Summary: An analysis of the hydrogeochemical compositions of shallow groundwater in the Hohhot Basin reveals the spatial characteristics of the environment and the distribution of high-arsenic water. The study identifies six different zones based on environmental characteristics, including redox condition, water recharge intensity, and cation exchange level. The results show that high-arsenic groundwater is mainly found in aquifers with strong reducing conditions, low surface water recharge intensity, and strong cation exchange conditions. The release of arsenic into groundwater is influenced by reductive dissolution of iron oxide, evaporation and concentration processes, and competition from phosphate in aquifers.

Summary: Coastal aquifers, especially in arid environments, are vulnerable to groundwater-seawater interaction. Kuwait's Bay groundwater is polluted due to anthropogenic activities like desalination plants and power plants. This study focused on nitrate contamination in groundwater samples collected from the southern part of Kuwait's Bay. Results showed high nitrate concentrations, mainly from contamination sources such as sewage leakage, seawater intrusion, chemical weathering, and denitrifying bacteria. The elevated nitrate levels pose health risks and may lead to eutrophication in the Bay. Proper management strategies are necessary to control nitrate pollution in groundwater.

Summary: The quality and availability of groundwater have been significantly affected by urbanization along the coasts due to climate change and changes in land use patterns. Dissolved organic carbon (DOC) in water is a major concern in current groundwater quality research. This study examined 68 groundwater samples and found that DOC in groundwater is influenced by DO, water level, and water temperature. High DOC levels were observed in urban regions, which correlated positively with dissolved inorganic ions. Various factors such as domestic wastewater, agricultural runoff, and local geology contribute to the DOC in groundwater. It was also found that groundwater chemistry is influenced by both aerobic and anaerobic conditions. Land use, geology, water level, and temperature are interrelated with the distribution of DOC in groundwater, with higher levels found in shallow groundwater around built-up and agricultural regions.

Summary: Sediments from the estuary of the Sibuti River in Malaysia were analyzed for metal fractionation. The study found that Pb, Cd, and Mn were the most mobile metals, while the majority of metals were associated with the residual fraction. The sequential extraction method revealed that Cd, Se, and Cr were dominantly associated with carbonate, reducible, and oxidizable fractions respectively. Factor analysis showed the regulation of Mn absorption by microorganisms and the role of organic matter in the absorption and settlement of Fe and Al-oxyhydroxides. The study also identified high contamination of Se, Co, Cu and Cd in the estuarine sediment, with Cu and Cr posing the maximum threat to the benthic community.
