This is confirmed that bacteria and other living organisms are not able to decompose or excrete the heavy metals, so heavy metals concentrate and accumulate in their tissues and cause toxicity in other organisms in high levels of food chain via biomagnifications and transfer by organisms to the intermediate levels of food chain for instance macrobenthos. Mean concentration of lead was estimated...

Interpolated contour maps drawn for aluminum, copper and molybdenum in downstream monitoring boreholes of water dam in Miduk Copper Complex and the values of pH, redox potential (Eh) and distance from water dam indicate different trends of variation and behavior of these three elements in downward groundwater resources. As these maps exhibit, aluminum is dominant in the most alkaline (pH = 9-11...
