Trace metal pollution in the Mediterranean Sea
In the Mediterranean Sea, the distribution of dissolved zinc, copper, lead and cadmium is primarily controlled by marine circulation, surface source dynamics and biological new production. We show that the present relatively high content of these metals in the surface layer is due to non-steady-state cycles as a result of source increases probably following increases in industrial, agricultural...

متن کاملLand use effects on heavy metal pollution of river sediments in Guilan, southwest of the Caspian sea
Studies have showed the River Siahroud is the main contributor to the present pollution of Anzali Wetland in Guilan. Therefore, this study was initiated to evaluate the spatial distribution of metals pollution on the River Siahroud sediments in Guilan.Surfacial river sediment samples along this river were taken during five consecutive seasons at eight sampling stations and analyzed for availabi...
متن کاملEvaluation of the status of heavy metal pollution in surface water and sediments of the Nil River (North Eastern Algeria)
Water and sediment samples were collected from six different stations, located along the Nil River between February and June 2015. Concentrations of cadmium, lead, zinc, and copper were determined. The extent of the sediment pollution was assessed, using the multiple pollution indices, namely contamination factor (CF), pollution load index (PLI), and the geoaccumulation index (Igeo). The result...
