Summary: This study explores the effects of physical and chemical factors and heavy metals on microbial diversity, community structure, and functions of bacterial and fungal communities in a black-odorous river in Wuhu, China. The results show that urbanization has led to eutrophication in river ecosystems, with heavy metals frequently observed. The influence of physical and chemical factors and heavy metals on microbial variation varies between bacterial and fungal communities.

Summary: This study investigated the nematode communities in coastal waters in Bohai Bay, China, assessing the environmental quality using various indices. The results showed variations in environmental quality at different stations, with metal concentrations being more influential than other variables in explaining nematode diversity.

Summary: During the XXXIII Antarctic expedition, researchers conducted an investigation in Terra Nova bay and found that the colony of Adelie penguins had a more significant impact on the meiobenthic assemblages compared to the human activities at the Mario Zucchelli Research Station. This suggests that the chronic impact of the penguin colonies may have stronger effects on the meiobenthos than human activities in the area.

Summary: A novel method using support vector machine (SVM) model was developed to predict heavy metal concentration in lake water, incorporating low-cost nutrients and physicochemical indicators as input variables. The study found that heavy metal concentrations in the lake water varied spatially and seasonally, with the highest levels during the medium-water period and the lowest during the dry season.

Summary: The study applied the Quality Ratio (QR) index in Sepetiba Bay to assess the ecological risk of sediments, integrating geochemical and microbiological parameters of in situ microbial community, and determining the concentrations of pollutants and enzymatic biomarkers for energy production. The QR was found to be an effective and efficient tool for segregating stations into internal and external sectors based on microbial and geochemical factors, demonstrating its accessibility and utility in ecological risk assessment.

Summary: This study found that the addition time of activated carbon during chicken manure composting can affect the mobility of heavy metals, with the addition of activated carbon during the thermophilic period effectively reducing the mobility of heavy metals. High-throughput sequencing analysis revealed the dominant and abundant bacterial communities in compost samples, mainly including Proteobacteria, Firmicutes, etc. Redundancy analysis showed the impact of dominant bacteria on the mobility of heavy metals in activated carbon amended compost.

Summary: This study evaluated the potential of vermicomposting in managing different ratios of coconut husk waste and cattle dung. The results showed that a ratio of 50:50 resulted in the lowest mortality and highest growth of earthworms. Vermicomposting improved the nutrient content and reduced the heavy metal content, producing mature and non-phytotoxic compost.

Summary: Activities at the Brazilian Antarctic Station may have a negative impact on the surrounding environment. Meiofauna was used to evaluate this impact, comparing an area possibly impacted by the station with a reference area. The study found that the differences in meiofauna community were mainly influenced by depth, indicating no anthropogenic impact.

Summary: Human activities can have negative impacts on the ecosystem health of semi-enclosed bays, particularly on the microbial communities that regulate biogeochemical cycles. This study analyzed sediment samples from a typical semi-enclosed bay in Guangdong, China and found that aquaculture activities were the primary source of potentially toxic elements such as copper, zinc, and lead. High-throughput sequencing revealed Proteobacteria as the dominant phylum in the sediments. Although there was no site-specific variation in microbial function, pollutant-specific variations were observed, with zinc and lead showing potential adverse effects on environmental information processing and arsenic exhibiting a negative correlation with metabolic function.

Summary: The spatial concentration of heavy metals (Mn, Ni, Cu, Co, Zn, Cd, and Pb) was studied in coastal areas of Palk Bay, India. Pollution indices were calculated to evaluate the metal pollution in water and sediment, which indicated moderate contamination of sediment due to anthropogenic activities. Cadmium concentrations were the highest and positively correlated with anthropogenic sources.

Summary: Mine tailings were analyzed for their chemical composition and microorganisms associated with them. The soil and water samples from different locations in an active artisanal gold mine were analyzed for physiochemical properties, heavy metal species, and their potential effects on human health. Heavy metal resistant bacteria (HMRB) were isolated and identified, and their potential for bioremediation was discussed. The presence of heavy metals in the mine tailings poses a high risk of cancer and other health effects, highlighting the importance of further study and potential remediation efforts.

Summary: Oil and petroleum products are common pollutants in the marine environment, posing challenges in interpreting pollution data. This study used gas chromatographic methods to determine hydrocarbon content, distribution, and sources in the Chernaya River, finding that autochthonous production is the main source, while oil and petroleum products rank third in importance.
