Summary: This study investigated the concentrations and abundance of 11 antibiotics in water, sediment, and various aquatic organisms in the Pearl River, South China. The results showed that the bioaccumulation of antibiotics was positively correlated with their ionized form. Sediment ingestion was found to be a potential route of antibiotic exposure, as indicated by higher bioaccumulation in benthic organisms compared to fish. Additionally, only ciprofloxacin exhibited significant trophic magnification, suggesting the importance of metabolic biotransformation in driving the biomagnification of antibiotics.

Summary: This study investigated the spatial patterns in arsenic (As) bioaccumulation in freshwater systems in Ontario, Canada, using a dataset of 3200 fish across 152 waterbodies. The results showed that arsenic concentrations were generally low, but higher in fish from northern coastal rivers compared to landlocked sites. Arsenic concentrations were slightly associated with the proportion of pelagic carbon in a fish's diet, with variations among species and sites.

Summary: The study investigated the bioaccumulation behavior of D6 in rainbow trout and found that the depuration of D6 in fish was mainly through biotransformation in the fish body, leading to a lack of biomagnification. The bioaccumulation capacity of D6 was markedly less than many hydrophobic organochlorines based on comparisons with similar profiles for other chemicals.

Summary: This study investigated the levels and trophodynamic features of arsenic (As) and cadmium (Cd), and their potential human health risks in marine ecosystems. Results showed significant variations in As and Cd concentrations between fish and invertebrates at different trophic levels. The biomagnification of As and Cd in invertebrates through trophic transfer was hidden in overall evaluations of toxic element bioaccumulation in marine fauna. The non-carcinogenic health risk associated with As and Cd from consuming invertebrates was higher than that from fish, especially for children.

Summary: A study investigated the concentrations of 27 metals and elements in the tissues of 28 demersal and pelagic marine fish species from the Eastern Mediterranean Sea. The research found that the majority of elements had higher accumulation concentrations in the gills, liver, and scales, while the muscle had the lowest. Pelagic fish tended to accumulate higher concentrations of elements compared to demersal fish.

Summary: This study investigated the levels, distribution, sources, ecological, and human health risks of hormones and phenolic endocrine disrupting chemicals in the mariculture areas of the Pearl River Delta in China. The research found that contaminant levels were higher in shellfish compared to fish, and that the pollution was a result of coastal anthropogenic discharges and mariculture activities. The hazard quotient values of the contaminants indicated no immediate human health risk. This study is significant for scientific mariculture management, land-based pollution control, ecosystem protection, and safeguarding human health.

Summary: Mercury is a highly toxic and mobile heavy metal that poses significant environmental and health risks. High concentrations of mercury were found in the environment, particularly in surface water, soil, sediments, and urban atmosphere. Seafood and vegetable consumption were associated with high health risks, while risks from soil and groundwater ingestion were relatively low.

Summary: Research found that larger fish have higher microplastic loads, but smaller fish have more translocated microplastics. There is no evidence of biomagnification of microplastics, with excretion of translocated particles or growth dilution possibly occurring instead of bioaccumulation.

Summary: We analyzed the concentrations of 40 PFAS in fish muscle biopsy and serum samples to investigate PFAS in an aquatic food web and its potential human health implications. We detected novel PFAS congeners in the muscle and serum of three fish species from the Detroit River (contaminated site) and St. Clair River (reference site). The biomagnification of PFOS was observed in both rivers, and the nonlethal sampling method showed potential for monitoring PFAS and understanding their ecological and human health impacts.

Summary: Mercury bioaccumulation in fish and scalp hair was assessed in fishing communities along the river Swat in Pakistan. Significant differences were found in mercury concentrations between upstream and downstream fish and scalp hair. Health problems in the fishing community were attributed to mercury accumulation from fish consumption.

Summary: This study investigated the bioconcentration, bioaccumulation, and biomagnification of metals in the aquacultured fish species seabass (Lateolabrax japonicus). The research found that the gill and stomach contents of the fish had higher levels of metal bioconcentration. The bioaccumulation factor showed that the gill and backbone accumulated the highest levels of zinc, while the viscera accumulated the highest levels of copper. The study also revealed efficient bioaccumulation from commercial feed and the fish's habitat. Health risk assessment indicated no adverse effects from consuming seabass.

Summary: This review discusses the occurrence of arsenic (As) in various aquatic habitats and the direct or indirect effects on different organisms, including bacteria, algae, phytoplankton, zooplankton, and higher trophic levels. Special emphasis is given to finfishes and shellfishes that are commonly consumed by humans. The review also provides an overview of commonly used detection methods for As and highlights the importance of using As metabolites as an indicator of human exposure. Furthermore, the integration of 'omics' approaches and advanced sequencing technologies is emphasized for global monitoring of the human gut microbiome and understanding the effects and consequences of As bioaccumulation.

Summary: This study investigated the effects of exposure to OCPs, PCBs, and microplastics on juvenile gilthead seabream, finding higher concentrations of pollutants in the liver compared to muscle, with variability in muscle levels between treatments and sampling periods. Furthermore, microplastics were found to be correlated with certain pollutant concentrations in the liver.

Summary: With the rapid economic development and population growth in China's coastal areas, heavy metal contamination in estuarine waters is becoming a more serious issue. This study monitored five heavy metals in the Pearl River estuaries from January to December 2020 and evaluated the ecological risks they pose to aquatic organisms. The results showed that the concentrations of As, Cu, Pb, Hg, and Zn in the estuaries met or exceeded water quality standards, with Cu and Zn posing elevated ecological risks to certain aquatic organisms. The Humen, Jiaomen, Hongqimen, and Hengmen estuaries had slightly higher heavy metal levels and ecological risks compared to other estuaries, while the Yamen estuary had the lowest levels.

Summary: This study proposed an effective risk assessment method for aquaculture to predict the bioaccumulation of pollutants in fish tissue based on water environment variables, aiming to safeguard China's food safety standards. The method can be extended to other aquaculture applications that require monitoring parameters to ensure quality and safety risk management.
