Article Synopsis
- - This study explores the levels and geographical differences of contaminants found in house dust across Europe, identifying over 1200 anthropogenic compounds using advanced techniques like mass spectrometry and suspect screening.
- - The research indicates that contaminant concentrations vary less than threefold within Europe, showing similarities with North American dust due to shared consumer products and materials.
- - It highlights geographical patterns, revealing that certain contaminants increased from north to south (like PAHs and chlorinated paraffins), whereas others, like biocides, decreased; it also emphasizes a significant risk from older, restricted contaminants, like DEHP and PCBs, despite limited toxicity data available for newer compounds.
Nation-wide monitoring campaign of 49 biocides and surfactants in surface waters and wastewaters.

December 2024
Despite their intensive use and their impact on ecosystems, biocides and surfactants are still poorly regulated and poorly monitored at large scale. In the frame of the revision of the national regulatory surveillance plan of surface waters, France planned in 2018 a monitoring campaign at national scale focused on these two types of substances of very emerging concern. Forty-nine contaminants (32 biocides and 17 surfactants) were investigated in surface water and sediment samples from 91 sampling sites, and in effluent and sludge samples of 7 wastewater treatment plants (WWTP), in mainland France and overseas regions.

The study comprised an investigation of the variability of captan DFR values and 14 days of DFR monitoring to assess kinetic modeling. A method combining solid-phase microextraction (SPME) gas chromatography and high-resolution mass spectrometry (GC-QTOF-MS) was developed for the quantification of captan residues from DFR aqueous extracts.

- Corticosteroids have been widely used in critical care for various conditions like respiratory distress, septic shock, and COVID-19, showing both benefits and risks.
- Key advantages include improved treatment outcomes, shorter hospital stays, and lower mortality rates, while significant adverse effects include hyperglycemia, hypertension, and increased infection risk.
- There is currently no thorough report on corticosteroid use in critical care, highlighting the need for better understanding and management of their use in therapy.
Article Synopsis
- A collaborative study involving 16 participants from nine European countries aimed to standardize the detection of environmental contaminants in fish samples using advanced analytical techniques like liquid chromatography and gas chromatography paired with high-resolution mass spectrometry.
- Participants analyzed freeze-dried fish samples from contaminated and reference sites, identifying a varying percentage of spiked compounds, and yielding unique features depending on the analytical method used.
- Results showed that inconsistencies in the identification of contaminants were largely influenced by differing data analysis methods among participants, highlighting the need for improved standardization in environmental screening practices.
