Microcystins (MCs) are hepatotoxins harmful for animal and human health. The most toxic type between them is MC-LR whose presence has been investigated in different reservoirs all around the world. In this work microcystins were monitored in spring and summer in water and mussels of two Sardinia lagoons: Cabras and Calich lagoons. A Solid Phase Extraction method was developed to clean and concentrate samples before the Enzyme Linked Immunosorbent Assay (ELISA) and the following Mass Spectrometry detection. MCs presence was detected using the screening ELISA test in both lagoons. MCs peak was revealed in July for water and mussels belonging to Cabras lagoon (0.75 ± 0.07 ng/L in water and 0.12 ± 0.04 ng/g ww in mussels). In water of Calich lagoon there was a constant trend in the concentration of MCs during the considered months, while there was a MCs peak in July (0.6 ± 0.5 ng/g ww) in mussels. The following LC-MS/MS analysis did not reveal MC-LR presence in all analyzed samples. These results can be useful to enrich knowledge on public health and consumer's safeguard.

Biofouling is a common phenomenon caused by waterborne organisms such as bacteria, diatoms, mussels, barnacles, algae, etc., accumulating on the surfaces of engineering structures submerged under water. This leads to corrosion of such surfaces and decreases their moving efficiency.

The evaluation of nanoplastics bioaccumulation in living organisms is still considered an emerging challenge, especially as global plastic production continues to grow, posing a significant threat to humans, animals, and the environment. The goal of this work is to advance the development of standardized methods for reliable biomonitoring in the future. It is crucial to employ sensitive techniques that can detect and measure nanoplastics effectively, while ensuring minimal impact on the environment.

Marine mucilage disasters, primarily caused by global warming and marine pollution, threaten food security and the sustainability of marine food resources. This study assessed the microbial risks to public health in common sole, deep-water rose shrimp, European anchovy, Atlantic horse mackerel and Mediterranean mussel following the mucilage disaster in the Sea of Marmara in 2021. The total viable count, total Enterobacteriaceae count and the presence of Escherichia coli O157:H7, Salmonella spp.

The reproduction of mussels occurs within the water column, and if gametogenesis is successful, gametes are exposed to the surrounding contaminants. Nanoplastics and other emerging contaminants have been gaining vast attention; however, their effects on the reproductive tissues of mussels with sex differentiation are scarce. Here, the effects of polystyrene nanoparticles (50 nm; 10 µg/L), the cytotoxic drug 5-fluorouracil (10 ng/L), and a mixture of the two were evaluated in the gonads of Mytilus galloprovincialis after a 21-day exposure for a multi-biomarker assessment, and after 28 days for the accumulation of nanoplastics.

The effectiveness of magnetic nanoparticles in removing pollutants during water treatment is well established, but their introduction into aquatic ecosystems raises significant toxicity concerns. This study investigates the histological and physiological effects of zinc ferrite magnetic nanoparticles (ZnFeOMNPs) on the Mediterranean mussel (Mytilus galloprovincialis) and examines the impact of concurrent exposure to these nanoparticles and the insecticide thiomethoxam (TMX). Mussels were exposed to nominal concentrations of ZnFeOMNPs (1, 10, 100 mg/L) both individually and with TMX.
