how does cadmium affect the environment


People are exposed to cadmium through their diet, since cadmium is … The general content is very low. Human Health. Once absorbed, Cd is efficiently retained in the human body, in which it accumulates throughout life. ECOTOXICOLOGY AND ENVIRONMENTAL SAFETY 7, 151-159 (1983) The Effect of Cadmium on the Environment' JEROME F. COLE AND ROSALIND VOLPE International Lead Zinc Research Organization, Inc., 292 Madison Avenue, New York, New York 10017 Received August 1981 Information on the effect of cadmium in the environment reported during the past several years has raised … Cadmium levels in the soil, principally derived from natural sources, phosphate fertilisers and sewage sludge will naturally impact upon this cadmium uptake. Cadmium is an incredibly toxic metal and is ever-present in our environment primarily due to industrial dumping. Cadmium is found naturally in small quantities in air, water and soil. Cadmium is a non-essential element of the human body. In nature, cadmium is often symbiotic with zinc and lead. The widespread industrial use of cadmium has led to the exposure to human beings, animals, and the environment. Cadmium is also used in refining zinc metal and its byproduct is one of the leading causes of cadmium poisoning. Cadmium (Cd) is a soft, malleable, bluish white metal found in zinc ores, and to a much lesser extent, in the cadmium mineral greenockite. Sources of exposure to cadmium. decrease global environmental cadmium releases and reduce occupational and environmental exposure. Since cadmium is a metal, it does not break down and can build up over time. Cadmium Intake From Foods Cd is primarily toxic to the kidney, especially to the pro … How does cadmium get into the environment? Most of the cadmium produced today is obtained from zinc byproducts and recovered from spent nickel-cadmium batteries. Cadmium in controlled landfalls is virtually immobile, and is unlikely to have any effect on human health or the environment simply because it is so well contained (Eggenberger and Waber 1998, NUS 1987). Cadmium is a metal that also occurs naturally in the environment. Cadmium can be released into the air when household or industrial waste, coal or oil are burned. Forest fires and volcanoes also release some cadmium to the air. The Food and Drug Administration (FDA) limits the amount of cadmium in food colors to 15 parts per million (15 ppm). Cadmium and zinc are the same group of elements. How People Are Exposed to Cadmium. EPA does not allow cadmium in pesticides. It is often present in the form of a compound in nature. Cadmium (Cd), a by-product of zinc production, is one of the most toxic elements to which man can be exposed at work or in the environment. Since cadmium is a metal, it does not break down and can build up over time. Cadmium is found naturally in small quantities in air, water and soil. Under normal environmental conditions, it does not affect human health. Cadmium enters the environment through mining operations and the action of wind and rain. @article{osti_6338063, title = {Environmental impact of cadmium}, author = {Varma, M M and Katz, H M}, abstractNote = {The environmental impact of cadmium, a highly toxic metal with no known biological function, is evaluated. Cadmium can be released into the air when household or industrial waste, coal or oil are burned. It accumulates in the body through food and water, but also through the air we breathe and the environment in which we live. Human beings get exposed to cadmium through the foods they take and in the places they live or work. Cadmium can be released to the environment in a number of ways, including: natural activities, such as volcanic activity (both on land and in the deep sea), weathering and erosion, and river transport; However, this effect is secondary to the type of crop grown and the agricultural practices followed with respect to tillage, Aiming and crop rotation.
