Summary: The ingestion of microplastics affects the digestive enzyme activities of mussels, with polystyrene reducing certain carbohydrase activities and increasing others. High concentrations of microplastics can lead to a significant increase in total protease activity in mussels. Other digestive enzyme activities, such as laminarinase, lipases, and lipolytic esterases, remain unaffected by the presence of microplastics.

Summary: Participants in the coastal socio-economy of the Mediterranean Sea create pressures on marine ecosystems. This study suggests using Patella caerulea as a biosentinel for marine pollution and proposes combining environmental, toxicological, and genetic assessments. The study identified critical levels of metal contamination and observed the induction of antioxidant biomarkers in P. caerulea, highlighting its ability to adapt to pollution conditions. COI (mtDNA) analysis showed low discrimination between populations, indicating the role of marine currents in dispersal.

Summary: This study investigates the effects of three organic pollutants (chlorpyrifos, triphenyl phosphate, bisphenol A) on sea urchin larvae. The results show that chlorpyrifos has the highest toxicity, attributed to oxidative stress, modulation of acetylcholinesterase response, and reduced detoxification efficacy. The study also identifies glutathione reductase activity as a reliable biomarker of exposure for sea urchin early-life stages.

Summary: This study examined the changes in digestive physiology and nutritional reserve content of the Pacific pygmy octopus during early stages. The results showed that the transition from endogenous to exogenous feeding occurs between 6 and 8 days after hatching, and these findings are crucial for the development of effective feeding schemes for this species.

Summary: This study assessed the effects of different types and concentrations of glitter particles on Mytilus galloprovincialis and found a link between particle concentration and type, recovery rate, and oxidative stress in M. galloprovincialis. Smaller particles were more likely to be retained in the digestive tract and induced an increase in antioxidant defense. Certain types of glitter were found to crumble and shorten in length, leading to higher levels of oxidative stress biomarkers. Further research is needed to understand the toxic effects of glitter on aquatic organisms and quantify its proportion to other microplastics in the environment.

Summary: Ocean contamination by synthetic polymers can pose a risk to marine species due to leaching of chemical additives. This study evaluated the sub-lethal effects of plastic and rubber leachates on mussels, showing that different leachates can impact various biomarkers and enzyme activities. The mussel expert system (MES) categorized mussels' health status based on biomarker responses, indicating varying levels of stress from different leachates.

Summary: This study evaluated the effects of different feeding levels on the growth performance, digestive enzymes, body composition, metabolic enzymes, and antioxidant activities of juvenile Yangtze sturgeon. The research found that a feeding level of 3% body weight per day resulted in significantly higher weight gain rate and specific growth rate. Furthermore, higher feeding levels led to increased activities of digestive enzymes. Based on the results, the recommended feeding level for juvenile Yangtze sturgeon is 3% body weight per day at a temperature of 20.3±1.3°C.

Summary: This study evaluated the nutrient requirements of Macrobrachium acanthurus, specifically the interactions between protein and lipid-carbohydrate ratios in the diet and their effects on growth performance and enzyme activity. The results suggest that a diet containing 35% protein, 10% lipids, and 20% carbohydrates (L:C ratio 1:2) is optimal for growth performance and activity of digestive and antioxidant enzymes.

Summary: This study determines the activity concentrations of 137Cs in various seaweed and mussel samples from the North East Mediterranean Sea. The results show that seaweeds have approximately four times higher concentration of 137Cs compared to mussels, indicating a higher potential for bioaccumulation of 137Cs in seaweeds.

Summary: Plastic waste in the oceans is a growing problem for marine life. This study assessed the presence of microplastics (MPs) in the digestive tracts of Xyrichtys novacula fish from two different areas of Eivissa Island, as well as in the sediment of both areas. The results showed that over 80% of the fish samples had MPs in their gut, with the majority being fibers. Although there were more MPs in the sediment of the non-protected area, there were no significant differences in the number of MPs in the fish from both areas.

Summary: Metal and metallothionein in mixed zooplankton were studied to monitor metal availability in the Saronikos Gulf. Spatial and temporal variability of metal concentrations were observed, with higher levels in sites influenced by human pressures. Bioconcentration from water to zooplankton was found to be higher than other transfer pathways.

Results showed similar capacity for both types of particles to carry the pesticide, with mussels exposed to chlorpyrifos-loaded microplastics displaying similar or more pronounced biological effects after 21 days compared to those exposed to dissolved pesticide or pesticide-loaded natural organic particles.

Summary: During the summer of 2018 and winter of 2019, the occurrence and distribution of various pollutants were studied in surface waters of two sensitive areas in the Spanish coast. Among the 100 compounds analyzed, 63 organic contaminants were detected at concentrations of ng/L, including UV filters, plastic additives, synthetic musks, and other personal care products. The highest concentrations were found in certain compounds, such as octocrylene, homosalate, and ethylhexyl salicylate, indicating potential risks to aquatic organisms, especially during the summer.

Summary: This study provides an initial overview of the impact of organic chemical contaminants on the European eel and the potential sublethal effects of chemical pollution on pre-migrating eels in the Mar Menor coastal lagoon. The findings reveal that eels in this habitat are exposed to high levels of legacy organochlorine contaminants, banned pesticides, and emerging chemicals, and they show biomarker responses indicating genotoxic effects.
