Summary: This study aimed to evaluate the harmful effects of metal accumulation on Astyanax lacustris and their biochemical response when exposed to the metals contained in the Doce River water, Brazil. The study found that biochemical alterations were observed in the liver of A. lacustris, which were directly related to the high concentration of Al and Fe. In addition, seasonal effects of metal bioconcentration were only observed in the gills.

Summary: This study selected suitable biological models using geometric morphometrics analyses and analytical determinations of contaminants, and investigated the shell alterations of these models along a contamination gradient. The results showed that the reliability of morphometric responses was high for herbivorous and carnivorous species, while no significant differences in shell form were observed for filter-feeder species. Therefore, shell alterations on carnivorous gastropods could be potentially used as effective pollution biomarkers.

Summary: Non-invasive detection of biomarkers is important for early screening of diseases. This paper presents a numerical study of a tunable metasurface for mid-infrared detection using Germanium Antimony Telluride. The design involves using dissimilar materials and optimizing parameters to achieve high-quality resonances for trace analyte sensing. A practical device layout for biomarker detection applications is also proposed.

Summary: Microplastics have become a globally significant pollutant, and sandy beaches are particularly susceptible to plastic waste accumulation. Our understanding of microplastic distribution and contamination on beaches is currently inadequate. This study investigated the occurrence and characteristics of microplastics on 14 beaches along the coast of South China. The research revealed the extent and severity of microplastic pollution on South China's beaches and provided implications for future remediation measures.

Summary: The study found that exposure to specific agents can induce significant carcinogenic changes in hepatocytes, leading to the appearance of GST-P positive minifoci. Immunocytochemical staining of liver specimens revealed that GST-P was rapidly synthesized in all hepatocytes and excreted into bile after exposure to these agents. This suggests that GST-P positive single hepatocytes are formed after injury to the bile canaliculi by these agents.

Summary: Research has found that microplastics are common pollutants in the environment and pose challenges for their accurate identification in environmental samples. Failure to consider the potential cross-contamination during sampling and analysis could result in significant overestimation of microplastic presence. This review examines sources of cross-contamination, mitigation methods, and approaches to assessing and controlling this type of pollution based on available literature data.

Summary: The current technical standards for biodegradable polymers may not ensure their degradation in natural environments, especially in deep-sea ecosystems where plastic pollution is a concern. Therefore, there is an urgent need to revise these standards to consider more environmental parameters and conditions, and ensure global harmonization.

Summary: This review examines the relationship between PAH effects on marine biota, environmental health status, and potential human health risks from consuming contaminated seafood. It found that mussels are the most evaluated bioindicator species, and benzo(a)pyrene and phenanthrene are the most investigated PAHs. However, there is a lack of multidisciplinary assessments that consider the link between environmental PAH dynamics, effects on aquatic biota, and human health risks.

Summary: This study evaluated the burden of As, Hg, Pb, and Cd in 314 marine fishes from the Amazon Coast. The results showed higher Hg concentrations in reef-associated fish compared to demersal fish. The study also found correlations between As, Pb, and Cd, suggesting similar dispersion properties and bioaccumulation homology. The concentrations of As exceeded guidelines and legal limits in a majority of the examined species, while Cd, Hg, and Pb levels were generally low. The estimated daily intake of iAs, Hg, and Pb were found to pose potential non-carcinogenic health risks.

Summary: Anthropogenic activities are negatively impacting marine ecosystems, leading to habitat degradation, loss of biodiversity, and chemical pollution. Climate change exacerbates the toxic effects of pollutants and ecological risks. Contamination by metals and metalloids is particularly important, yet neglected due to the increasing focus on plastic pollution.

Summary: Children's vulnerability to chemical exposure is a concern due to the scarcity of studies on the presence of metal and metalloid in infant formulas. This study investigated the presence of several elements in infant formulas marketed in Brazil, with a focus on potential health risks for children. Arsenic was found to have potential health risk concerns for newborns or children. The study highlights the need for improved monitoring of infant formulas to prevent contamination by potentially toxic and carcinogenic elements.
