Environmental pollutants
DDT, PCBs, dioxins and similar toxic and persistent organic pollutants tend to accumulate in living organisms and can reach harmful levels, particularly in species at the top of food chains. Certain heavy metals are harmful to plants, animals and man, particularly mercury, cadmium and lead. They can be stored in living tissue and remain there for a very long time.

The levels of mercury, lead and cadmium in Swedish forest soil have increased markedly during the past hundred years as a consequence of large-scale release of metals.
