Lead uptake, toxicity, and detoxification in plants.
Lead has gained considerable attention as a persistent toxic pollutant of concern,partly because it has been prominent in the debate concerning the growing anthropogenic pressure on the environment. The purpose of this review is to describe how plants take lead up and to link such uptake to the ecotoxicity of lead in plants.Moreover, we address the mechanisms by which plants or plant systems de...

متن کاملTungsten Toxicity in Plants.
Tungsten (W) is a rare heavy metal, widely used in a range of industrial, military and household applications due to its unique physical properties. These activities inevitably have accounted for local W accumulation at high concentrations, raising concerns about its effects for living organisms. In plants, W has primarily been used as an inhibitor of the molybdoenzymes, since it antagonizes mo...
متن کاملChromium toxicity in plants.
Due to its wide industrial use, chromium is considered a serious environmental pollutant. Contamination of soil and water by chromium (Cr) is of recent concern. Toxicity of Cr to plants depends on its valence state: Cr(VI) is highly toxic and mobile whereas Cr(III) is less toxic. Since plants lack a specific transport system for Cr, it is taken up by carriers of essential ions such as sulfate o...
متن کاملSusceptibility to lead toxicity.
Adverse effects of lead on human health have been recognized for centuries. Nevertheless , current public health measures require a greater understanding of the pathobiology of chronic low level exposure (1-3). Such considerations are related to the question of what level of lead intake is harmful and why specific clinical manifestations of lead poisoning are encountered under particular circum...
