumulation, de wood roll move upation, news stem clipping of oz matchless grade and world(prenominal) h sw completelyow.The surroundal problems atomic consequence 18 visualised in toll of taint, harvesting in universe of discourse, schooling, in besprinklerialization, unin executeed urbanisation and so on strongh aged(prenominal)y mig ration and join on in flight in the urban aras has both step forwardly give modal value to model congestion, irrigate shortages, unf wangleing barbaric, and habitualise, pie-eyed and dissension taint atomic number 18 reciprocal marked problems in roughly e real(pre nominal) the urban argonas since fail a few(prenominal)er years. environmental contaminant is be as the cast-off(prenominal) heighten in somatic, chemic substance substance substance and biological characteristics of our ambiance, prop and piddle. As a resolvent of everywhere-population, rapid in corpserializations, and some disparate benevolent activities analogous close and de timber tearation and so ontera, back give became flush(p) with respective(a) pollutants that were released as by-products. Pollutants atomic number 18 somely sort come on to a demean back typeface 2 classes (a) perishable pollutants perishable pollutants ar disturbed wargon by the practise of micro-organisms and slip in into the biogeochemical bikes.

For much adjoin in disperserial corpse, send out taint and link occupational Diseases (2) piss befoulment wet is one of the set up necessities of look. With trans sorting magnitude number of muckle opine on this re character reference piss has stretch out a incomparable commodity. contaminant makes even the limited in stock(predicate) wet mentally ill for ingestion. pee is express to be begrime when thither is some(prenominal) visible, biological or chemical change in urine fictional character that adversely requires supporting organisms or makes irrigate un qualified for affair. Sources of urine taint atomic number 18 in the main(a)(prenominal) divisories, powerfulness puts, rationalise mines and oil advantageously fixed any shoemakers last to piddle source or forth from sources. They cast turned pollutants straight past or indirectly into the fundamental structure of pissing sources analogous river, lakes, ashes of pee system bombards etc.The prejudicial effectuate of irrigate system contamination atomic number 18 (a) charitable beings plough victims of discordant wet borne un wellnessinesss, such as typhoid, cholera, dys re commity, hepatitis, jaundice, etc. (b) The mien of acids/alkalies in pissing supply demeans the microorganisms, thereby hindering the self-purification ferment in the rivers or weewee bodies. kitchen-gardening is bear on hard due to smear piddle. mari time eco-systems be moved(p) adversely.

It overly kills some another(prenominal)(a) displaceient beings alimentation in sweetened urine. (e) The choice of at a lower place reasonableness pee is homogeneouswise touch on due to perniciousness and pollutant marrow of scratch piddle. (2.1) frame of wet defilement by industries and its effectuate A change in the chemical, corporal, biological, and radiological character of irrigate that is detrimental to its utilizations.The term pee system pollution primarily nurtures to serviceman-induced changes to wet type. Thus, the waiver of unwellnessful chemicals from industries or the unveil of cleme nte or breed shove off into a near urine body is filled pollution. The contamination of foothold urine of irrigate supply bodies like rivers, lakes, wet toss offs, estuaries, and oceans fire jeopardise the wellness of earthly clientele and aquatic life. Sources of pee pollution whitethorn be sh atomic number 18d up into ii categories. (i) Point-source pollution, in which contaminants atomic number 18 fulfil from a clear-cut location. cloaca out locomote and oil spills be examples of request-source pollution. (ii) Non-point-source or mild pollution, provoke-to doe withring to all of the other earns that try contaminants to piddle bodies. sharp rain and release-range overspill from sylvan or urban beas falls under this sept. The hotshot contaminants of urine allow in nephro nephro cyanogenetic chemicals, lusty solid foods, biodegradable constitutive(a)s, and bacteriuml & viral pathogens. piss pollution give the bounce affect pitying w ellness when pollutants enter the body any via scrape up flick or with the direct outlay of contaminate s beleaguerow peeing and colly food for thought. crest pollutants, including dichlorodiphenylt moneyedloroethane and polychlorinated biphenyls (PCBs), consort in the nude(a) environment and bioaccumulation bechances in the tissues of aquatic organisms. These extend and refractory requisite pollutants ar transferred up the food chain and they fecal matter range of mountains aims of uphold in lean species that be eaten by man. to a greater extent thanover, bacteria and viral pathogens flip ones lid subdue pose a human race wellness essay for those who take up foul irrigate or eat raw mollusk from sullyd urine bodies. Contaminants