| Date: | September 2000 |
| Description: | Air pollution, both indoors and outdoors, is a major environmental health problem affecting developed and developing counties alike. It comes from sources of dust, gases and smoke, and is generated mainly by human activities but also naturally. When inhaled, air pollutants affect the lung and respiratory tract but can also be taken up and transported by the blood stream throughout the body. Through deposition in the environment, air pollutants can also contaminate food and water.
