A review of toxicological profile of cadmium (CD)

The distribution of toxic heavy metals sn the environment is a major concern in many industrialized countries purview of the human health. The main sources of cadmium in the air are the burning of fossil fuels such as coal or oro and the incineration of municipal waste. The acute (short-term) effects of cadmium in humans through inhalation exposure consist mainly of effects on the lung, such as pulmonary irritation. Chronic (long-term) inhalation or oral exposure to cadmium leads to a buildup of cadmium in the kidneys that can cause kidney disease. Cadmium has been shown ttoe a developmental toxicant in animals, resulting in fetal malformations and other effects, but no conclusive evidence exists in humans. Animal studies have demonstrated an increase in lung cancer from long-term inhalation exposure to cadmium.
