INFLUENCE OF FACILITIES OF INTENSIFICATION ON CONTAMINATION OF PONDS BY HEAVY METALS

The ratio of outwashing of heavy metals (Fe, Zn, Mn, Cu, Ni, Co, Pb, Cd) from the intensifiers (all-mash, organic fertilizers, ammophos, saltpetre, superphosphate and lime) was measured by laboratory experiment. Moreover was evaluated the risk of ponds contamination by the heavy metals of water under the conditions of intensive fish growing.
