noise pollution‚ gases and particulate emissions. It also contributes to climate change and global dimming. The toxic emissions produced by airports and aircraft are chiefly six pollutants: nitrogen oxides‚ volatile organic compounds‚ ground-level ozone‚ particulate matter‚ carbon monoxide‚ and sulphur dioxide (Whitelegg and Williams‚ 2000). These emissions have a definitive impact on the already growing problem of global warming as well as being very deadly to people exposed to them. In this study

some of which can cause problems for humans‚ plants‚ and animals. There are several main types of pollution and well-known effects of pollution which are commonly discussed. These include smog‚ acid rain‚ the greenhouse effect‚ and "holes" in the ozone layer. Each of these problems has serious implications for our health and well-being as well as for the whole environment. One type of air pollution is the release of particles into the air

Air pollution Air pollution affects everything from agriculture and ecosystems to human health‚ on a global scale. The five major air pollutants are ground-level ozone‚ particulate matter‚ carbon monoxide‚ sulfur dioxide‚ and nitrogen dioxide (Donnatelle‚ 2010). A majority of these pollutants are the result of human action. One example being coal power plants. These plants release greenhouse gas emissions and particle

The Governments contribution to regulate air pollution The United States Government has enacted many polices to help recognize the major causes of air pollution today and what people can do to help clean the air. People finally have the ability to understand more reasonable responses to environmental contaminants and they provide a window into the impacts that the human race is having on the earth. One of the main causes of air pollution is manufacturing due to particular matter and chemicals
