The current study was conducted on the valley of Duhok and agricultural lands irrigated from it, where three sites were identified for collecting samples quarterly soil sediment using clean plastic bags purpose measuring lead, nickel, cobalt copper. Pollution load index (PLI), Nemerow pollution (PIN), Potential Ecological Risk (PER) Geo-accumulation Index (Igeo) also calculated according to int...

Drinking water quality is a critical factor affecting human health particularly in natural resource-dependent countries including Nigeria. Hydrocarbon related pollution, mining waste, microbial load, industrial discharge and other anthropogenic stressors degrade drinking coastal communities pose serious public ecological risks. This study evaluated the physicochemical properties of selected (Ok...

Over the last few decades, Anzali wetland has been at risk of pollutants, especially from heavy metals. The present research analyzes some physical and chemical properties and heavy metals concentration in 27 points in nine stations of Anzali wetland. The samples of each station have been mixed, acidic digested, and analyzed by inductively coupled plasma mass spectrometry (ICP-MS). The mean con...
