To achieve these goals, we need to determine the environmental factors and underlying physiological mechanisms that regulate the uptake and effects of toxic metals (Cu, Cd, and Zn) and interactive nutrient metals (Mn, Zn and Fe) in representative phytoplankton species. We will then combine this information with data on environmental variations in controlling factors (e.g. free ion concentration...

Heavy metals i.e. Copper (Cu), Zinc (Zn), Manganese (Mn), Iron (Fe), Cadmium (Cd), Nickel (Ni), Mercury (Hg) and Arsenic (As) were analyzed in 35 samples of the fish muscle, from East Kolkata Wetlands (EKW). The concentration of heavy metals was in order of, Fe > Zn > Cu > Mn > Ni > As > Hg > Cd. The essential metals, such as iron, zinc, copper and manganese were in higher concentrations and, t...

A series of meetings concerning metal toxicology have been organized by the Scientific Committee on the Toxicology of Metals under the Permanent Commission and International Association on Occupational Health. Accumulation of toxic metals with special reference to their absorption, excretion, and biological half-times was discussed in Slanchev Bryag, Bulgaria, 1971, and in Buenos Aires, 1972. D...

Heavy metals such as cadmium (Cd), mercury (Hg), lead (Pb), chromium (Cr) and platinum (Pt) are a major environmental and occupational hazard. Unfortunately, these non-essential elements are toxic at very low doses and non-biodegradable with a very long biological half-life. Thus, exposure to heavy metals is potentially harmful. Because of its ability to reabsorb and accumulate divalent metals,...

Heavy metals are ubiquitous contaminants of the marine environment and can accumulate and persist in sediments. The toxicity of metal contaminants in sediments to organisms is dependent on the bioavailability of the metals in both the water and sediment phases and the sensitivity of the organism to the metal exposure. This study investigated the effects of two metal contaminants of concern (CdC...
