Summary: The study found that the levels of Cd and Pb in the sediments of Chalan beel exceeded the world normal averages, while the levels of Ni, Zn, Mn, and Cu were below the normal averages. Cd, Pb, and Ni showed significant enrichment in the sediments, with Cd and Pb posing potential ecological risks. The presence of elevated levels of Cd and Pb in the sediments might be attributed to anthropogenic activities like discharged dyes from nearby handloom dyeing factories.

Summary: This research assessed the presence, sources, contamination status, ecological risk, and human health risk of heavy metals in soil and sediments of a used-automobile spare part market in Nigeria. The study found that human activities contributed to high concentrations of heavy metals, while geological factors also influenced the levels of certain metals. The anthropogenically sourced heavy metals showed moderate to high enrichment/contamination, posing potential risks to human health and the ecosystem.

Summary: The study found that the concentrations of Cr, Ni, Zn, and Pb in South China Sea sediments are significantly positively correlated with fine-sized fractions and TOC, while the concentration of As is not positively correlated with other metals. The relatively positive correlations of Cd with various elements suggest it comes from different sources.

Summary: Heavy metals in reservoir sediments were analyzed to assess pollution levels and potential risks to water supply safety. The concentration of heavy metals increased in the sediments, with certain metals posing high risks in the main reservoir area. Continuous monitoring showed that heavy metal concentrations in the bottom water exceeded the environmental quality standard, indicating a potential risk of release into the overlying water. This study is of great significance for protecting drinking water safety and human health.

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: The pollution characteristics of size-segregated particles and metal elements in the atmosphere in 2016 were investigated following the release of the Chinese Air Pollution Prevention Action Plan in 2013. It was found that the composition of coarse particles is as important as that of fine particles when comparing pollution levels in 2016 to 2013. Additionally, the size distributions of particle mass concentrations were bimodal, with an increase in fine particle proportion as pollution levels elevated.

Summary: This study investigated heavy metal concentrations in sediments from the Parnaiba River Delta in Brazil, using multivariate statistical analysis and geochemical indices to assess pollution levels and ecological risks. Results showed lower heavy metal concentrations relative to Brazilian regulatory limits, indicating minimal enrichment of metals and low potential ecological risk. The study confirmed the pristine conditions of the protected area in the Parnaiba Delta, with the exception of the Igaracu channel near Parnaiba city.

Summary: An improved EF model integrating stochastic mathematical methods and geochemical baselines was successfully applied to evaluate and predict HM pollution in sediments collected from Poyang Lake, the largest freshwater lake in China. The model revealed slight enrichment of multiple HMs in the sediments, with Cd requiring more attention considering its dominant contribution to comprehensive pollution. Evaluation results of the improved EF model were more accurate, comprehensive, and reliable compared to conventional methods, indicating its potential for optimizing control measures for HM pollution.

Summary: This study aimed to assess the occurrence, spatial patterns, and potential sources of heavy metals (HM) in the sediments of the Astore River basin in northern Pakistan. The results showed that iron (Fe) and cadmium (Cd) had the highest and lowest concentrations, respectively, while manganese (Mn) contributed the most to pollution and Cd had the highest potential ecological impact. The sediments were classified as low to moderately contaminated, with Deosai valley identified as the zone of concern for management.

Summary: The study found that the average concentrations of six heavy metals in the sediment of the lower Meghna River estuary were ranked in descending order of iron (Fe), zinc (Zn), lead (Pb), chromium (Cr), copper (Cu), and cadmium (Cd). The geo-accumulation, contamination, and pollution load indexes indicated that the estuary was not contaminated by Fe, Zn, Pb, Cr, and Cu. There was a significant correlation between sediment grain size and the association of iron (Fe) and lead (Pb), but no significant correlation was found between other metals and grain size.

Summary: The analysis of trace metals in sediments of the Laptev and East Siberian Seas showed high concentrations of Cr, Zn, Ni, Cu, As, and Cd, with the increased Cd concentration possibly stemming from the highly productive waters of the Bering Sea. Contamination indices revealed no contamination by Cr, Ni, Cu, Zn, Pb, and Cd at any sampling locations, but slight As enrichment was observed.

Summary: The study of urban soils in Santiago de Compostela, Spain, revealed that the soils are mostly coarse textured, acidic, and have moderate to high organic matter content. The most abundant exchangeable cation in these urban soils is Ca, and overall, they do not exhibit common features of other urban soils such as alkalinity or high bulk density. The composition of these urban soils is similar to their natural counterparts in the region, highlighting the importance of conserving these soils with a low degree of artificialization for providing ecosystem services.

Summary: The study revealed the presence of inorganic pollutants such as Cu, Pb, Zn, Ni, Cr, and As in urban soils in Santiago de Compostela, Spain. While the concentrations were higher than regional backgrounds, they did not classify the soils as contaminated according to Spanish regulations, with most soils showing low to moderate pollution levels. The correlation between trace elements and their distribution in different land uses and parent materials was also observed.

Summary: Research on biosorption of organic dyes using composts showed that the sorption kinetics differ among different dyes, with BV10 having slow sorption rates while DB151 had faster rates. The sorption capacity was higher at lower pH and with increased salinity, and the Langmuir model adequately described the equilibrium sorption of dyes on composts.

Summary: The study indicates that there is high variability in microbiological properties among different land uses in urban soils, with soil organic matter content playing a significant role in microbial activity. Bacterial abundance is higher in urban grasslands, while fungal community composition is less affected by land use and more influenced by soil pH.

Summary: Compost from pine bark has shown effective adsorption for different classes of textile dyes. The adsorption capacity was higher for Basic Violet 10 (BV10) than for Direct Blue 151 (DB151) in batch conditions, and competition reduced the uptake of both dyes. Furthermore, the presence of both dyes in solution decreased their affinities in column tests. The column biosorbent could be effectively regenerated using ethanol.

Summary: This study evaluated the composition and diversity of fungal and bacterial communities in 40 soil samples collected from 10 urban allotment garden areas in Santiago de Compostela, Spain. The richness of microbial communities in these urban gardens was comparable to that of soils from other urban land-use categories with lower anthropogenic influence. Soil properties and geographical distances had minimal impact on the microbial communities. Network analysis showed that microbial associations formed small modules and frequently remained unconnected. These findings highlight the potential implications of anthropogenic activity on soil health and ecosystem functionality.
