Pollution and long-term effects on the human body


Parts of the body affected by various pollutants

POLLUTION AND LONG-TERM EFFECTS ON THE HUMAN BODY

Many different kinds of pollutants affect the human body unknowingly because the chronic (months to years of exposure to the pollutants) are not dramatic compared to the acute (few seconds to days exposure) menaces. The more pronounced acute symptoms are diarrhea, eye and skin irritation, cough and sneezing. Often, by the time clinical symptoms (months to years of exposure to the pollutants) emerge, permanent damage has already been done. Pollutants may also affect the unborn child of a pregnant mother. The effects may appear as abortion, stillbirth and congenital birth defects.

Some pollutants, its long-term effects and the specific organs affected are presented below.