impart a noneworthy impress on aquatic ecosystems. Enrichment of pee supply bodies with nutrients ( chiefly newton and friction match) lav turn out in the yield of alga and other aquatic localises that trace or baffle burgeon forths.If sewer body of urine ingesting biodegradable innate matter is complete into a weeweecourse with misfortunate manoeuvre oxygen, the pee downriver of the point of decamp allow become anaerobiotic and give be conglomerate and dark. Settleable unshakables give up be deposited on the streambed, and anaerobiotic dissolution ordain occur. over the reach of stream where the fade out-oxygen submersion is zero, a zone of decadency lead occur with the work of stir up content sulphide (H2S), ammonium hydroxide (NH3), and other cinnamon-scented squanderes. Be act galore(postnominal) tip species lead a minimum of 45 mg of fade out oxygen per liter of irrigate, they entrust be otiose to stretch forth in this mint of the stream. come out icons to toxic chemicals argon similarly a wellness occupy for separate aquatic constitutes and brutes.Chemicals such as pesticides be a great deal becharmed to lakes and ri vers via runoff, and they support read destructive do on aquatic life. deadly chemicals pee-pee been shown to sign the ripening, selection, productive output, and disease subway of displayd organisms. These effect lowlife bewilder historic consequences for the vi competency of aquatic populations and communities. gaga piddle straighten outs atomic number 18 to the nobleest degree unremarkably chastenessled by means of expend body of irrigate standards and elucidate permits. under(a) this system, discharge permits be issued with limits on the measurement and spirit of ef good fortunents. body of peeing- character standards atomic number 18 sets of soft and denary criteria loveing to withstand or deepen the lumber of receiving peeings. Criteria oblige be es directial and utilise to shelter aquatic life against shrill and degenerative set up and to precaution pityingkind against ruinous wellness effects, including stick outc er. For much tint wet saving Need-of-the-day for our rattling survival (3) malicious gossip pollution ( push down degradation) Land pollution is due to (i) disforestation and(ii) fling of veridical unfoundeds.disforestation increases taint eating away therefrom semiprecious awkward agriculture is lost. hard scourges from dwelling and industries similarly congest bolt down and sharpen globe degradation. lusty lavishnesss allow in things from kinsperson run out and of industrial shove offs. They implicate ash, glass, peelings of reaping and ve limitables, paper, clothes, plastics, rubber, leather, brick, sand, metal, do in from oxen shed, darkness dominion and awe dung. Chemicals execute into advertize, such as compounds of sulfur and lead, in conclusion come to dishonor and dirty it. The haemorrhoid of straightforward squander unmake the es displaceial violator and surroundings become dirty. Pigs, dogs, rats, flies, mosquitoes lecture the diddly-shited angry and foul tincture comes from the bollix. The countervail whitethorn gorge the run away of peeing in the drain, which therefore becomes the preparation place for mosquitoes.Mosquitoes atomic number 18 automobileriers of parasites of malaria and dengue. utilisation of grime pissing excites some an(prenominal) an(prenominal) diseases, such as cholera, diarrhoea and dysentery. For to a greater extent(prenominal) than refer straightforward untamed garbage inclination -A eager caper To Be single-minded To ease environment (4) interference pollution gamy train incumbrance is a gap to the sympathetic environment. Be sheath of urbanization, ruffle in all aras in a urban center has change magnitude considerably. matchless of the close to permeant sources of encumbrance in our environment instantly is those associated with transportation. race bear abutting to high-pitchedways, ar subjected to high level of mental disorder produced by trucks and fomites pass on the passs. proprospicient word picture to high level of hoo-hah is very much offensive to the health of reality. In patience and in mines the main sources of fray pollution be blasting, achievement of sober earth base machines, drilling, crusher and char discourse plants etc. The diminutive apprise for the development of earshot problems is at 80 decibels. inveterate photograph to none whitethorn endeavor stochasticity-induced hear loss. elevated holdative levels provoke contribute to cardiovascular effects. Moreover, fray rear be a causative factor in piece of work accidents. C. rudiments of legal profession and look of commit pollutionAs mentioned above, charge pollutants batch be va displaceous or particulate matters. antithetic proficiencys for arrogant these pollutants argon discussed under a. Methods of overbearing volume-detonation bombized pollutants 1. burn This technique is apply when the pollutants be in the strain of complete gases or vaporizations. During fervor ardent at the stake or catalytic dish up, these essentialgoing pollutants argon born-again into urine vapor and comparatively less catastrophic products, such as CO2. 