Abstract Increasing production and use of chemicals awareness their impact on ecosystems humans has led to large interest for broadening the knowledge chemical status environment human health by suspect non-target screening (NTS). To facilitate effective implementation NTS in scientific, commercial governmental laboratories, as well acceptance managers, regulators risk assessors, more harmonisation is required. address this, NORMAN Association members involved activities have prepared this...
The widespread utilization of organic compounds in modern society and their dispersion through wastewater have resulted extensive contamination source drinking waters. vast majority these are not regulated outfalls or water while trace amounts certain can impact aquatic wildlife. Hence it is prudent to monitor contaminants sources until sufficient toxicological data relevant humans becomes available. A method was developed for the analysis 36 (TOrCs) including pharmaceuticals, pesticides,...
Worldwide, ozonation of secondary wastewater effluents is increasingly considered in order to decrease the load organic contaminants before environmental discharge. However, despite constantly growing knowledge over past few years, characterization transformation products (TPs) still a major concern, particularly because such TPs might remain biologically active. It has been shown for selected tertiary amine pharmaceuticals that they react with ozone and form corresponding N-oxides. This...
Interpreting the fate of wastewater contaminants in streams is difficult because their inputs vary time and several processes synchronously affect reactive transport. We present a method to disentangle various influences by performing conservative-tracer test while sampling stream section at locations for chemical analysis micropollutants. By comparing outflow concentrations with tracer signal convoluted inflow series, we estimated reaction rate coefficients calculated contaminant removal...
The application of nontargeted strategies based on high-resolution mass spectrometry (HRMS) directed toward the discovery metabolites known contaminants in fish is an interesting alternative to true nontarget screening. To reduce prolonged and costly laboratory experiments, recent advances computing power have permitted development comprehensive knowledge-based software predict metabolic fate chemicals. In addition, machine-based learning tools allow prediction chromatographic retention...
Cylindrospermopsin (CYN) is a potent toxic alkaloid produced by number of cyanobacteria frequently found in lakes and reservoirs used as drinking water sources. We report for the first time detailed pathways degradation CYN treatment with ozone. This was accomplished use ultra-high-performance liquid chromatography (UHPLC)-quadrupole time-of-flight mass spectrometry (QTOF MS), which revealed that readily degraded ozone at least 36 transformation products. Structural similarities among major...
Abstract Non-target analysis (NTA) employing high-resolution mass spectrometry is a commonly applied approach for the detection of novel chemicals emerging concern in complex environmental samples. NTA typically results large and information-rich datasets that require computer aided (ideally automated) strategies their processing interpretation. Such do however raise challenge reproducibility between within different workflows. An effective strategy to mitigate such problems implementation...
Ethoxyquin (EQ) is an additive present in fish feed and its fate should be carefully characterized due to food safety concerns regarding this compound. Therefore, the objective of work was identify transformation products (TPs) EQ Atlantic salmon. Salmon independent tanks were given containing ethoxyquin concentrations 0.5 mg/kg, 119 mg/kg or 1173 for 90 days. After feeding trial, salmon fillets extracted acetonitrile analyzed by liquid chromatography with traveling-wave ion mobility...
Trace organic compounds (TOrCs) continue to be detected in drinking water, and their recalcitrance makes them difficult attenuate without installing expensive advanced treatment processes. Because human consumption is a small portion of net household water use, point‐of‐use (POU) devices may provide additional security against contaminants. This research evaluated three pitcher two refrigerator POU using waters. Refrigerator removed more TOrCs over the manufacturer's expected lifetime terms...
Ethoxyquin (EQ; 6-ethoxy-2,2,4-trimethyl-1,2-dihydroquinoline) has been used as an antioxidant in feed for pets and food-producing animals, including farmed fish such Atlantic salmon. In Europe, the authorization use of EQ a additive was suspended, due to knowledge gaps concerning presence toxicity transformation products (TPs). Recent analytical studies focusing on detection TPs salmon fillets reported total 27 TPs, comprising both known previously not described TPs. We devised applied...
