TL;DR: All hazard ratio values reported for PFOS and perfluorooctanoate (PFOA) were less than unity, suggesting that the detected levels would not cause any immediate health effects to the people in Taihu Lake region through the consumption of shrimps and fish.

TL;DR: In this paper, the authors reviewed the research published in the last decade on the global occurrence and distribution of per-and polyfluoroalkyl substances (PFAS) in the aquatic environment and the evolving global regulatory responses to manage and mitigate the adverse human health risks posed by PFAS.

TL;DR: This study significantly expands the understanding that multiple HBGAs are expressed in oyster, mussel, and clam gastrointestinal tissues, which could be the major mechanism of bioaccumulation of NoVs by these bivalves.

TL;DR: The results show that resuspension processes of dredged harbour sediments may induce both a release of Cd, Cu and Pb which are bioavailable for larvae (levels of bioaccumulation depending on the species) and biological perturbations, i.e. abnormal development in C. gigas and P. lividus larvae for the more contaminated sediments and growth inhibition in all three larvae for slightly contaminated sediment.

TL;DR: By an in vitro methylation experiment with two axenic cultures ofCoprinus comatus and Coprinus radians, it is shown for the first time that these saprophytic macromycetes are able to methyl ate mercury.
Abstract: The terrestrial biogeochemical cycle of mercury between humus and fungi was investigated in a mercury-contaminated former mining area of Germany. We used a variable volume extraction procedure and aqueous sodium boron tetraethyl derivatization to determine accurately and precisely methylmercury bioconcentration factors for fungi. The methylmercury and total mercury content for fungi carpophores ranged from 0.08 to 7.94 μg/g of Hg as methylmercury and from 6.2 to 144.0 μg/g of inorganic Hg, respectively. The levels in humus material were between 0.01 and 0.09 μg/g of Hg as methylmercury and 15.8 and 140.2 μg/g of inorganic Hg, respectively. The bioconcentration factors obtained are generally lower than 1 for total mercury and between 3.0 and 199.0 for methylmercury. By an in vitro methylation experiment with two axenic cultures of Coprinus comatus and Coprinus radians, we could show for the first time that these saprophytic macromycetes are able to methyl ate mercury.
