Abstract

This article presents the research results on effect of salinity to assimilation capacity of organic pollutants in the Cu De river’s water. It is one of the most important issues for studying the carrying capacity of biodegradable organic pollutants on the river basin. The results of three monitoring periods shown that the salinity (S-‰) is decreasing from estuary to upstream (from cross section MC₁ to cross section MC₅), fluctuating within 2,73 ÷ 22,27‰, meanwhile assimilation capacity of organic pollutants is increasing. The linear correlation between salinity and disintegrated organic pollutants (∆BOD_t) is presented by the equation:

Y(∆BOD_mh)= 10,72 – 1,166*S
