Summary: Marine invertebrates, which make up over 90% of marine animal species, rely on lipids for cell membranes and energy reserves. The lipid composition directly impacts the nutritional value of commercial invertebrates. Despite detailed studies on lipid classes and fatty acids, data on lipidomes are limited, with only a few species investigated. The application of lipidomics in ecology, physiology, and nutritional value studies of marine invertebrates shows potential for further exploration.

Summary: Global seafood consumers are increasingly concerned about the safety, high quality, and hazard-free nature of seafood products. This study examined various Pakistani processing plants supplying the international market and investigated the metal content, contamination, and potential health risks of commercially important seafood species (fish, crustaceans, and cephalopods). The findings showed significant variations in metal concentrations among species, with Fe > Cu > Zn > Mn > Pb > Ni > Cd > Hg being the predominant metals. However, the contamination factor, pollution load index, and metal pollution index indicated negligible contamination levels in the seafood. According to the assessment of estimated daily intake, target hazard quotient, hazard index, and carcinogenic risk, the potential human health risks associated with the contaminated seafood were lower than perceived. In conclusion, seafood processing plants export products that meet international food safety standards and are safe for consumers worldwide.

Summary: This study aimed to identify the best UV-C combined treatments for ensuring the safety and quality of fish and meat products. For fish, the most effective treatments were UV-C combined with non-thermal atmospheric plasma (NTAP) and Verdad N6 with UV-C and vacuum packaging. An oxygen absorber was the best combined treatment for reducing lipid oxidation, protein oxidation, color, and hardness changes in fish. For meat products, nir-infrared heating (NIR-H) combined with UV-C and flash pasteurization (FP) showed the highest reduction in Gram-negative bacteria, while UV-C with FP was effective for reducing Gram-positive bacteria. UV-C combined technologies were cost-effective and ensured safety with minimal quality changes in fish and meat products.

Summary: This study aimed to characterize Escherichia coli (E. coli) and shiga toxin-producing E. coli (STEC) isolates from Brazilian beef to determine their heat resistance and the presence of the transmissible locus of stress tolerance (tLST). Results showed that 3 out of 22 STEC isolates were heat resistant, 12 were moderately resistant, and 7 were sensitive to heat treatments. Whole genome sequencing (WGS) analysis revealed that the heat-resistant isolates carried tLST genes with high similarity to the homeostasis module genes in E. coli. However, no stx genes associated with tLST-positive isolates were found, although virulence and resistance genes were detected in extraintestinal pathogenic E. coli (ExPEC).

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.
