Summary: The study evaluated the joint effects of lead (Pb), manganese (Mn), antimony (Sb), tin (Sn), and titanium (Ti) coexposure on children's IQ scores. Results showed that multi-metal exposures were associated with a decline in children's IQ scores, with interactions between certain metals influencing IQ levels.

Summary: Adequate intellectual abilities serve as a protective factor for psychosocial adjustments in chronic disorders. This study found that children with narcolepsy and high intellectual potential had lower perceptual reasoning index and fewer conduct disorders compared to controls, while children with narcolepsy and normal intellectual range reported more school difficulties.

Summary: Gallbladder cancer (GBC) is a deadly malignancy with limited treatment options. The role of arsenic (As) in GBC carcinogenesis is debated, and there are no data on As measurement in GBC samples. This pilot study measured As concentrations in GBC tissue samples compared to non-cancerous gallbladder (NCGB) samples and found higher levels of arsenic in GBC samples, suggesting a potential impact of arsenic on GBC and the need for further studies.

Summary: Heavy metals pose significant environmental pollution and health hazards. Novel biosensors utilizing nanotechnology have been designed to detect ultra-trace amounts of heavy metals effectively and efficiently. Aptamers and whole cells are important bio-functional nanomaterials utilized in the design of heavy metal biosensors.

Summary: The direct impact of mining activities on physicochemical and biological parameters in aquatic ecosystems increases the ecotoxicological risk of exposure to contaminants and pollutants. This study used a native and adapted floating aquatic macrophyte as a model organism to assess the environmental risk and its potential application in bioremediation of heavy metals in a gold mining area. The results showed significant bioconcentration of Cr, Pb, Cu, and Zn in the roots of the macrophyte, confirming its suitability for use in rhizofiltration. H. ranunculoides also demonstrated high potential for phytoextraction of arsenic, an essential requirement for plants in bioremediation programs.

Summary: In this study, SBSG was found to have protective effects against arsenic-induced cell damage by reducing extracellular lactate dehydrogenase activity and influencing mitochondrial membrane potential, reactive oxygen species level, malondialdehyde content, and anti-oxidative enzyme activity. Additionally, SBSG promoted nitric oxide production and inhibited the activation of the JNK signaling pathway to protect against arsenic-induced damage. This study provides new insights into the detoxification effects of SBSG on heavy metals in the intestine and suggests that SBSG can be used as a natural antioxidant to combat heavy metal toxicity.

Summary: The study found that levels of mercury, cadmium, and lead in green mussels and oysters from coastal provinces of Manila Bay were below regulatory limits, posing no health risks to consumers. Further risk assessments on other fishery commodities in the area are recommended to ensure consumer safety.

Summary: The study investigates the microbial activity of natural ferric ochres at abandoned mining sites and its impact on the risk of contamination spread, highlighting the role of various aspergilli strains in affecting mobility and bioavailability of coprecipitated contaminants. Results show the remarkable bioextraction and environmental capability of Aspergillus niger strain in decreasing pH and extracting potentially toxic elements from natural ochres.

Summary: This research investigated the effects of toxic metals on tomato plants grown under wastewater irrigation, as well as the potential consequences of consuming these plants by both domestic and foreign individuals. The study found that using wastewater for irrigation led to a decrease in soil and tomato plant nutrients, while significantly increasing the concentration of toxic metals. Tomato plants grown with untreated wastewater may pose a greater danger to human health and should not be grown as a crop for human consumption.

Summary: The study investigates the metal(loid) content in Concholepas concholepas in a coastal environmental sacrifice zone in Chile to assess human-health risks. The results indicate that Cu and Cd levels exceed safety limits, and the intake of As is comparatively high. Consuming C. concholepas may pose a moderate carcinogenic risk.

Summary: This study assessed the health risks posed by selected metals in cultured and wild Crassostrea madrasensis in Sri Lanka. The concentrations of metals in the oysters varied on a monthly basis, with significant variations between cultured and wild oysters for zinc and copper. While the concentrations of most metals were below international standards, lead, cadmium, arsenic, and zinc exceeded the limits. Weekly intake of mercury, copper, iron, and zinc from C. madrasensis did not exceed the provisional tolerable intake, but cadmium intake exceeded the limit, indicating potential carcinogenic effects for long-term consumption.

Summary: This study measured the concentrations of Hg, As, Ni, Cd, and Pb in six fish species commonly consumed in Kendari and assessed the potential human health risk. The results showed that mercury is the only metal that poses a potential hazard, while Chanos chanos does not pose a toxicological risk.

Summary: This study investigated the concentrations of heavy metals in the surface sediments of the Mae Chaem River in Thailand. The levels of heavy metals exceeded the standard levels in Thailand, with the primary sources of contamination being residential settlements and agricultural areas. The study also assessed the risk of exposure to heavy-metalbound sediments for children and adults, finding that the risk was low overall but highest for As and Cr in terms of children's exposure.
