Levels and trends of synthetic musks in marine bivalves from French coastal areas

Organophosphate esters (OPEs) in the marine environment: Spatial distribution and profiles in French coastal bivalves

“…If the Nivelle and Elorn estuaries have been previously identified as sites under anthropogenic pressure (Aminot et al, 2021;Munschy et al, 2015), the case of the Etel estuary is peculiar, considering this is a site under the influence of a small rural catchment area, with no major city or particular industry, and for which the other contaminants followed in our surveys have always been low. The high TNBP concentrations detected in the above-mentioned low impacted sites warrant further research into the sources of this compound into coastal waters, as most of the industrial sources identified by Gao et al (2021) are unlikely here.…”

“…OPEs were the most abundant of all hydrophobic contaminants analysed in the same samples (for further details, refer to Aminot et al, 2021;Munschy et al, 2019Munschy et al, , 2015Munschy et al, , 2013, with concentrations decreasing as follows: OPEs > polycyclic musks (ng g −1 dw); followed by: perfluorocarboxylates (∑ C9-C14 PFCAs) > perfluorooctane sulfonate (PFOS) ∼ polybrominated diphenyl ethers (∑ 8 OSPAR PBDE congeners) > hexabromocyclododecane (hundreds of pg g −1 dw); followed by: nitromusks and alternative brominated flame retardants (BTBPE, DBDPE) tens of pg g −1 . OPEs are rarely reported alongside other hydrophobic contaminants in the literature on mollusc contamination.…”

Occurrence of Cosmetic Ingredients as an Anthropogenic Threat to the Seas and Oceans

“…preservatives or UV filters, due to the common occurrence in the tissues of marine organisms, they should be considered as hazardous anthropogenic pollutants. As in the case of UV filters, the frequency and concentration of these pollutants were found to depend on the population density and industrialization in the region [15,21].…”

“…The occurrence of musk fragrances in the tissues of aquatic organisms is already common. On the French coast, HHCB and AHTN were present in mussels and oysters at concentrations of 2.27 ng/g dw and 0.724 ng/g dw [21]. 70% of samples taken from the coast of Portugal were contaminated with musk smelling (AHTN) [15].…”

Cracked and Shucked: Gc-Apci-Ims-Hrms Facilitates Identification of Unknown Halogenated Organic Chemicals in French Marine Bivalves

“…Started in 2010, intertidal mollusks are collected at different coastal and estuarine sites along the French coast, including those under the influence of French major watersheds. The sought contaminants have constantly evolved including brominated and chlorinated flame retardants (FRs) (Munschy et al, 2015), per-and polyfluoroalkyl substances (PFASs) (Munschy et al, 2019), synthetic musks (Aminot et al, 2021), and organophosphate esters (Aminot et al, 2023) (flame retardants and plasticizers -OPEs). VeillePOP, which this work is a part of, aims to contribute to the improvement of knowledge on CEC, by providing essential spatial and temporal data on their presence in the marine environment and following the impact of regulations.…”
