Heavy metals that enter marine environment and remain in the water as well as the sediments are accumulated by aquatic organisms, thus becoming highly good indicators to monitor metal accumulation in the long run. Metals are potentially harmful to humans and most organisms at varied levels of exposure and absorption. Northern East Mediterranean Sea is a crucial region as it is an area, shared b...

Environmental problems related to heavy metals have a long history. Heavy metals have toxic properties, leading to adverse effects on human and ecosystem health even in small doses. Another problem-causing property is their non-degradability: once they enter the environment they will remain there for a long time. Metals tend to accumulate in soils and sediments, with immobilisation due only to ...

Accumulation of heavy metals from various oxides with adsorbed cadmium by wetland plant Phragmites australis was studied to evaluate the fate of heavy metals in the sediment of constructed wetlands. Hoagland solution was used as nutrition supply, and single metal oxide with adsorbed cadmium was applied as contaminant to study the accumulation characteristics of cadmium and the substrate metals ...

A survey was conducted to monitor the influence of city sewage irrigation on the heavy metal build up in soils around Bhopal. Concentration of the heavy metals in effluent was within safe limits. Diethylene triamine penta acetic acid extractable Pb, Cd, Ni, Co, Cr, Fe, Mn, Zn and Cu in the sewage irrigated surface soil ranged 3.5-6.8, 0.15-0.40, 2.56-5.58, 1.59-3.89, 0.45-0.55, 3.5-15.8, 3.6-8....

background: heavy metals tend to bioaccumulate in living organisms, and their accumulation has been a major concern. as mammals are known to excrete heavy metals via their bile, it seems to be very promising to analyse metal burdens of par-asites that infect the biliary tree such as liver flukes of the genus fasciola . the pre-sent study was carried out to evaluate f. hepatica and f. gigantica ...

Four heavy metals were measured in forty-nine topsoil samples collected fromagricultural areas in Siakh-Darengoun, Iran. The goals were to investigate soil spatialdistribution patterns of metals; their potential ecological risk; and sources. The Hakansonpotential ecological risk index and index of geo-accumulation (Igeo) were used forevaluating t...
