Geochemical Characterization of Organic Pollutants in Effluents Discharged from Various Industrial Sources to Riverine Systems

Abstract

The detailed characterization of the organic composition of industrial effluents discharged from various industrial branches and the distribution of the emitted pollutants in the surface waters in North Rhine-Westphalia have been done 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 and food effluents has been performed. Among a wide range of hydrocarbons detected in the petrochemical effluents, several novel organic wastewater constituents have been found for the first time. In the effluents from paper production plant, potential industrial indicators were distinguished, such as resin acids (abietic and dehydroabietic acids) and photoinitiators (Irgacure 184). The monitoring of the behaviour of certain environmentally relevant and newly described pollu-

Effect-Directed Analysis of Aryl Hydrocarbon Receptor Agonists in Sediments from the Three Gorges Reservoir, China

“…Tribenzylamine is a well-known extractant in industrial wastewater. − Thus, the compound was hypothesized to be associated with wastewater treatment. Dibenzylamine has been reported to be detected in environment samples, such as surface water and wastewater . It was reported as a byproduct during the rubber vulcanization process …”

Identification of specific organic contaminants in different units of a chemical production site

“…Seven of the compounds which were present in the effluent were also found in water samples from the receiving river system. 20 We present here an extended view inside the chemical production site "Industry A" by showing results from the sampling of different production units. In contrast to most studies which solely assess the chemical composition of treated industrial wastewaters, our approach included the investigation of untreated wastewaters from different production units as well as of corresponding treated wastewaters from the on-site wastewater treatment plant.…”
