Evaluation of the degree of water bodies pollution and normalization of the permissible anthropogenic load on them
Abstract
The current approach to assessing the pollution of the aquatic environment does not take into account regional characteristics of waters and cannot reflect its real picture. To solve this problem, a methodology was developed for calculating a regional water pollution index using the regional background concentrations of elements and their toxicity according to the MPC criterion for fishery reservoirs. To normalize the permissible anthropogenic load on the aquatic environment, it is proposed to use an indicator of the amount of polluted water, taking into account both the volume of polluted water and the degree of pollution according to priority indicators. The approaches were tested for two water bodies, i.e. the Kenti lake-river system (Republic of Karelia) and the Imandra Lake (Murmansk region), which are subject to anthropogenic influence. It is shown that suggested methods can be used for any region and for various types of wastewater.
