Document Summary
Bioaccumulative contaminants: polychlorinated biphenyls, mercury, ddt (banned in the us in 1975) Nitrogen oxides add this color to it. Sulfuric acid, nitric acid combined with condensation. Most of the acid rain is in the northeast obviously. Can do serious damage to plants, terrestrial effects. Table about aquatic, how much ph they can tolerate. Thinning in areas dependent on prevailing winds. Increase the rate of greenhouse warming, by reducing the effectiveness of the carbon dioxide sink in the oceans, uv lights kills phytoplankton. Most plants (and trees) grow more slowly and become more and more stunted as. Uv-b stimulates the formation of reactive radicals; more pollution adult plants when exposed to large amounts of uv-b. Doesn"t matter what type of air pollution, even a small amount of pollutant in the air you will have subclinical signs. Significant and lasting change in the statistical distribution of weather patterson. Mechanisms over periods ranging from decades to millions of years.
