Resistance to heavy metal toxicity in organisms under chronic exposure.
The rate of changes of heavy metal ions concentrations in the organism or biological system will determine the choice of strategy of realization of heavy metal ions effect and, consequently, the biological effect itself. Which of the possible strategies will dominate, depend on the rate of changes of concentration of heavy metal ions in biological systems, functional activity of organism at the...
متن کاملAcute Toxicity of a Heavy Metal Cadmium to an Anuran, the Indian Skipper Frog Rana cyanophlyctis
Background: There has been increasing awareness throughout the world regarding the remarkable decrease in amphibian population. For such amphibian population decline several causes have been given. Cadmium, a heavy metal is released both from natural sources (leaching of cadmium rich soils) and anthropogenic activities to the aquatic and terrestrial environments. This study evaluated the toxici...
متن کاملPlant Responses to Heavy Metal Toxicity
Plants, like all other organisms, have evolved different mechanisms to maintain physiological concentrations of essential metal ions and to minimize exposure to non-essential heavy metals. Some mechanisms are ubiquitous because they are also required for general metal homeostasis, and they minimize the damage caused by high concentrations of heavy metals in plants by detoxification, thereby con...
متن کاملHeavy Metal Toxicity
In general, irritable health concern related to heavy metal (accumulation) might be mainly divided into 2 types, i.e. heavy metal poisoning caused by excessive extrinsic exposure and genetic disorders such as Wilson disease (as reviewed by Osredkar et al. in this issue). As for the former type, unlike the latter one, it can be said that the health damage spread with the development of the civil...
متن کاملHeavy Metal Toxicity
Heavy metals are metallic elements which have a high atomic weight and a density much greater (at least 5 times) than water. There are more than 20 heavy metals, but four are of particular concern to human health: lead (Pb), cadmium (Cd), mercury (Hg), and inorganic arsenic (As). According to the U.S. Agency for Toxic Substances and Disease Registry. These four heavy metals are four of the top ...
