Abstract

The pollution of the Amur water with organic compounds at the Khabarovsk water-supply point has been analyzed by means of gas chromatography-mass spectrometry (GC-MS). Among environmental pollutants, petroleum hydrocarbons and alkylphtalates predominate. A number of potentially dangerous compounds present in the waste water of the rubber industry works and some other dangerous compounds including a herbicide of TsP 32179 type were detected. Pollution with these compounds has a stable character. The concentrations of a number of critical substances did not exceed the MPCs; however, many compounds are toxic micro-impurities. A great part of the identified compounds are of microbiological origin.