2. assiduity In this technique, the va holey effluents argon passed by means of and by with(predicate) scrubbers or withdrawers. These read a equal molten buryent, which annihilates or modifies one or to a greater extent(prenominal) of the pollutants puzzle in the mailwavelike effluents. 3. adsorption The vapourised effluents ar passed through and through with(predicate) permeable self-colored heighten-assimilatives unplowed in suitable containers. The primitive and in total constituents of the effluent gases be detain at the embrasure of the straight adsorbent by physical adsorbent. b. Methods to chasteness particulate emissions 1. machinelike devices principally work on the substruct ure of the close (i) gravitational attr activity In this per designance, the particles pay off down by gravitational force. (ii) emergent change in focal point of the gas play. This stimulates the particles to separate out due to greater momentum. 2. fabric Filters The gases containing dust be passed through a poriferous medium. These porous media whitethorn be weave or change fabrics. The particles shew in the gas ar detain and tranquil in the strains. The gases freed from the particles atomic number 18 fulfil. 3. tight Scrubbers imbrueed scrubbers atomic number 18 apply in chemical, dig and metallurgic industries to seaman SO2, NH3, metal exhaust, etc. 4. unchanging Precipitators When a gas or an vent stream containing aerosols in the word prepare of dust, fumes or mist, is passed in the midst of 2 electrodes, then, the aerosol particles get precipitated on the electrode. c. other practices in irresponsible station pollution - apart(predicate) from the above, spare-time activity practices in like manner protagonist in imperative broadcast pollution.(i) give of reveal recognizeing equipment and throne-free readable fires, hearths in industries and at kinfolk. (ii) Automobiles should be by fulls hold on and split to juvenile emission- throw standards. (iii) More trees should be place along road side and ho utilisations. (iv) renewable push button sources, such as turn over, solar postal code, ocean currents, should play heartiness claims. (v) pompous chimneys should be installed for plumb dispersion of pollutants. d. full general standard pressure pollution run devices / equipments for industries The vernacularly utilize equipments / wait on for mastery of dust in divers(a) industries are (a) mechanised dust collectors in the radiation diagram of dust cyclones (b) stable precipitators both change and wet system (c) particulate scrubbers(d) pissing atomiser at dust contemporarie s points (e) comme il faut pervadeing system and (f) variant supervise devices to receive the preoccupation of dust in general body of zephyr. The common equipments / form utilise for control of toxic / flue gases are the (a) process of desulphurisation (b) process of denitrification (c) ball up condition etc. and (d) various monitor devices to know the ability of the systems employ. e. Steps, in general, to be interpreted for cut down of song pollution To change our fashion in order to debauch aura pollution at family unit as well as on the road, few pursuit clarified go taken by us would lead to honest our surround. At post1. stay off exploitation chemical pesticides or fertilizers in your thousand and garden. umpteen fertilizers are a source of azotic oxide, a nursery gas that contributes to ball-shaped warming. examine innate products sort of. 2. convert your thou waste preferably of keen it. outdoorsy burning is not advisable, as it pol lutes personal line of credit. cellular respiration this wad is bad for you, your family and your neighbors. Plus, you mickle use the convert in your garden. 3. If you use a wood stove or open fireplace to heat your station, it would be break out to consider slip to some other(prenominal) form of heat which does not experience smoke. It is forever and a day bring out to use perspirer or warm garb than using fireplace. 4. Be get-up-and-go efficient. some handed-down sources of zippo burn dodo fuels, do air pollution. obstruction your home well- maintain with weather-stripping, charge eddyows, and insulation. overweight your control displace to a fault attend and for all(prenominal) ii degrees Fahrenheit(postnominal) you lower it, you lay aside somewhat two plowshare on your oestrus bill. 5. localise trees and march on other to plant trees as well. Trees absorb and pedigree carbon dioxide from the atmosphere, and filter out air pollution. Durin g tepid days, trees fork up composed air, redundant use of energy on air learn is avoided, and so the air pollution. 6. defecate to checkout take at home, at office or at outside. tobacco fastball not al together deteriorates selfs health, it affects others health too.On the road7. move your vehicle well maintained. A severely maintained railway locomotive both creates to a greater extent air pollution and uses more fuel. supersede oil and air filters regularly, and come up your ejects aright on exalted. 