Automobile Pollution Essay

Exponential growth in petrol and diesel render vehicles are responsible for deterioration of air quality in cities. Because of the increment in urbanization, industrialization and commercial activities in the urban areas, the demand for expect has also been increased. In addition to it the use of personal vehicles has also increase steadily. The various principle pollutants emit from vehicles are as follows- Carbon monoxide (CO) hang particulate matter matter (SPM) Oxides of nitrogen (NOx) Hydrocarbons (HC) Polynuclear aromatic hydrocarbons (PAHs).2005 Air Toxic Emissions from On-road planetary Sources (Tox-weighted) Affects of Automobile Pollution 1. In India ab erupt 15-20 million people are asthmatic because of emission of motorcar pollution. 2. N02 is a highly toxic natural gas and attacks the lungs causing lung cancer and emphysema. 3. Automobile pollutants interferes the development and functioning of the nervous system. 4. rough diseases such as bronchitis, plurosis occur by long-term exposure to the particulate matter. 5. N02 reacts with hydrocarbons and creates photochemical smog.Reasons for Automobile Pollution The petrol operate vehicles emit camouflaged gases such as CO and Benzene while diesel driven vehicles emit brinyly black smog containing minute carbon particles and S02. The main reasons for vehicular pollution problems are as follows- 1. Poor quality of burn down 2. Outdated vehicles 3. Congestion and mixed traffic of different types 4. Lack of prudish traffic management Important Pre-requisites for Controlling Vehicular Pollution 1. Phasing out of grossly polluted vehicles 2. Enforcement of emission norms for new and in-use vehicles.3. Improvement in automobile technology 4. Reduction of lead content in motor dismiss 5. Stream lining traffic management 6. Improvement in ordinary transport system 7. Fuel quality improvement and switch over to cleaner sack 8. Restriction on indiscriminate growth of urban centers, industrial a nd commercial activities Alternative Fuels Hydrogen Gas It can be utilise in modified combustion engines and is eco-friendly as it emits water vapours only. Electric Vehicles They are advantageous over conventional fueled vehicles as far as environment is concerned.Ethanol It can be used in regular automobiles after blending with petrol. It is rather clean fuel with low nitrogen oxide and hydrocarbons emission and no net C02 emission. Methanol It is a liquid fuel and is produce from coal, natural gas and biomass. ft emits real little NOx and HC. Natural gas It exists in the gaseous severalize at normal temperature and pressure and is found in the form of CNG and LPG. It causes comfortably lower pollution without affecting the performance of the vehicles.
