Summary: This study investigated the spatiotemporal patterns of groundwater heavy metals and the driving mechanism in a subtropical mangrove wetland in China. The results showed that the distribution of heavy metals varied seasonally along the transect, influenced by factors such as seawater-groundwater interactions, vegetation zonation, biogeochemical reactions, and anthropogenic activities. This research contributes to a better understanding of heavy metal behaviors in mangrove groundwater for sustainable management of mangrove wetlands.

Summary: This study examines the environmental legacy of aquaculture and industrial activities in mangrove rehabilitation areas using interdisciplinary approaches. The findings indicate an increase in mangrove coverage, but the presence of fecal bacteria communities and genes associated with pathogenicity, antibiotic resistance, and xenobiotic degradation. The study also reveals high nitrate concentration resulting from aquaculture waste and low to moderate heavy metal concentration due to the biofiltration role of mangroves. The conclusion highlights the importance of mangrove restoration in mitigating the environmental impact of human activities.

Summary: Groundwater is the main source of drinking water in urban areas worldwide, but the increasing presence of potentially toxic elements from various sources poses health risks. A study in Northern Mexico assessed the presence of these elements in groundwater and found that while most concentrations were below standards, the risk of cancer and harm to health from chromium consumption was considered unacceptable.

Summary: A novel yeast Geotrichum sp. CS-67 showed high tolerance to heavy metals and demonstrated efficient uptake and sequestration of Zn2+, Ni2+, and Cu2+. RNA-Seq analysis revealed differential expression of genes involved in heavy metal processing when under Zn2+ and Ni2+ stress.

Summary: The study revealed that Hg content in mangrove soils impacted by chlor-alkali plants exceeded local background levels by up to 180 times, posing high ecological risk while the daily average exposure for humans remained within tolerable levels recommended by the World Health Organization. However, the human health risk was deemed unacceptable in the estuary section closest to the plant, particularly for children.

Summary: This study evaluated the potential of mangrove plants in purifying polluted ecosystems. The results indicate that these plants are capable of storing metals in their tissues and reducing the risk of certain metals. Among them, Avicennia officinalis performed well in metal extraction.

Summary: Heavy metal pollution has become a serious issue in mangrove ecosystems, drawing attention to its impact on fungal communities. This study investigated the effects of heavy metals and organic matter fractions on fungal communities in mangrove sediments, finding that different heavy metals and organic matter fractions had varied effects on fungal genera. Organic matter-rich fungi may enhance the growth of heavy metal-rich fungi in mangrove sediments.

Summary: This study investigated the concentration and distribution of heavy metals in different mangrove sediments with different land-use patterns along the coast of Hainan island, China. The results showed that different land uses have different effects on heavy metal accumulation in mangrove sediments, and various activities such as mangrove farming and aquaculture ponds contribute to metal pollution.

Summary: Heavy metal pollution in groundwater is a significant concern for human health in the Indo-Gangetic Plain of India. Rice straw burning is a major issue due to the lack of feasible utilization options. This study explores the production of biochar from rice straw and its potential for removing manganese and arsenic from water.

Summary: Screening high Cd-accumulating plants and understanding the interactions between plants, rhizospheric microbes and Cd are important in developing microbe-assisted phytoremediation techniques for Cd-contaminated soils. In this study, the Cd tolerance and accumulation characteristics of three Phytolacca species were compared, and it was found that Phytolacca icosandra and P. polyandra had high Cd-accumulation capacities, making them potential candidates for phytoremediation. The study also revealed that the rhizospheric soil pH, available Cd concentration, and certain bacterial taxa were differentially altered in the presence of the Phytolacca plants, and these alterations influenced the Cd uptake by the plants.

Summary: This study found that mangrove reforestation promoted metal accumulation in sediments, but alleviated metal bioavailability. These changes were highly correlated with EPS and microbial composition, with the content of EPS positively correlated with metal accumulation and negatively correlated with metal bioavailability.

Summary: Groundwater is a vital natural resource that needs to be assessed for its quality. This study compared the performance of two water quality index models and investigated the presence of heavy metals in the groundwater in Ranchi city. The results showed that the Canadian Council of Ministers of the Environment Water Quality Index performed better and there were significant fluctuations in water levels. The health risks of heavy metals were also evaluated.

Summary: The study found that protein concentrations were significantly higher in Bruguiera gymnorrhiza, Kandelia obovata, and Rhizophora stylosa under heavy metal stress conditions, while Avicennia marina had remarkably high MDA content. Superoxide dismutase (SOD), peroxidase (POD), and catalase (CAT) levels were significantly elevated in A. marina, A. corniculatum, and B. gymnorrhiza. Principal component analysis indicated that POD, SOD, and MDA were major indices for response to heavy metal stress, with A. marina demonstrating higher tolerance compared to other species.