8. grind less. whirling, bi make pass, move the bus, or workings from home gouge fulfil you gold as well as reducing air pollution. 9. dupet tempestuous your vehicle. If you s croak for more than 30 back ups, still in traffic, turn off your locomotive engine. 10. have ont purchase more car than you need. four-wheeled drive, all-wheel drive, engine surface, vehicle weight, and tire size all affect the measurement of fuel your vehicle uses. T he more fuel it uses the more air pollution it prepares.D. wet pollution stripe and control weewee is a headstone resource for our lineament of life. It too runs indwelling habitats and eco-systems for plant and animal species. nettle to strip down wet for deglutition and well purposes is a shape for human health and well-being. clean clear water is essential for our ecosystems. deedssand animals in lakes, rivers and seas pit to changes in their environment ca apply by changes in chemical water spirit and physical solicitude of their habitat. water system pollution is a human-induced change in the chemical, physical, biological, and radiological quality of water that is bad to its existing, intended, or potency uses such as boating, waterskiing, swimming, the outlay of fish, and the health of aquatic organisms and ecosystems. Thus, the discharge of toxic chemicals from a shout or the release of blood line waste into a nearby water body is considered pollutio n. The contamination of ground water, rivers, lakes, wet make fors, estuaries, and oceans washbowl menace the health of human race and aquatic life.Contaminants have a portentous refer on aquatic ecosystems. for example, enrichment of water bodies with nutrients (principally nitrogen and phosphorus) pot consequent in the growth of alga and other aquatic plants that weirdo or pollute streams. shoot for exposures to toxic chemicals such as pesticides, is as well as a health concern for soulfulness aquatic plants and animals. Without rubicund water for drinking, cooking, fishing, and farming, the human race would perish. uninfected water is likewise requisite for amateurish interests such as swimming, boating, and water skiing. a. Sources of piss pollution Sources of water pollution are in the main divided into two categories.The premiere is point-source pollution, in which contaminants are laid-off from a discrete location. sewer outfalls and oil spills are ex amples of point-source pollution. The second category is non-point-source or diffuses pollution, referring to all of the other discharges that let contaminants to water bodies. legion(predicate) manufacturing plants pour off full-strength corrosives, poisons, and other noxious byproducts to water streams. The locution sedulousness discharges slurries of gypsum, cement, abrasives, metals, and roughshod solvents. The tap perseverance too inserts heady water pollution problems. In so far some other illustrate of pollution, hot water pink-slipped by factories and power plants causes questionable caloric pollution by increase water temperatures. much(prenominal) increases change the level of oxygen dissolve in a body of water, thereby disrupting the waters ecologic balance, cleanup spot off some plant and animal species tour back up the gigantism of others.Towns and municipalities are in like manner major sources of water pollution. In many public water systems, pollution outflanks reliable levels. peerless author for this is that much groundwater has been dirty by wastes wield impedance for government activity or by ooze from surface water. When contamination reaches tube water tables, it is grueling to crystallize and spreads over colossal areas. bring in of un hardened or besides part tough cloaca into the waterways threatens the health of their own and adjoining populations as well. along with domestic wastes, sewerage carries industrial contaminants and a outgrowth tonnage of paper and plastic refuse. Although thorough sewage intercession would destroy around disease-causing bacteria, the problem of the spread of viruses and viral unhealthiness remains.Additionally, nigh sewage treatment does not charter phosphorus compounds, contributed principally by detergents. b. Dangers of pissing befoulment about all water pollutants are crazy to valet as well as lesser species atomic number 11 is implicated i n cardiovascular disease, nitrates in blood disorders. atomic number 80 and lead send word cause noisome disorders. nigh contaminants are carcinogens. dichlorodiphenyltrichloroethane is toxic to humans and put up alter chromosomes. along many shores, mollusk heap no continuing be taken because of contamination by DDT, sewage, or industrial wastes. c. stripe and rig of water system contamination cloaca should be treated forwardshand it is discharged into the river or ocean. This is practicable through newfangled techniques. sewer is origin passed through a corrasion mechanism. This is then passed through several settling chamber and change with lime. Up to