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 investigated the effects of key biological and environmental factors on three hepatic xenobiotic biomarkers and compared two pelagic species. The results showed sex-dependent activities of carboxylesterases in sardine, and reproductive activity and temperature significantly influenced carboxylesterases and glutathione S-transferase activities. In vitro experiments demonstrated that the pesticide dichlorvos could inhibit carboxylesterases activity up to 90%. This research highlights the importance of considering reproductive status, temperature, and sex in biomarker responses and suggests that anchovy may be a more suitable pelagic bio-indicator for pollution due to its higher sensitivity to dichlorvos and sex-independent biomarker responses.

Summary: The rapid urbanization and industrialization have led to heavy metal contamination in aquatic environments, posing a threat to ecosystems and human health. This study found that melatonin can effectively reduce cadmium accumulation in fish muscle and aid in the elimination of accumulated cadmium. Factors such as exposure duration, cadmium concentration, and melatonin play important roles in cadmium bioaccumulation and depuration in fish tissues.

Summary: Pacific herring, a key species in marine food webs, spawn on marine macroalgae in shallow nearshore areas. However, these areas are at high risk from oil spills, and herring embryos are highly susceptible to toxic effects from oil. The water-soluble components of crude oil disrupt the physiological functions of herring embryos' hearts, leading to heart failure and reduced fitness in the juveniles.

Summary: Chronic exposure to multiple pollutants can harm aquatic organisms and impact fishery activities along the Algerian coastline. The health of fish can be assessed using indicators such as hepatosomatic index, gonadosomatic index, and condition factor. The presence of toxic metals and polycyclic aromatic hydrocarbons in water and sediment explains the decline in fish health and fishery production. Histopathological damage in the liver and factor analysis further highlight the risks of exposure to biota or human populations.

Summary: The study focused on heavy metal pollution in the green vegetation of a suburban industrial area in Tuokexun County, Xinjiang, China. The results showed that the overall level of heavy metal pollution in the soil was minor, with mercury (Hg) being the most severe contamination, likely caused by human activities. The composition of heavy metal elements in trees was more stable compared to grass and shrubs, with varying concentrations across different vegetation. Shrubbery was found to be the most effective in heavy metal restoration, and there were disparities in heavy metal enrichment among different vegetation types.

Summary: Plastic pollution has significant environmental impacts, largely due to chemical additives. However, the behavior of plastic additives in marine environments is not well understood. A marine deployment experiment was conducted to investigate the effects of weathering on the extractables profile of four types of plastics in New Zealand over a period of nine months. The concentration of additives in polyethylene and oxo-degradable polyethylene was strongly influenced by artificial weathering, while polyamide 6 and polyethylene terephthalate showed minimal change. These findings emphasize the importance of considering leaching and weathering effects on plastic composition when assessing the potential impact and risk of plastic pollution in receiving environments.

Summary: Few studies have examined the impact of urbanization and meteorological events on microplastics discharged into the sea through rivers. Surface water samples were collected from two Lebanese rivers, with differing degrees of urbanization, during dry and wet periods. The results showed that the most industrialized river had a significantly higher abundance of microplastics compared to the less-industrialized river. There was also a correlation between particle contamination and the season at each site, with microplastic concentrations highest on the first day of the wet season. These findings highlight the importance of considering meteorological events in accurately assessing plastic pollution influx into coastal waters.

Summary: This study investigated the variability in phytoplankton functional structure using a trait-based approach and explored the relationship between species traits and environmental factors, as well as their impact on ecosystem functioning. The results revealed that morphological traits, temperature, and ammonia played a decisive role in the seasonal succession of phytoplankton species. It was found that certain traits favored higher biomass production but might hinder energy transfer efficiency. The strong correlation between environmental variables and phytoplankton functional structure supports the practical implementation of a trait-based approach in studying phytoplankton community dynamics under different environmental conditions.
