In Maymembers of the EEC and 81 other nations that had signed the Montreal Protocol decided at a meeting in Helsinki, Finland, to try to achieve a total phase-out of CFCs by the yearas well as phase-outs as soon as possible of other ozone-damaging chemicals like carbon tetrachloride, halons, and methyl chloroform.

Long-lived greenhouse gaseswhich trap heat in the atmosphere, include carbon dioxide, methane, nitrous oxide, and fluorinated gases. During the daytime when heating occurs, the air in the valley is warmed and rises, permitting the pollutants to escape.

The Antarctic ozone hole The most dramatic evidence of the destruction of the ozone layer has occurred over Antarctica, where The problems caused by air pollution massive "hole" in the ozone layer appears each winter and spring, apparently exacerbated by the area's unique and violent climatological conditions.

Air pollution is no new phenomenon. However, the report did acknowledge that environmental regulations and industrial reforms had had some effect. Ammonia NH3 — emitted from agricultural processes. These VOCs react with primary anthropogenic pollutants—specifically, NOx, SO2, and anthropogenic organic carbon compounds — to produce a seasonal haze of secondary pollutants.

Chlorofluorocarbons CFCs — harmful to the ozone layer ; emitted from products are currently banned from use. Some of the data that has been gathered is alarming.

Under these conditions, the atmosphere inhibits the upward spread of pollutants. Other harmful pollutants emitted in by the US coal power fleet include: When fossil fuels are burned, they let out oxides into the air.
