Land 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 rive...
