Among air pollutants let out by natural sources, only the radioactive gas radon is recognized as a major health threat. A by-product of the radioactive decay of uranium minerals in some kinds of rock, radon seeps into the basements of homes built on these rocks. According to recent estimates by the. Government, 20 percent of the homes in the. Have radon concentrations that are high enough to pose a risk of lung cancer. Lung cancer could cause deaths, and like i said before people dying is not good for the economy.
Each year countries that have many factories generate billions of tons of pollutants. The level is usually given in terms of atmospheric concentrations or, for gases in terms of parts per million, that is number of pollutant molecules per million air molecules. Lots come from directly identifiable sources like sulfur dioxide, for example, comes from electric power plants burning coal or oil. Others are formed through the action of sunlight on previously let out radioactive materials. For example, ozone, a dangerous pollutant in it is smog, smog is produced by the interaction of hydrocarbons and nitrogen oxides under the influence of sunlight. Ozone has also caused serious crop damage. On the other hand, the discovery in the 1980s that air pollutants like fluorocarbons are causing a hole in the ozone.
