The largest sources of cadmium in landfills are smelters, iron and steel plants, electroplating wastes, and battery production. Mine tailings generated as the result of zinc mining also have the potential to transfer cadmium to the ambient environment. Cadmium is mainly used as an anticorrosion coating in electroplating, as an alloying metal in
Forty-one bacterial strains were isolated from the rhizosphere soils and roots tissue of five dominant plants (Artemisia argyi Levl., Gladiolus gandavensis Vaniot Houtt, Boehmeria nivea L., Veronica didyma Tenore, and Miscanthus floridulus Lab.) colonizing a cadmium (Cd)-contaminated mining area (Huayuan, Hunan, China).
Response of plants to cadmium stress Abstract. In this article we discuss cadmium pollution in the environment and the various ways plants take up cadmium and respond to its accumulation. The increased development of metallurgical and mining industries is primarily responsible for the increases in cadmium pollution in the environment. Another

Cadmium metal (Cd) is a silver-white solid, tinged with blue. Cadmium is found in cadmium fumes (CdO) and cadmium compounds. Workers may be harmed from exposure to cadmium. It is a highly toxic carcinogenic that is harmful to most of the body''s systems, especially to the lungs, bones, and kidneys. The level of exposure depends upon the dose, duration, and work being done.
· Cadmium is produced by mining, refining, or smelting of zinc, and is a lesser byproduct of the production of copper and lead (Bi et al., 2006). Therefore, cadmium is produced in relation to zinc, instead of through its direct production. Cadmium production almost doubled from 1950 to 1990, about 20,000 tons annually, while its consumption in ...

Cadmium (Cd) is an unessential trace element in plants that is ubiquitous in the environment. Anthropogenic activities such as disposal of urban refuse, smelting, mining, metal manufacturing, and application of synthetic phosphate fertilizers enhance the concentration of Cd in the environment and are carcinogenic to human health.

Cadmium (Cd) is a soft, malleable, bluish white metal found in zinc ores, and to a much lesser extent, in the cadmium mineral greenockite. Most of the cadmium produced today is obtained from zinc byproducts and recovered from spent nickel-cadmium batteries. First discovered in Germany in 1817, cadmium found early use as a pigment because of its ...
Mine spoils and other soils contaminated with cadmium, copper, lead and zinc show natural colonization by species which have strategies of avoidance or tolerance of metal toxicities. The distribution of plants on such substrata in the British Isles is examined in the light of present knowledge of such strategies. Evolutionary processes mediating the selection of tolerant individuals and ...
mining, use of extensive pesticides, insecticides, fungicides, and other agrochemicals uses were significant causes of environment pollution and causes of most concern. Heavy metals, such as cadmium, copper, lead, chromium, manganese, iron

Cadmium can be released to the environment through natural activities (volcanoes, wildfires, weathering and erosion of rocks), human activities (tobacco smoking, mining, smelting and refining, fossil fuel combustion, incinerating or recycling used
· Connecting a remote mine to a central treatment plant via pipeline is expensive, time-consuming, and requires negotiation of complex right-of-way issues, so mining operations typically require decentralized treatment of water and wastewater. Decentralization, in a nutshell, means siting treatment near the water source, demand, or ideally both.
