Summary:
A number of studies are currently conducting with purpose of seasonal and annual monitoring of the Caspian Sea. A lot of statistical data are collected during these monitorings. But the issue of the harmful concentrations of metal to the inhabitants of the Caspian Sea is still open.
The paper presents the results of a study of lethal dose (LC50) of some metals on Caspian Sea phytoplankton. Algae Chaetoceros Tennissimus were used as a test material, and Mo, Al, Co, As, Ni, Mn, Cr, Zn, Sb, Sn, Pb, Cu, Se as the analyzed metals. Accoriding to the obtained data a list of increased toxicological effects of these metals on algae Chaetoceros tennissimus was prepared. The results of study showed that the most toxic metals are copper and selenium, the less toxic metals are molybdenum and aliminium.

Keywords: Caspian Sea, heavy metals, lethal concentration, lethal dose (LD50), phytoplankton, toxicity
