The effluents of eight municipal wastewater treatment plants (WWTP) in Western Europe were analyzed by liquid-chromatography−mass spectrometry for the occurrence 36 polar pollutants, comprising household and industrial chemicals, pharmaceuticals, personal care products. In a long-term study three WWTP over 10 months, sulfophenyl carboxylates ethylene diamino tetraacetate (EDTA) detected above μg/L on average, while benzotriazoles, benzothiazole-2-sulfonate, diclofenac, carbamazepine showed...
The discharge of persistent and mobile organic chemicals (PMOCs) into the aquatic environment is a threat to quality our water resources. PMOCs are highly polar (mobile in water) can pass through wastewater treatment plants, subsurface environments potentially also drinking processes. While few such compounds known, we infer that their number actually much larger. This Feature highlights issue from an environmental perspective assesses gaps appear exist terms analysis, monitoring,...
The antiozonant N-phenyl-N'-(1,3-dimethylbutyl)-p-phenylenediamine (6-PPD) is added to tires increase their lifetime and emitted with tire road wear particles into the environment. Recently, one of its transformation products (TPs), 6-PPD quinone (6-PPDQ), has gained attention due toxicity towards coho salmon. In this study, abiotic oxidative investigated by a series ozonation experiments in lab followed analysis TPs using liquid chromatography-high resolution-mass spectrometry (LC-HRMS). A...
Few studies have examined the exposure of small streams (< 30 km2 catchment size) to agriculturally used pesticides, compared large rivers. A total 105 sites in 103 agricultural were investigated for 76 pesticides (insecticides, herbicides, fungicides) and 32 pesticide metabolites spring summer over two years (2018 2019) during dry weather rainfall using event-driven sampling. The median concentration was 0.18 µg/L, with 9 per sample on average (n = 815). This is significantly higher than...
Tire and road wear particles (TRWPs) are one of the main sources particulate traffic emissions, but measured data on TRWP contents in environment scarce. This study aims at identifying organic compounds suitable as quantitative markers for TRWPs by a tiered multistep selection process involving nontarget screening subsequent identification liquid-chromatography high-resolution mass spectrometry. Starting from several thousands signals recorded extract tire particles, rigorous considered...
Abstract Background The NORMAN Association ( https://www.norman-network.com/ ) initiated the Suspect List Exchange (NORMAN-SLE; https://www.norman-network.com/nds/SLE/ in 2015, following collaborative trial on non-target screening of environmental water samples by mass spectrometry. Since then, this exchange information chemicals that are expected to occur environment, along with accompanying expert knowledge and references, has become a valuable base for “suspect screening” lists....
Permanently charged and ionizable organic compounds (IOC) are a large diverse group of belonging to many contaminant classes, including pharmaceuticals, pesticides, industrial chemicals, natural toxins. Sorption mobility IOCs distinctively different from those neutral compounds. Due electrostatic interactions with sorbents, existing concepts for describing sorption, by extension mobility, inadequate IOC. Predictive models developed based on octanol–water partitioning (Kow) organic-carbon...
N-(1,3-Dimethylbutyl)-N′-phenyl-p-phenylenediamine (6-PPD) is a widely used antioxidant in tire rubber known to enter the aquatic environment via road runoff. The associated transformation product (TP) 6-PPD quinone (6-PPDQ) causes extreme acute toxicity some fish species (e.g., coho salmon). To interpret species-specific toxicity, information about biotransformation products of 6-PPDQ would be relevant. This study investigated toxicokinetics and zebrafish embryo (ZFE) model. Over 96 h...
When chemical pollutants enter the environment, they can undergo diverse transformation processes, forming a wide range of products (TPs), some them benign and others more harmful than their precursors. To date, majority TPs remain largely unrecognized unregulated, particularly as are generally not part routine risk or hazard assessment. Since many formed from oxidative processes polar precursors, may be especially relevant in context persistent, mobile, toxic (PMT) very persistent mobile...
A set of three benzotriazole corrosion inhibitors was analyzed by liquid chromatography−mass spectrometry in wastewaters and a partially closed water cycle the Berlin region. Benzotriazole (BTri) two isomers tolyltriazole (TTri) were determined untreated municipal wastewater with mean dissolved concentrations 12 μg/L (BTri), 2.1 (4-TTri), 1.3 (5-TTri). Removal conventional activated sludge (CAS) treatment ranged from 37% for BTri to insignificant removal 4-TTri. In laboratory batch tests...
