摘要
FIELD: chemistry.;SUBSTANCE: method involves analysis of water samples collected on cross-sections located on areas of confirmed ecological well-being, determining the average sampling concentration of contaminants and the maximum allowable concentration of contaminants is determined based on minimum contamination using the formula: where Cm is the maximum allowable concentration of contaminants; Cb is the background concentration of chemical substances in water courses; is the average concentration of the substance; Sav is the mean-square deviation of concentration; tst is Student's coefficient at P=0.95; n is the number of samples collected on the area.;EFFECT: high accuracy of determination.;1 tbl
