Summary: The present study assessed the bioaccumulation of Cu, Zn, Pb, and Cr in fish species from Pulicat Lake in southeast India. The study found variations in the accumulation patterns of metals in sediment, water, and fish samples. Although some muscle samples exceeded the safe limit for Cu and Cr concentrations, the estimated daily intake remained within the standard reference dose, indicating the safety of consuming fish muscle tissues.

Summary: This study reviewed the accumulation and distribution patterns of heavy metals in freshwater fish in nine basins of China from 2010 to 2020 and assessed their health risks. The results showed that the pollution level of heavy metals in Chinese freshwater fish is at an intermediate level internationally. The concentration of heavy metals in artificially farmed freshwater fish is higher than that in wild fish, and the noncarcinogenic risks are higher for children.

Summary: This study investigated the concentrations of heavy metals in carp-farming water and muscle in three major fish farms in Mazandaran Province, Iran. The results showed that the water concentrations of all metals were within permissible limits. The concentrations of heavy metals in the muscle of different carp species were also relatively low, indicating that consuming farmed carp products poses minimal health risks to humans.

Summary: The present study investigated the levels of heavy metals in the tissues of two commonly consumed fish species in Ghana, with results showing accumulation of heavy metals in all analyzed tissues. The accumulation was higher in the liver and gills compared to the muscles, and the catfish had generally higher metal bioaccumulation than the tilapia. However, all metal levels were below the maximum permissible limits set by FAO/WHO, indicating no potential health risk to consumers.

Summary: The study examined the levels of radioactivity and heavy metal contamination in dried fish samples from Chennai, Tamil Nadu. The results showed high concentrations of heavy metals, particularly Pb and Cd, which exceeded the permissible limits set by WHO. The study also found that the consumption of certain fish species could lead to radiation exposure above the recommended limit, as well as increased cancer risk due to the contamination.

Summary: The study found that levels of Fe, Pb, and Mn in the water of the Nile River in the Cairo region exceeded the allowed limits, while Cu and Zn levels were within limits. In fish muscle, Fe and Cu levels were within permissible limits, but Mn, Zn, and Pb exceeded the limits. The study also highlighted the importance of monitoring heavy metal concentrations in aquatic ecosystems and the potential health risks posed by certain metals like Pb to habitual fish eaters.

Summary: The toxic discharge of heavy metals into the water affects both the aquatic ecosystem and the human population interacting with it. It is important to conduct studies to determine the level of heavy metal pollution in order to better control and manage the pollution of aquatic ecosystems. This study assessed heavy metal contamination in fish and its associated health risk to the population around the Tarukri Drain, Punjab, Pakistan. The results showed that heavy metal contaminations in both fish species were within the permissible limits recommended by the World Health Organization (WHO).

Summary: Just recently, the presence of heavy metals in aquatic animals, particularly fishes, has been detected, leading to the need for a method to assess the health risks for humans who consume these contaminated fishes. The present study aimed to assess the health risk associated with the consumption of four heavy metals (arsenic, cadmium, lead, and copper) in three main edible fishes caught from Gorgan bay. The results indicate that the heavy metals found in Gorgan bay do not pose serious risks to consumer health, although there were some exceedances of acceptable values for target cancer risk.

Summary: Understanding habitat use and reproductive biology of invasive species is crucial for predicting invasions and developing management plans. The study on rudd in the upper Niagara River revealed that emergent vegetation is the most important habitat factor associated with the presence of age-0 rudd, and their presence decreases as distance to the nearest wetland increases. The findings can be utilized to create predictive models of rudd invasion and guide early detection programs.

Summary: This study investigates the physicochemical properties and heavy metal variations in sludge from sewage treatment plants in industrial and non-industrial cities in Haryana, India. The results show that the sludge from industrial sites has higher concentrations of Cd, Ni, and Cr, and poses a higher ecological risk compared to sludge from non-industrial sites. pH, total carbon, and phosphorus are important factors controlling the binding and removal of heavy metals in sludge.

Summary: Concentrations of heavy metals in Tilapia spp. from Calapan City, Philippines were assessed. The study found that Cd concentrations in all parts of Tilapia exceeded the FAO/WHO limits, with the highest concentration in the fins. Other heavy metals such as Cu, Pb, Mn, Hg, and Zn also exceeded the limits in certain parts of the fish.

Summary: The study focused on examining the concentrations of Cd and three divalent nutrients in locally grown rice grains from Hunan and Guangdong Provinces in China. The research found that there were consistent correlations between Cu, Zn, and Mn concentrations, but a lack of correlation between Cd and Zn in the rice grains. Additionally, the bioaccessibility analysis showed that the bioaccessibility of Cd, Mn, and Zn in the gastrointestinal fractions was significantly lower than that in the gastric fractions.

Summary: The study investigated the distribution of six potential toxic metals in water-sediment-submerged macrophyte systems in six shallow lakes in Changsha City, Central China. Vallisneria natans (Lour.) Hara was found to have the highest accumulation of metals, with the highest bioaccumulation factor (BAF) for Zn. The results suggest that native submerged macrophytes, especially V. natans, show potential for removing PTMs from urban shallow lakes.

Summary: Fe(III)-chitosan and Fe(III)-chitosan-CTAB composites were prepared and used for As(V) adsorption. Fe(III)-chitosan-CTAB showed higher adsorption efficiency. The adsorption kinetics fitted the pseudo-second-order model, while the adsorption isotherm fitted the Freundlich model. Both electrostatic attraction and surface complexation mechanisms played important roles in the adsorption process.

Summary: The aim of this study was to investigate the effect of thiol species on the high cadmium tolerance of spinach and provide information for improving soil utilization. The results showed that as cadmium stress increased, the cadmium concentrations in spinach tissues also increased. Glutathione (GSH) and phytochelatins (PCs) played important roles in response to cadmium stress. Negative correlations were observed between GSH and cadmium concentrations in roots, as well as between changes in PC3 and concentrations of cadmium in leaves. Thiol production can occur in different tissues of spinach, while the shoots mainly serve as a transport tissue for GSH.

Summary: Arsenite (As(III)) is the most toxic and soluble form of arsenic in flooded paddy fields, leading to higher accumulation of arsenic in rice compared to other crops. This study found that inoculating rice plants with As(III)-oxidizing bacteria and supplementing additional phosphate can accelerate the conversion of As(III) to less toxic arsenate (As(V)) and restrict the uptake and translocation of arsenic, thereby mitigating arsenic toxicity to rice plants.

Summary: This study investigated the bioaccumulation, biotransformation, and detoxification of inorganic arsenic (iAs) in the liver of yellow catfish (Tachysurus fulvidraco) under dietary exposure to two iAs forms (arsenate (AsV) and arsenite (AsIII)). The results showed that both AsV and AsIII significantly accumulated in the fish, and the detoxification of iAs depended on arsenic methylation and the level of antioxidants. Both reduction and oxidation processes of iAs were found, and low toxicity intermediates were identified.

Summary: Porous carbon nitride/titanium dioxide nanosheets modified by carbon quantum dots (CQDs) exhibited excellent photocatalytic performance for tetracycline (TC) degradation. The enhanced activity was attributed to the expanded absorption range and inhibited electron-hole recombination by the heterogeneous structure.
