Aqueous film-forming foams (AFFFs) are widely used to extinguish liquid fires due their properties. AFFF formulation historically contains per- and polyfluoroalkyl substances (PFASs) that can be very persistent pose a health risk biota humans. Detailed analysis of the chemical composition AFFFs provide better understanding on potential environmental impact ingredients. In this study, novel workflow combining target analysis, nontarget screening (NTA), total fluorine (TF) inorganic fluoride...
Microplastics are ubiquitous in aquatic ecosystems, but little information is currently available on the dangers and risks to living organisms. In order assess ecotoxicity of environmental microplastics (MPs), samples were collected from beaches two islands Guadeloupe archipelago, Petit-Bourg (PB) located main island Marie-Galante (MG) second archipelago. These have a similar polymer composition with mainly polyethylene (PE) polypropylene (PP). However, these very dissimilar regard their...
Microplastics (MPs), widely present in aquatic ecosystems, can be ingested by numerous organisms, but their toxicity remains poorly understood. Toxicity of environmental MPs from 2 beaches located on the Guadeloupe archipelago, Marie Galante (MG) and Petit-Bourg (PB) near North Atlantic gyre, was evaluated. A first experiment consisted exposing early life stages zebrafish (Danio rerio) to at 1 or 10 mg/L. The exposure particles water induced no toxic effects except a decrease larval swimming...
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...
Monitoring the vast number of micropollutants in environment by using comprehensive chemical screening is a major analytical challenge. The aim this study was to evaluate analysis method for purposes fish muscle samples comparing sample preparation methods broad range mid-to non-polar contaminants. Five extraction and three clean-up were evaluated 60 compounds with log Kow between 0.8 8.3 fish. Both fresh freeze-dried tissue sodium sulphate blanks included assess recoveries matrix effects....
During a fire event, potentially hazardous chemicals are formed from the combustion of burning materials and released to surrounding environment, both via gas soot particles. The aim this investigation was study if firefighting techniques influence emission in phase Five full-scale tests were extinguished using four different techniques. A nontarget chemical analysis approach showed that important contaminants separating brominated flame retardants (BFRs), organophosphate (OPFR), polycyclic...
To facilitate the study of potential harmful compounds sorbed to microplastics, an effect-directed analysis using DR CALUX® assay as screening tool for Aryl hydrocarbon receptor (AhR)-active in extracts marine deployed microplastics and chemical hydrophobic organic (HOCs) was conducted. Pellets three plastic polymers (low-density polyethylene (LDPE), high-density (HDPE) high-impact polystyrene (HIPS)) were at Heron Island Great Barrier Reef, Australia, up 8 months. Detected AhR-mediated...
With the recent improvements in high-resolution mass spectrometry (HRMS), retrospective chemical analysis has been increasingly used environmental sciences. This enables new insights into content of previously analysed samples with data methods or information about emerging contaminants. study aimed to conduct an in-depth investigation various indoor dust using analysis. The were extracted liquid-solid extraction without clean-up increase coverage and thereafter both liquid chromatography...
This study aims at estimating which pesticide active substances (ASs) are the best candidates to potential further degradation of AS above 120°C. To achieve this, a prioritisation list was built following five consecutive criteria. first includes that anthropogenic, have carbon backbone structure, authorized in European Union, and defined maximum residue limit (MRL). Then, were selected according their physicochemical structural properties, MRL main food commodities, standard price...