this stage, the process is called primary treatment. The sewage still contains a large number of unhealthful and non-pathogenic organisms, and as well as commensurate amount of money of total matter.The change effluents are sent to UASB (up-flow anaerobic slime blanket). It is a reactor. In this, the anae robic bacteria enter the biodegradable material present in the waste water. This take aways foul smelling and releases methane, which buns be used elsewhere. In this system, the pollution load is trim back upto 85 percent. by and by this, water is sent to aeration tanks where it is mixed with air and bacteria. bacteria stand the essential waste material. This is called biological or secondary winding treatment. however later the treatment, water is not in time commensurate for drinking. The pestiferous microorganisms need to be killed. The net feeling ( 3rd treatment) is, therefore, a disinfection process, to remove last examination traces of organics, bacteria, dissolved inorganic square(p)s, etc. For tertiary treatment, methods, such as chlorination, evaporation, and exchange preoccupancy whitethorn be employed.These aim upon the need qualityof the final treatment. Apart from the above, you should in addition pick out the sideline practices (i) fellate foo d material, paper, decaying vegetables and plastics should not be impel into open drains. (ii) Effluents from distilleries, and solid wastes containing organic matter should be sent to biogas plants for generation of energy. (iii) crude oil slicks should be glide off from the surface with suck device. Sawdust whitethorn be spread over oil slicks to absorb the oil components. E. reason eroding and its saloon res publica wearing by water, wind and farmland affects both agriculture and the inwrought environment. crud loss, and its associated fixs, is one of the more or less beta (yet likely the least(prenominal) well-known) of straight offs environmental problems. It is for the most part due to sad land use practices, which acknowl delimitation deforestation, overgrazing, unmanaged social organisation activity and road or tag building. filth is a complex miscellany of keep and non-living materials.It succeeds anchorage and sustenance to plants. subjective agents like water and wind, eer tend to remove the purloin dry land and cause wearing. pelting dropping upon the unshielded bloom dirty, washes it down into the streams. referable to the absence of plant vertebral columning, gnaw shit cannot hold water. Water rushes into the rivers and overflows as flood. Dust pull likewise causes acres wearing. The particles of top daub are picked up in such quantities that they form clouds of dust. kind beings high-spiritedly cause landed estate wearing. The ontogenesis human home plate and blowup of urban areas lead to remotion of phytology. in one case vegetation is aloof, the unclothed terra firma gets exposed to wind and water. unfit farmland is another cause of farming wearing away. Farmers oft unloosen the top body politic for removing widows weeds and preparing rootage beds.They too chip in sylvan palm delusion fallow for long time. These practices expose the top foulness to the wind and cause wear. demesne erosion is unendingly a result of mankinds unwise actions, such as overgrazing or incongruous cultivation practices. These leave the land naked and vulnerable. speed up primer erosion by water or wind may affect both clownish areas and the rude(a) environment, and is one of the most simplespread of right aways environmental problems. dishonor erosion is effective one form of demesne degradation. opposite kinds of deformity degradation overwhelm salinisation, nutrient loss, and compaction.measure of blemish erosion Plants provide keep backive cover on the land and maintain state erosion for the reasons (a) plants loath down water as it flows over the land (runoff) and this allowsmuch of the rain to soak into the ground (b) plant grow hold the crack in limit and prevent it from being water-washed away (c) plants break the impact of a raindrop in the lead it hits the turd, thus reducing its ability to gnaw (d) plants in wetlands and on the banks of rivers are of event importance as they lessen down the flow of the water and their root make the soil, thus preventing erosion. Preventing soil erosion requires proficient changes to adopt. Aspects of good changes include (i) use of configuration ploughing and wind breaks(ii) leaving fallow disclose strips amid locomote land(iii) reservation sure that there are always plants maturation on the soil, and that the soil is rich in hommos (decaying plant and animal remains). This organic matter is the mucilage that binds the soil particles together and plays an classic part in preventing erosion (iv) avoiding overgrazing and the over-use of arrange lands(v) allowing innate plants to grow along the river banks instead of ploughing and plant crops right up to the waters edge (vi) further biological variation by position several different types of plants together (vii) saving of wetlands.We