VEHICLE POLLUTION AND EFFECTS
With the ongoing advancement of technology and industrialization, human beings are enjoying more and more amenities and comforts. In parallel, environmental damage has also occurred by over-use of technology. One of the major achievements of modern technology is automobile which has made great contributions to the development of modern society because of their affordability. Owing to their sharp growth, vehicles are emerging as the largest source of urban pollution in the developing world. Vehicles emit pollutant gases such as hydrocarbons(HC), carbon-dioxide (CO2), carbon monoxide(CO), volatile organic compounds(VOC), nitrogen oxide(NOx), Sulfur dioxide (SO2), and particulate matter(PM) which are causes of global warming, smog, greenhouse effects and acid rain. Increased automobiles simply mean increased air, noise pollution and escalated number of accidents. This essay will discuss vehicle pollution effects and evaluate a various effective solution to mitigate the adverse impacts of motor vehicle use.
In the last few decades, Automobile sector has been growing sharply and we are mostly using two main fuel types of vehicles petrol and diesel which are flammable and toxic. The internal combustion of diesel and petrol fuel in engines emit unfavorable substances. Carbon-monoxide(CO) outcomes from the incomplete combustion which is harmful to human and animal beings that breathe it. Carbon-monoxide(CO) diminish the efficiency of oxygen-carrying capacity Pollutant gases produce from the huge number of motor-vehicle add to a remarkable pollution.
Technical and economic measures to discourage the use of private vehicles and encourage the use of public transport modes are essential for reducing traffic congestion and controlling urban sprawl. Appropriate design of roads, intersections and traffic control systems can eliminate bottlenecks, accommodate public transport and smooth traffic flow at the moderate cost which helps to diminish urban air pollution and improve traffic safety.
Motor vehicle emission can be controlled most effectively by designing vehicles to have low emissions from the beginning. Advanced emission controls can reduce hydro-carbon and carbon-monoxide emissions by more than 95% and emissions of nitrogen oxides by 80%
Stopping the growth in motor vehicle use is neither feasible nor desirable, given the economic and other benefits of increased mobility. The challenge then is to manage the growth of motorized transport so as to maximize its benefits while minimizing its adverse impacts on the environment and on society. Such a management strategy will generally require economic and technical measures to limit environmental impacts, together with public and private investments in vehicles and transport infrastructure.
