In a number of heavy metals is very necessary for the sustenance of man and other living organisms, the so-called biogenic elements, there are also other causing the opposite effect, getting in a living organism, they lead to poisoning or death. These metals belong to the class of xenobiotics, that is, alien to life. Among the toxicant metals, a priority group was identified – Cd-cadmium, Cu-copper, As-arsenic, Ni-Nickel, Hg-mercury, Pb-lead, Zn-zinc, Cr-chromium and Fe-iron as the most dangerous to human and animal health. Of these, mercury, lead, and cadmium are the most toxic. The paper discusses pollution of surface waters of the rivers Irelyakh, Malaya Botuobiya and basin suspended solids-suspended solids, Fe-iron, Cu-copper, Zn-zinc Mn-manganese on the field “Irelyakhskoe placer” mining plant “Mirnyi” joint stock company “ALROSA”. The results of laboratory analyses of samples are presented, as well as the causes of contamination of river waters with these substances.
