levels of contaminants in fish are of particular interest because of the potential risk to humans consuming them. this paper examines the levels of cadmium, lead, zinc and copper in liver and muscle tissue of esox lucius and in sediments from the anzali international wetland in iran. the wetland is a nursery and feeding habitat for fish species both from the lagoon and the caspian sea, which ar...

The status of metal concentrations including Pb, Cd, Cu, Ni, Zn and Fe in six species of Padina were determined in polluted (Nayband Bay) and unpolluted (Bostaneh port) areas on the Coast of the Persian Gulf. The mean concentrations of metals in the sediment of two locations were: Pb (12.64), Cd (3.59), Cu (21.74), Ni (17.00), Zn (32.00) and Fe (677.53) µg g-1 dry weight, respectively. In ...

Levels of the heavy metals Copper (Cu), Zinc (Zn), Lead (Pb), Cadmium (Cd), Chromium (Cr), Nickel (Ni), Iron (Fe) and Manganese (Mn) were determined by graphite furnace atomic absorption spectrophotometer (Model 67OG) in coastal water, sediments and soft tissues of the Saccostrea cucullata, from the intertidal zone at five stations in the Gulf of Chabahar on the Iranian coasts along the Oman Se...

background: the presence of heavy metals in aquatic and terrestrial ecosystems causes harmful effects to living organisms in the environment. this research aimed to determine the potential of activated pumice stone (aps) as a sorbent for the removal of cd, cu, and zn from wastewater. methods: this research was conducted during 2013 on a laboratory scale. the study was performed using batch expe...

This study was carried out to find any relative concentrations of the trace metals (Cu, Cd, Zn and Pb) in the liver and the kidney of Acipenser persicus and in the surficial sediments of the west coast of The Southern Caspian Sea. Twenty five samples of the Acipenser persicus (Persian sturgeon) and ten samples of the sediments were taken from five fishing stations in autumn 2001. The tissues we...
