The main sources of uncontrolled input of polychlorinated biphenylsin the environment of the Odesa industrial-and-urban agglomeration

Biological wastewater treatment plants as sources of environmental pollution by persistent organic pollutants (on the example of Odesa industrial-and-urban agglomeration)

“…In the work [2], we discovered the specifics of North Western Black Sea pollution by certain POPs based on expedite data from Ukrainian Scientific Center of Water Ecology. Though, the research data addressed a certain nomenclature of isomers of polychlorinated biphenyls, as well as hexachlorobenzene, which were accumulating in the sea environment throughout their continuous use in the former Soviet Union as part of POPcontaining pesticides [3] and as a result of transformer and condenser liquids being released into the environment [4]. Although, in our other work [5] it was discovered that such substances as polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofuran (PCDD/F) enter the water environment as parts of the wastewater being discharged there, the instrumental opportunities of monitoring, however, are not allowing to receive information regarding the contents of these toxic compounds.…”