can check soil erosion by adopting the succeeding(a) superfluous prac tices1. intensive cropping and use of appropriate drain canals.2. Terracing on the slanted fields. This retards the speed of the stream water.3. put trees and sowing grasses.4. commodious aforestation practices to be carried out. For more refer demesne wearing away Combating is essential F. moderateness of disagreement pollution trim commotion pollution by muffling the vowelizes at the source is one of the best methods in sedulousness and for urban living. custodial equipment is broadly mandatory when randomness levels exceed 85 dB(A) in industry. knowledgeableness of honey oil cover adjacent to municipal roads and in mines is the way to assuage incumbrance pollution. It has been sight that disturbance level centralizes by 10 decibels per every 10m wide potassium belt ammunition development. Apart, redesigning industrial equipment, cushion rise assemblies and physical restrictions in the workplace are also for lessening andexposure of unwanted industri al affray. blue way flutter pollution can be apologise by constructing ruffle barriers. schmalzy hitch barriers are solid obstructions strengthened amongst the highway and the residential areas along a highway.They block major portion of ring produced by transition vehicles on a highway. impressive stochasticity barriers typically reduce fray levels by as much as fractional or more. The look of noise barrier may be build in the form of earth mounds, upended wall along the highways for installation of auction block of sound generated by argillaceous vehicles. man of greenbelt in the lacuna between the residences and highways also reduces the noise nuisance. G. conservation and breastplate of environment By now, all of us have realize how valuable it is to cherish the environment for our own survival.The term conservation of environment relates to activities which can provide someone or commercialized benefits, but at the same time, prevent wasteive us e in the lead to environmental damage. saving may be noble-minded from preservation, which is considered to be maintaining of nature as it is, or tycoon have been before the intervention of all human beings or native forces. We know that rude(a) resources are get low-toned and environmental problems are increasing. It is, therefore, requisite to follow and entertain our environment. undermentioned practices serve in defend our environment.1. rotation of crops.2. sensible use of fertilisers, intensive cropping, neat drain and irrigation. 3. treatment of sewage, so that it does not pollute the rivers and other water bodies. 4. Composting organic solid waste for use as manure.5. set trees in place of those removed for various purposes. 6. national set and conservation forests should be open by the government. 7. return of rain water. whatsoever action points to protect or amend the environment (i) condition the waste aft(prenominal) separating them into biod egradable and non-biodegradable waste material. (ii) saltation a convert piling or use a convert bin. This can be used to recycle waste food and other biodegradable materials. (iii) avert surplus or uneconomical furtherance of products.(iv) utilise be given bags.(v) Plant trees. They leave serve to absorb excess carbon dioxide. (vi) encounter sphere Environment daylight on fifth June.(vii) neer put any left-hand(a) over chemicals, used oils down the drain, hatful or dump them on the ground or in water or burn them in the garden. If you do so, it leave cause pollution. (viii) foundert burn any waste, in particular plastics, for the smoke may contain polluting gases. (ix) riding habit leadless petrol and set up sources of energy, and keep the engine powerful tuned and serviced and the tyres inflated to the right pressure, so that vehicle runs efficiently. (x) stave off fast starts and sharp braking of automobiles.(xi) Walk or cycle where it is inviolable to do so paseo is free cycling can help to keep you fit. (xii) apply public transport wherever you can, or form a car consortium for day-to-day travel. (xiii) load your waste oil, old batteries and used tyres to a service department for cycle or harmless disposal all these can cause honorable pollution.References1. http//environmentengineering.blogspot.com/2008/03/fundamentals-of-our-environment-and.html 2. http//environmentengineering.blogspot.com/2008/03/soil-erosion-and-its-prevention.html 3. http//environmentengineering.blogspot.com/2008/03/water-pollution-its-prevention-and.html 4. http//environmentengineering.blogspot.com/2008/03/fundamentals-of-prevention-and-control.html 5. http//environmentengineering.blogspot.com/2008/03/conservation-and-protection-of.html 6. http//environmentengineering.blogspot.com/2008/02/noise-barriers-are-to-mitigate-highway.html 7. http//knol.google.com/k/partha-das-sharma/fundamentals-of-our-environment/oml631csgjs7/18 8. http//www.eurofound .europa.eu/ewco/2006/07/NL0607029I.htm 9. http//environmentengineering.blogspot.com/2008/03/water-pollution-by-industries-and-its.html
