Contamination and ecological risk assessment of trace elements in sediments of the Anzali Wetland, Northern Iran

In this paper, concentrations of some heavy metals in surficial sediments of the International Anzali Wetland were measured, this wetland is located in the northern part of Iran. Sediment pollution levels were examined and analyzed using reliable pollution indices including Pollution Load Index (PLI...
