METHOD OF DETERMINING STANDARD MAXIMUM ALLOWABLE CONCENTRATION OF CONTAMINANTS IN WATER BODIES

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 Cis the maximum allowable concentration of contaminants; Cis the background concentration of chemical substances in water courses;is the average concentration of the substance; Sis the mean-square deviation of concentration; tis Student's coefficient at P=0.95; n is the number of samples collected on the area.EFFECT: high accuracy of determination.1 tbl
