Methodological support of pollution monitoring of the Azov and Black Seas water bodies
The problems of pollution monitoring of the aquatic ecosystem components (water, bottom sediments, hydrobionts), associated with the complex composition of the identified toxicants and the presence of numerous interfering substances, are discussed. The article describes the issues and solutions in the process of determining the priority pollutants, which, according to the criteria of environmental hazard (toxicity, genotoxicity, сarcinogenicity, prevalence, frequency of occurrence), include petroleum products (hydrocarbons and resins), polycyclic aromatic hydrocarbons, organochlorine pesticides and polychlorinated biphenyls, heavy metals and arsenic, phenols and synthetic surfactants. To determine the toxicants, the optimal conditions for their isolation from water, sediments, organs and tissues of commercial fish and benthic organisms are elaborated, as well as for elimination of the factors that interfere with such determination. Evaluation of the amount of identified substances is carried out by highly informative analytical methods: high-performance liquid and gas chromatography, thinlayer chromatography, chromatography mass spectrometry, infrared and ultraviolet-visible spectrometry, luminescence spectroscopy, spectrometry in the visible region of the spectrum, atomic absorption and x-ray fluorescence spectroscopy. Methods of determination of all the controlled substances are standardized, certified and included in the State Register of methods for quantitative chemical analysis and assessment of the state of environment components, approved for the state environmental control and monitoring.
