摘要：
Research was carried out on the granulometric, mineral composition and fractional distribution of some elements in surface sediments of the Zeya River basin (Far East, Russia). The order of sediments’ pollution by heavy metals due to man-caused impact on the Zeya River’s ecosystem was determined. The compound forms of heavy metals in sediments were studied. It presented the most of the Fe, Ni, Cr, Mn, Co, Cu and Zn accumulated in bottom fraction; Pb and Cd—also in Fe and Mn hydroxides and bottom fractions. On average, 56% Pb, 83% Cd, 27–37% Cu, Co and Zn (of total amount) are held in geochemical moving forms.
