Summary: Wastewater generation is a significant problem, with untreated wastewater being a major concern. Industries, urban areas, and agriculture are the main contributors to wastewater. Phytoremediation, particularly using the native macrophyte Eichhornia crassipes, shows promise for wastewater treatment. This study evaluates the potential of E. crassipes in different water environments and finds that it exhibits distinct traits depending on the water source. The plants accumulate heavy metals differently and have the potential to be used in phytoremediation due to their ability to thrive in harsh wastewater conditions.

Summary: Analysis of major and trace elements in sediments from the Four River inlets of Dongting Lake revealed differences in element compositions, which are influenced by source lithology, chemical weathering, hydrological sorting, and anthropogenic processes. The findings suggest the need for a geochemical background scheme for future assessment of heavy metal contamination in the watershed sediments.

Summary: The Murray-Darling river basin in Australia is facing severe heavy metal contamination, leading to increased crop productivity, soil fertility loss, and pollution in the surroundings. The study examined heavy metal contamination in eight study sites using various pollution indices, and found a high level of pollution in the basin. The contamination has significant impacts on human health and local environmental conditions.

Summary: Metal emissions from traffic-related facilities are lower compared to other sources, yet they can still contaminate soil. Anthropogenic contaminants like Zn, Pb, and Cu were found to be higher in concentrations in these facilities, with sources mainly attributed to vehicle maintenance and nonexhaust/exhaust emissions. The study used contamination factor (Cf) and multivariate analysis to quantify and evaluate the contamination.

Summary: The study demonstrated that defect engineering can effectively enhance the removal performance of biochar-based composites for U(VI) and Cr(VI). Plasma treatment introducing defects significantly improved the adsorption efficiency, indicating a new pathway for designing high performance absorbents for water remediation.

Summary: Composted sewage sludge (CSS) containing zinc and copper is used as fertilizer in agriculture in Abashiri, Hokkaido, northern Japan. The local environmental risks of these organic fertilizers were studied, specifically focusing on the risks posed by heavy metals to the brackish-water bivalve, Corbicula japonica. The study monitored the long-term effect of CSS application in agricultural fields and evaluated the factors influencing the availability of copper and zinc in the presence of organic fertilizers in pot cultivation. The study also examined the mobility and availability of these heavy metals in organic fertilizers in a field experiment.

Summary: This study focused on investigating the spatial distribution, contamination and origin of heavy metals in the surface sediments of Jangsong tidal flat in Kangryong river estuary, DPR Korea. The findings showed that the heavy metals had diverse sources, with some metals originating from lithogenic sources and others from anthropogenic sources. Despite slight enrichments in some metals, the overall conclusion was that the area was not heavily polluted and had low ecological risk.

Summary: A new heavy metal adsorbent based on humic acid residue modified by sulfuric acid (HAS-SO4) was developed, showing improved adsorption capacity for Hg2+ and Pb2+. The adsorption process followed Langmuir isotherm and pseudo-second-order kinetic models. HAS-SO4 effectively passivated Hg2+ and Pb2+ in contaminated soil, reducing their leaching risk and changing their morphology.

Summary: Due to ongoing human activities, heavy metals are accumulating in the soil, resulting in the quick spread of heavy metal pollution and a disastrous effect on agricultural products. However, the experiment showed that lead-tolerant-plant-growth-promoting rhizobacteria (LTPGPR) significantly improved plant growth, yield, antioxidant activities, and lead uptake in Indian mustard, as well as reducing lead contents.

Summary: Soil contamination by heavy metals and metalloids is a significant environmental challenge. This study tested a novel remediation technology using a ternary amending agent to immobilize arsenic and lead in contaminated soil. The results show that the amending agent effectively reduced the leachable concentrations of arsenic and lead in the soil.
