Organisch-chemische Charakterisierung von Abwässern verschiedener industrieller Direkteinleiter und ihr Umweltverhalten in fluviatilen Systemen Nordrhein-Westfalens
Zusammenfassung der Projektergebnisse
The detailed description of the organic composition of industrial effluents discharged from various industrial branches and the distribution of the emitted pollutants in riverine systems have been performed with the use of non-target screening analyses. Based on the characterization of molecular structures of wastewater constituents, their quantification as well as the available information on their origin and industrial applications, the identification of typical organic representatives for petrochemical, chemical, paper and food production effluents has been has been achieved. The approach proposed in this investigation goes beyond the scope of the standard environmental regulation procedures which include only the monitoring of basic pollution parameters of industrial wastewaters. The determination of the distribution of organic constituents in within an industrial plant is important for the evaluation of a potential anthropogenic impact of the industrial discharges resulted from occasional releases of the pollutants during industrial accidents that can lead to unpredictable environmental effects due to the lack of ecotoxicological data for many of them. Furthermore, screening analyses allowed identification new contaminants, which accounts for better explanation of various ecotoxicological effects observed for wastewater discharged from certain industrial branches. The monitoring of the behavior of certain environmentally relevant and newly described pollutants in the contaminated river systems allowed the identification of several industrial site-specific markers. In this case the river water analyses provided the most valuable results. Surprisingly, despite the hydrophobic properties of the investigated compounds, their accumulation in the analysed sediment was in significant. Thus, this study demonstrates the relevance of source specific organic indicators to be an important tool for comprehensive assessment of the potential impact of industrial activities to the contamination of the aquatic environment. Based on the extensive identification of source specific substances, the system of marker compounds might allow rapid determination of the industrial impact on rivers not only per se but also as a result of industrial accidents or malfunctions of wastewater treatment facilities. The detailed evaluation of the indicative compounds in the industrial effluent should be accompanied with toxicological and ecotoxicological investigations of novel environmental contaminants. This approach applied on the regular basis will prove useful for the environmental monitoring measures and efficient identification of contamination sources. In conclusion it is necessary to notice, that for the effective evaluation of industrial indicators and site-specific markers, there is a necessity to pursue the application of the non-target screening procedure towards industrial effluents as well as the environmental monitoring more systematically taking into account the technical and hydrological changes occurring in industrial and natural systems.
