EFFECT OF ATMOSPHERIC NITROGEN DEPOSITION TO WATER QUALITY OF DAM RESERVOIRS AND INFLOW RIVERS

Abstract

Using water quality data of dam reservoirs and their inflow rivers in the whole country, we compared the T-N and T-P concentration of them. The results show that the T-N level of some dam reservoirs, which seem to have few contaminations by human and livestock, is high and nitrate concentration in their inflow rivers is also high. This result suggests that some dam reservoirs undergo influence of atmospheric nitrogen deposition.
