• CADMIUM AND CADMIUM COMPOUNDS

    plants and soil can lead to cadmium entering the foodchain through foliar absorption or root uptake. The rate of cadmium transfer depends on a variety of factors, including deposition rates, type of soil and plant, the pH of the soil, humus content, availability of organic matter, treatment of the soil with fertilizers, meteorology, and the presence of other elements, such as zinc (WHO, 2000 ...

    Cadmium mainly accumulates in the kidneys and liver and can lead to serious kidney failure, nephrotoxicity, renal stone formation, bone disease and persistent proteinuria at high exposures. Cadmium stays in the body a very long time and can build up from many years of exposure to low levels. Recent studies have shown that the effects are reversible at low exposures, once exposure to cadmium .
