Endocrine Disrupting

Continuous disposal of endocrine-disrupting chemicals (EDCs) into the environment can lead to serious human health problems and can affect aquatic organisms. A number of investigations suggested that final effluents of wastewater treatment plants are the main source of EDCs into the aquatic environment. A developed analytical method was used for the analysis of priority phenols as tert-butyl derivatives and phthalates in wastewater. Qualitative and quantitative analyses were performed by gas chromatography – mass spectrometry (GC–MS) using DB-5MS column. These compounds were evaluated using solid-phase extraction for raw and treated wastewater from a wastewater treatment plant. Concentrations of analytes ranged from below limit of detection to 570μgL-1 for phenols and below limit of quantification to 796μgL-1 for phthalates. Diethyl phthalate was the most prominent phthalate ester with pentachlorophenol for the corresponding phenol. The average percent removal varied from 52.63 to 100%. The result clearly shows that environmental endocrine disrupting chemicals are not completely removed from treated wastewater.

Abstract The project DemO3AC (demonstration of large-scale wastewater ozonation at the Aachen-Soers wastewater treatment plant, Germany) of the Eifel-Rur Waterboard contains the construction of a large-scale ozonation plant for advanced treatment of the entire 25 million m³/yr of wastewater passing through its largest wastewater treatment plant (WWTP). In dry periods, up to 70% of the receiving water consists of treated wastewater. Thus, it is expected that effects of ozonation on downstream water biocoenosis will become observable. Extensive monitoring of receiving water and the WWTP shows a severe pollution with micropollutants (already prior to WWTP inlet). (Eco-)Toxicological investigations showed increased toxicity at the inlet of the WWTP for all assays. However, endocrine-disrupting potential was also present at other sampling points at the WWTP and in the river and could not be eliminated sufficiently by the WWTP. Total cell counts at the WWTP are slightly below average. Investigations of antibiotic resistances show no increase after the WWTP outlet in the river. However, cells carrying antibiotic-resistant genes seem to be more stress resistant in general. Comparing investigations after implementation of ozonation should lead to an approximation of the correlation between micropollutants and water quality/biocoenosis and the effects that ozonation has on this matter.
