Since the early 1980s, the core mission of hei is to study the health effects of air pollution with a focus on vehicular emissions more recently, the scope has broadened to air pollution in general, because ultimately people are exposed to a mixture of pollutants from different sources. Air pollution is caused when air in the atmosphere is filled with particulate matter the largest source air of pollution in cities is from vehicle exhaust fumes carbon monoxide is the largest air pollutant in the united states, and it’s number one source is from vehicle exhausts. Pollution is the introduction of contaminants into the natural environment that cause adverse change pollution can take the form of chemical substances or energy, such as noise, heat or light pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminantspollution is often classed as point source or nonpoint source pollution.

Air pollution is a major concern of new civilized world, which has a serious toxicological impact on human health and the environment it has a number of different emission sources, but motor vehicles and industrial processes contribute the major part of air pollution. Sporadic air pollution events, like the historic london fog in 1952 and a number of short and long term epidemiological studies investigated the effects of air quality changes on human health a constant finding is that air pollutants contribute to increased mortality and hospital admissions ( brunekreef and holgate, 2002 . Air pollution causes acid rain, reduces visibility, damages wildlife, contributes to eutrophication and depletion of the ozone layer in addition, air pollution leads to global warming hence resulting in global climate change the burning of fossil fuels releases oxides of nitrogen and sulfur into. Effects on the ecosystem: in short, environmental pollution, almost exclusively created by human activities, has a negative effect on the ecosystem, destroying crucial layers of it and causing an even more negative effect on the upper layers.
