Emergent pollutants, escalating pressures: GenX effects on mussels in a changing environment.

Per- and polyfluoroalkyl substances (PFAS) are persistent pollutants with rising concern due to their stability and toxicity. The production of novel PFAS with shorter carbon chains in the environment raises concerns related to their stability and their potential toxicity in organisms. This study examines the effects of hexafluoropropylene oxide dimer acid ammonium (HFPO-DA, or GenX) on the marine mussel Mytilus galloprovincialis under different salinity conditions.

What do emerging PFAS tell us that the classic ones did not? Insights from in vitro assays.

Per- and polyfluoroalkyl substances (PFAS) are synthetic chemicals that are recognized for their environmental persistence and potential toxicity. As regulatory pressure increases on legacy PFAS, emerging alternatives are being increasingly used. However, their environmental toxicological profiles remain poorly understood.

Invasive blue vs. local Green: analysis of substrate preference of two crab species, Callinectes sapidus and Carcinus aestuarii.

Introduced primarily via ballast waters, the Atlantic Blue Crab, Callinectes sapidus, has spread throughout the Mediterranean Sea exhibiting a highly invasive behaviour. In introduced ecosystems it is posing a threat to local species and economic activities. This study compares, for the first time, habitat preference of C.
