Summary: This preliminary study aimed to investigate the short- and long-term effects of remedial dredging on metal contamination, dredging efficacy and ecological status of the Lower Passaic River. The short-term results showed effective reduction of heavy metal concentrations, although they increased in the water column, increasing the risk of bioaccumulation in aquatic biota. On the long-term, metal concentrations increased in surface sediments.

Summary: The study revealed that in the upstream of the Yellow River, most concentrations of heavy metals were lower than potential effect levels, with only a small percentage of samples exceeding threshold effect levels, particularly for Ni. Higher concentrations of heavy metals were found in Qinghai and Gansu regions, while Inner Mongolia showed lower levels.

Summary: Limited knowledge of the combined effects of water and sediment properties and metal ionic characteristics on the solid-liquid partitioning of heavy metals constrains the effective management of urban waterways. The study revealed that high salinity can increase the solubility of weakly-bound metals, while dissolved organic matter does not favor metal solubility.

Summary: The study assesses the spatial and seasonal variations of heavy metals in sediment from Fengshan River and uses multiple sediment pollution indices to evaluate the pollution status and potential ecological risk. The results indicate significant spatial variations in heavy metal concentrations, with severe contamination observed in the lower reaches of the river. The study also highlights the importance of organic matters in the distribution of heavy metal pollutants in Fengshan River sediments. The findings offer valuable information for river pollution remediation and urban planning.

Summary: The study reveals that the mineralogical composition of sediments plays a crucial role in the adsorption and desorption of heavy metals. Particulate organic matter is the most influential nutrient in heavy metals adsorption in riverine environments, while particulate phosphorus is more significant in estuarine conditions. Dissolved nutrients do not have a significant positive effect on the release of heavy metals in riverine areas, but dissolved phosphorus increases the transfer of specific metals from sediments to overlying water in estuarine conditions.

Summary: The study investigates the effects of metals mobility derived from mining activities on ultramafic lithology. The results show that the distance has a significant impact on the adsorption and precipitation of metals in the sediment, leading to a decrease in the concentration of potentially toxic metals downstream. This study also highlights the potential risk of asbestos in ultramafic settings.

Summary: The study investigated the occurrence, ecological risk, and sources of heavy metals in the Liaohe River Protected Area from the Bohai Sea watershed. Results showed water, sediment, and soil in the area were contaminated with heavy metals, with Cd, Pb, As, Cr, and Zn being the most prominent pollutants. Sites L25 and L12 were classified as moderately polluted based on the potential ecological risk index values for sediment and soil, respectively.

Summary: The study provides a comprehensive analysis of the water quality of Terme River, indicating overall good water quality with increased ion concentrations in the downstream zone during summer and autumn but below the risk threshold. Children have a higher health risk than adults. Various sources contribute to the changes in water quality, as suggested by the principal component analysis.

Summary: This study found that the influence of land use and configuration on metal partitioning is independent of scale, and population density increases metal bioavailability at the riparian scale. Agricultural lands discharge the highest fractions of dissolved metals at both spatial scales.

Summary: This study investigated the concentrations of heavy metals in the surface sediments of the Mae Chaem River in Thailand. The levels of heavy metals exceeded the standard levels in Thailand, with the primary sources of contamination being residential settlements and agricultural areas. The study also assessed the risk of exposure to heavy-metalbound sediments for children and adults, finding that the risk was low overall but highest for As and Cr in terms of children's exposure.

Summary: The discharge of pollutants into the Yellow River has been controlled since 2013, resulting in an improvement in the overall water quality. However, the contamination status and sources of heavy metals in the river remain unclear. Our study found that heavy metal contents in sediments remained stable over time, but there was a significant reduction in surface water. No heavy metal contamination was observed in surface water, and the distribution of heavy metals along the river did not show significant spatial differences. Sediments were assessed as having a low to moderate contamination degree. The upstream and midstream had higher concentrations of heavy metals compared to the downstream. Anthropogenic activities and soil erosion from the Loess Plateau were identified as important sources of heavy metals in the Yellow River sediments.

Summary: Kumarkhali upazila in Kushtia district of western Bangladesh has been facing severe dye-effluent pollution, with high concentrations of heavy metals exceeding the environmental standards. The study found a lack of awareness among the majority regarding public safety measures and proper disposal procedures, with widespread use of dangerous chemicals during the dyeing process. To protect the local environment and community, stronger enforcement of environmental conservation rules is necessary.
