Limited liability partnership (LLP) KAZZINC - one of the largest industrial enterprises of East Kazakhstan region. From Kazzinc to the Irtysh water flow should be in the following order: river Filippovka, Quiet, Ulba and the Irtysh. Semey (former Semipalatinsk) is a large city on the Irtysh, the water of which is taken by "SemeyVodokanal" [1]. In the laboratory we investigated the possibility of using filamentous algae (of ulothrix, Spirogyra, cladophora) as biological monitoring in the waters of the Semipalatinsk region. Since the main products of "Kazzinc" LLP are metals such as zinc, cadmium, lead and copper, in the laboratory of elemental analysis of the branch of "Institute of Radiation safety and ecology" of National nuclear center of the Republic of Kazakhstan the absorption capacity of filamentous algae is determined in relation to zinc, copper, cadmium, iron and lead, as well as the residual concentration of heavy metals in the test water. In idle test identifies such elements as Be, Cr, Mn, Fe, Co, Ni, Cu, Zn, Sr, Cd, Cs, Pb, and U. The concentrations of these elements were determined by inductively coupled plasma mass spectrometry (ICP - MS) on the Agilent 7700x instrument and atomic emission spectrometry (NPP - ISP) on the iCAP 6300 Duo.
