Composition of Heavy Metals in the Water of the River Lopota and Floating Silt

Abstract

Like other small rivers in Georgia, the river Lopota, which is one of the most important left tributaries of the river Alazani, is ecologically less studied. Although, phosphorus - potassium fertilizers containing heavy metals from agricultural lands, leaching sediment , composts made of municipal and household waste are systematically leached into the river Lopota, the composition of heavy metals, copper, zinc, iron, lead, nickel, manganese is lower than it is accepted. This fact is promoted by water pH, under which these metals are hydrolyzed and their main mass is accumulated at the bottom, and the rest of it is absorbed in the floating silt. Therefore, they cannot have a negative impact on self-scouring and ecological condition of the river.
