Ocean acidification (OA) is reported to entail a detrimental impact on calcifying organisms. Nevertheless, patellid limpets - P. caerulea, P.

Rare earth elements (REEs), including gadolinium (Gd), are increasingly released into the environment because of their widespread use in medical imaging, electronics, and renewable energy technologies. Despite growing concerns over their accumulation in soil ecosystems, the effects of Gd on terrestrial organisms are poorly understood. To address this gap, we evaluated the toxic effects of Gd on the soil organism Lumbricus terrestris at both the adult and juvenile stages.

We investigated the health conditions of the Mediterranean mussel Mytilus galloprovincialis recruited in the CO vents system of Castello Aragonese at Ischia Island (Mediterranean Sea). Individuals of M. galloprovincialis were sampled in three sites along the pH gradient (8.

Patella caerulea (Linnaeus, 1758) is a mollusc limpet species of the class Gastropoda. Endemic to the Mediterranean Sea, it is considered a keystone species due to its primary role in structuring and regulating the ecological balance of tidal and subtidal habitats. It is currently being used as a bioindicator to assess the environmental quality of coastal marine waters and as a model species to understand adaptation to ocean acidification.

The ubiquitous presence of water-soluble polymers (WSPs) in freshwater environments raises concerns regarding potential threats to aquatic organisms. This study investigated, for the first time, the effects of widely used WSPs -polyvinyl alcohol (PVA), polyvinylpyrrolidone (PVP), polyacrylic acid (PAA), and polyethylene glycol (PEG)- using a multi-level approach in the freshwater biological model Daphnia magna. This integrated assessment employed a suite of biomarkers, evaluation of swimming behaviour, and proteomic analysis to investigate the effects of three environmentally relevant concentrations (0.

The water-soluble polymers (WSPs) are widely used in many industrial applications and are present in several commonly used products due to their physical-chemical characteristics: as their name indicates, despite being synthetic polymers, they are able to solubilize in water. Because of this peculiar property, both the qualitative-quantitative evaluation in aquatic ecosystems and their potential (eco)toxicological effects have been neglected until now. The aim of this study was to evaluate the possible effects of three of the most widely used WSPs as polyacrylic acid (PAA), polyethylene glycol (PEG) and polyvinyl pyrrolidone (PVP) on the swimming behaviour of zebrafish (Danio rerio) embryos after the exposure to different concentrations (0.

This study aimed to assess the combined effects of ocean acidification (OA) and pollution to the polychaete Syllis prolifera inhabiting the CO vent system of the Castello Aragonese (Ischia Island, Italy). We investigated the basal activities of antioxidant enzymes in organisms from the acidified site and from an ambient-pH control site in two different periods of the year. Results showed a limited influence of acidified conditions on the functionality of the antioxidant system.
