Summary: This study investigated the concentration of nine heavy metals in Oreochromis niloticus and Ipomoea aquatica in Agodi reservoir, Nigeria. The results showed that the metals accumulated more in O. niloticus than in I. aquatica. Most of the examined metals exceeded the safety limit, and O. niloticus had lower tolerance for heavy metals. Additionally, metal concentration and ecological risk quotient were higher in the wet season for O. niloticus.

Summary: In this study, mercapto-grafted palygorskite (MPal) was synthesized to improve the performance of palygorskite (Pal) for in situ immobilization of heavy metal-contaminated soil. Field application results in northern China showed that MPal had better immobilization effects than Pal and improved the soil biological activity.

Summary: Mercury is a toxic metal that easily accumulates in organisms and spreads through the food chain. The concentration of mercury in Scomber colias has significantly decreased over the past few decades, possibly due to environmental regulations and measures to reduce mercury emissions. Additionally, historical collections of biological specimens are valuable sources of information for monitoring the effectiveness of legislative measures on the environment.

Summary: Contaminated sites, especially in China, have become a significant focus of research on heavy metal pollution assessment and remediation methods. China and the USA are leading countries in related research, with a particular emphasis on mining areas and industrial zones. Cd and Pb are the most studied heavy metals, with more severe pollution observed in southeast China than in the northwest.

Summary: The study analyzed the pollution characteristics and sources of heavy metal elements in the Zhundong mining area in Xinjiang for the first time, as well as evaluating the health risks and influencing factors using Monte Carlo simulation. Results showed that coal combustion, transportation, and atmospheric dust were significant sources of heavy metal pollution in the area. The research contributes to better soil management, remediation, and pollution control in Xinjiang's mining areas.

Summary: The study investigated temporal patterns of THg and MeHg concentrations in a common watersnake species and evaluated relationships among different tissue types. The results showed significant declines in THg and MeHg concentrations from the 1980s to 2019, indicating a gradual attenuation of contaminants in watersnakes.

Summary: This study investigates an efficient nondestructive detection method for mercury, cadmium, and copper in soils using terahertz spectroscopy. Regression equations are established between heavy metal contents and absorption coefficients, and the pollution type and level are simultaneously detected. Probabilistic neural network and random forest models validate the qualitative detection, while a backpropagation neural network and an extreme learning machine predict the heavy metal content. Results show that terahertz spectroscopy has good qualitative and quantitative detection ability for heavy metal pollutants in soil.

Summary: Galveston Bay is an anthropogenic-influenced estuary with high concentrations of heavy metals in sediment, especially in the eastern bay. Temporal variations in sediment metal concentrations are primarily controlled by river discharge, with stable levels of some metals in the 20th century and increasing levels of others in recent years.

Summary: Seasonal tissue concentrations of heavy metals, antioxidant enzymes, immunological components, and water quality parameters were investigated throughout 1 year in the ark clam, Barbatia decussate, from the coast of Lengeh port, Iran. The results showed a seasonal pattern in the accumulation of heavy metals, with maximum levels in winter for the ark clam. Furthermore, the antioxidant defense and immunity of the ark clam are reduced during winter, making it susceptible to diseases.

Summary: Risk assessment of heavy metals is critical in controlling and preventing risks of foodborne diseases. Fish can be used as bioindicators for exposure to potential toxic elements (PTEs), which can represent potential risks for humans. The study collected data on PTEs in fish from different fishery regions in Iran and used Monte Carlo simulation to assess health risks. The results showed that mercury intake from fish in all regions exceeded safe levels for children, and consumers of fish from the southern sea were at risk of mercury adverse health effects. The study also highlighted the high carcinogenic risk of cadmium in fish from all regions. Overall, the consumption of fish in Iran may pose health complexities for consumers, especially infants and pregnant women.

Summary: The study reveals that both invasive and native plants exhibit high tolerance to heavy metals, but under copper and cadmium treatments, the invasive plant shows a higher tolerance index and phenotypic plasticity, enhancing its competitive ability. This suggests that high phenotypic plasticity may be an important tolerance strategy for invasive plants, particularly in habitats with high levels of heavy metal pollution.
