Уровень загрязнения водных объектов эфирами фталевых кислот и продукты их трансформации под воздействием природных и техногенных факторов

Abstract

The present study gives insight into the problem of water contamination with phthalic acid esters (PAEs) and their transformation in natural and technological systems. The contamination levels of PAEs were determined in the water samples taken from the Moscow River in high environmental stress areas. The levels were associated with the residential area use, and the comparison of the Moscow River contamination levels with the surface water contamination worldwide was made. The transformation of common PAE in water - dibutyl phthalate (DBP) -was studied under UV-radiation to characterize the influence of this factor on water quality in natural and technological systems. The products of PAEs transformation under UV-radiation were identified using gas chromatography mass-spectrometry (GC-MS).
