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: 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 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: This study investigated the concentration of nine heavy metals in Oreochromis niloticus and Ipomoea aquatica in Agodi reservoir, Nigeria. The results showed that the metals accumulated more in O. niloticus than in I. aquatica. Most of the examined metals exceeded the safety limit, and O. niloticus had lower tolerance for heavy metals. Additionally, metal concentration and ecological risk quotient were higher in the wet season for O. niloticus.

Summary: Heavy metal pollution, especially the Pb concentration in sediment, has a significant impact on aquatic ecosystems. The variations in heavy metal concentrations in sediments are linked to changes in sediment and tadpoles' gut microbiomes. Pb leads to a trade-off between the proportions of Burkholderiales and Verrucomicrobiae in sediment microbiota and affects methane, sulfide, and nitrate metabolisms. Tadpoles with high sediment Pb content have a low abundance of gut aerobic bacteria and a large relative gut weight.

Summary: This study analyzed sediment cores from two subalpine lakes in Shanxi Province, North China to reveal the variations of atmospheric mercury over the past two centuries. It found that atmospheric mercury was mainly influenced by regional deposition and showed a rapid increase since the 1950s, which was related to the industrial development in and around Shanxi Province. This study suggests the dominant contribution of domestic mercury emissions in the region.

Summary: It is essential to assess the contamination of heavy metal (HM) in lakes in dissolved matter, suspended particular matter (SPM), and sediments. This study evaluated the risks of HMs in Caohai, China, in water, SPM, and sediment, and analyzed the changes in sediment HM contamination with historical data. The transport of HM was mainly influenced by SPM load, and the concentrations of Zn, Pb, and Cd in SPM and sediment were significantly higher than the upper continental crust (UCC) values. SPM and sediments were polluted and had high toxicity risks, originating from industrial and agricultural sources. The concentrations of Zn, Pb, and Cd in Caohai sediments showed an increase compared to previous years. This research provides valuable reference data for the remediation of polluted karst lakes.

Summary: This study applied a multi-isotope and multi-elemental characterization to different antifouling paints (APs) for the first time, to improve their tracking in marine environments. The high contents of copper and zinc were observed in APs. The elemental fingerprint analysis revealed that APs, tires, and brake pads have distinct fingerprints. However, the first attempt to apply this method in highly urbanized harbor areas showed difficulties in source apportionments.

Summary: Zeolites are extensively studied materials for adsorption and ion exchange with wide applications in agriculture and environmental protection. Natural zeolites are widely researched as soil conditioners and fertilizer additives in agriculture, while synthesized zeolites are gaining attention in environmental remediation. Despite numerous studies on zeolites' applications in environmental protection, their full potential is yet to be fully explored.

Summary: Environmental exposures such as heavy metals, noise pollution, light pollution, second-hand smoke, and air pollution have been shown to have detrimental effects on various aspects of sleep health. While there is growing empirical evidence supporting the association between these exposures and sleep problems, the relationship between light exposure and sleep remains unclear and requires further investigation to elucidate the exact mechanisms of action.

Summary: The study found that phosphorus in sediments along the Jiangsu Coast primarily originates from the Yellow River, with the distribution pattern of phosphorus species dependent on both phosphorus sources and local environments. Biologically available phosphorus species mainly include exchangeable and organic phosphorus fractions, which are overall influenced by sediment grain sizes and organic matter content.

Summary: Cyanide is a hazardous ion, and there is a high demand for sensitive and selective sensors for its monitoring. The novel chemosensor TBC-DPPN can detect CN- in water samples through visual and vibrational spectroscopy, with high selectivity and sensitivity. The mechanism of CN- sensing by TBC-DPPN sensor is confirmed by spectral measurements and DFT calculations, enabling detection of CN- in water below recommended limits.

Summary: The study showed that unassembled LDHs exhibited greater adsorption capacities and shorter equilibrium time for methyl orange, possibly due to their loose structure and more exposed adsorption sites. This suggests that unassembled LDHs could be an effective pathway for exploring the adsorption sites of LDHs.

Summary: This study examines the combined effects of catchment characteristics, sediment properties, and emerging pollutants (microplastics) on the presence of metals in urban river sediments. The results show variations in metal concentrations and enrichment along the Brisbane River, with crustal metals correlated with sediment properties and anthropogenic source metals correlated with catchment characteristics. Additionally, the presence of metals in sediments is positively correlated with microplastics concentration and negatively correlated with microplastics hazard indices.

Summary: The integration of heavy metal leaching based on the PROFILE weathering model into the steady-state critical load (SSCL) of heavy metals was conducted to assess the environmental capacity of agro-ecosystem. The leaching rates of Hg, As, Cd, Cr, Pb, Cu, and Zn in paddy soil were quantified, and their correlations with pH, CaO, TFe2O3, and Corg were analyzed. Atmospheric deposition, rice plant uptake, and leaching were identified as the main input and output pathways for heavy metals in agricultural soil. The SSCL model provides new insights for the establishment of environment management in agricultural soils.

Summary: This study investigated the transfer and accumulation characteristics of rare earth elements (REEs) in the Mengku tea region. It was found that light REEs were easily enriched in rock, soil, and tea. The anomalies of Ce and Eu in rocks and soil were negative, while Ce levels in soil showed slightly positive anomalies. The transfer of REEs was mainly affected by K, Na, Ca, and Mg, with LREEs being mainly enriched in tea through Na+ channels.

Summary: This paper investigates glacial sediments in the Ny-Ålesund region of the Arctic and clarifies the response of polar environment to global changes through geochemical characteristics of glacial sediments. The results show that the main factors affecting the elements distribution in the sediments are soil formation, bedrock and weathering, and biological activity. The formation of stone circles leads to lower chemical weathering in the sediments. Changes in carbonate content with glacier front retreating indicate the importance of biological weathering.
