    Concentrations of 56 potential endocrine disrupting chemicals in 56 European wastewater treatment plant effluents by LC-HRMS adn LC-MS/MS analysis (2022)
    PANGAEA
    Details
    Publication Date: 2024-04-20
    Description: 79 potential endocrine disrupting chemicals (EDCs) were investigated in 56 effluent samples from 52 European wastewater treatment plants (WWTPs). The samples were collected between August 2017 and April 2019, using on-site large volume solid phase extraction (LVSPE) (Schulze et al., 2017). Chemical target analysis by liquid chromatography high-resolution and tandem mass spectrometry (LC-HRMS and LC-MS/MS, respectively) resulted in 56 detected compounds. Different capacities and conventional treatment technologies, as well as two advanced treatment technologies are included. One sample was taken at a WWTP with activated carbon treatment. Three WWTPs applying ozonation were sampled before and after this treatment step, providing two samples each. One of these WWTPs had already been sampled before the upgrade, resulting in a total of 56 (52+4) samples. More information can be found in Finckh et al. (2022). The two main objectives of this study were (i) to compare three different receptor-based estrogenicity assays (ERα-GeneBLAzer, p-YES, ERα-CALUX®), and (ii) to investigate a combined approach of chemical target analysis and receptor-based testing for estrogenicity, glucocorticogenic activity, androgenicity and progestagenic activity (ERα-, GR-, AR- and PR-GeneBLAzer assays, respectively) in treated wastewater.

    Concentrations of 366 emerging chemicals in 56 European wastewater treatment plant effluents by LC-HRMS target screening (2022)
    PANGAEA
    Details
    Publication Date: 2024-04-20
    Description: 499 emerging chemicals (ECs) were investigated in 56 effluent samples from 52 European wastewater treatment plants (WWTPs). The samples were collected between August 2017 and April 2019, using on-site large volume solid phase extraction (LVSPE) (Schulze et al., 2017). Chemical target screening by liquid chromatography high-resolution mass spectrometry (LC-HRMS) resulted in 366 detected compounds. Different capacities and conventional treatment technologies, as well as two advanced treatment technologies are included. One sample was taken at a WWTP with activated carbon (AC) treatment. Three WWTPs applying ozonation were sampled before and after this treatment step, providing two samples each. One of these WWTPs had already been sampled before the upgrade, resulting in a total of 56 (52+4) samples. More information can be found in Finckh et al. (2022). The two main objectives were (1) to extend our knowledge on chemicals occurring in treated wastewater, and (2) to identify and prioritize compounds of concern based on three different risk assessment approaches for the identification of consensus mixture risk drivers of concern.

    The lowland stream monitoring dataset (KgM, Kleingewässer-Monitoring) 2018, 2019 (2021)
    PANGAEA
    Details
    Publication Date: 2024-04-20
    Description: Plant protection products in the environment are partly responsible for the progressive loss of biodiversity. The mostly insufficient ecological status of surface waters is often explained by habitat degradation and excessive nutrient input. But what role do plant protection products play in this context? The Kleingewässermonitoring (KgM) project provides a worldwide unique quantitative assessment of the impact of pesticides from diffuse agricultural sources on small and medium-sized streams. The dataset comprises 124 monitoring stream sections all over Germany covering a wide pollution gradient where consistent measurements were carried out in 2018 and 2019 during the major pesticide application period from April to July. These measurements include event-driven sampling to record surface rainfall-induced short-term peak concentrations in addition to regular grab sampling of pesticides and a wide range of other pollutants resulting in more than 1,000 water samples. All further relevant anthropogenic and environmental parameters reigning ecological stream quality were recorded comprehensively (morphological and stream bed structure, temperature, flow velocity, dissolved oxygen, pH, catchment land use, stream profile). The dataset also contains effect monitoring data featuring sampled invertebrate communities and bioassay analyses of water samples. The data enables an assessment of pesticide exposure and related effects as well as the analysis of complex causal relationships in streams.

    Concentrations of 504 organic micropollutants in 445 European streams by LC-HRMS target screening (2023)
    PANGAEA
    In:  Helmholtz Centre for Environmental Research - UFZ
    Details
    Publication Date: 2024-04-20
    Description: The data file contains measured environmental concentrations of organic micropollutants in European streams and additional hydrological parameters (stream order, urban discharge fraction) of the investigated sites. A total of 445 surface water samples were collected during various sampling campaigns between 2016 and 2019. Chemical target screening of 610 compounds by liquid chromatography high-resolution mass spectrometry (LC-HRMS) resulted in 504 detected compounds. The measured environmental concentrations of the detected compounds ranged from 1 ng/L to 74 µg/L (3-cyclohexyl-1,1-dimethylurea). Detection frequencies ranged from one site (0.2 %) to 339 sites (76 %). More information can be found in Finckh and Carmona et al. (2024) DOI: 10.1016/j.envint.2023.108371. The main objective of this study was to quantify and characterise chemical footprints in European streams.
