PCBs are mainly broken down either by the effect (direct or indirect) of sunlight or by microorganisms. In general, the persistence of PCB congeners increases with the number of chlorine atoms. Sunlight can play a role in the breakdown of PCBs present in air, water and surface soil. In the atmosphere, PCBs that are present in the atmosphere tend to react with ozone and water under the effect of sunlight.
Bad Ozone-In the Earth s lower atmosphere, near ground level, ozone is formed when pollutants emitted by cars, power plants, industrial boilers, refineries, chemical plants, and other sources react chemically in the presence of sunlight.Ozone at ground level is a harmful pollutant. Ozone occurs naturally in the Earth s upper atmosphere (the stratosphere), where it shields the Earth from the sun s ultraviolet rays. 2  At ground-level, ozone is an air pollutant that can harm human health.
