Toxic Elements

Metals that have no biological use and which humans did not evolve to metabolise, such as lead, mercury and cadmium etc., tend to be present at low levels in the environment and food chain, but over a lifetime, or following an acute exposure, can accumulate in body tissues. They can then interfere with normal biological function as the level of exposure or accumulation increases.

We are also exposed to man-made sources of toxic elements (e.g. aluminium in antiperspirants, arsenic in wood preservatives etc.), and the living world can also accumulate environmental toxic metals which subsequently enter the human food chain (e.g. some varieties of rice have relatively high arsenic levels and seafood can be contaminated with mercury and other metals).
