Summary: The study found that the southern Shanghai port was heavily polluted by heavy metals, primarily Cd, Pb, Cr, and Cu; while Yangshan Port water was highly polluted, with other areas having lower pollution levels. Cd, Hg, and Zn pollution in sediments was severe, with most sampling sites posing moderate ecological risks.

Summary: The study conducted in Daya Bay's northwestern region collected seasonal surface sediment samples to assess pollution and ecological risks, finding that heavy metal concentrations were generally below standard criteria, but higher in some sites during spring, particularly for Cr and As. The ecological risk indices indicated moderate to considerable risks, with few sites showing high ecological risk. Anthropogenic activities affected Cu, Hg, and Pb levels, while As appeared to be sourced from natural inputs like the atmosphere. Overall, human impacts played a significant role in heavy metal contamination in the environment.

Summary: The study used positive matrix factorization (PMF) and a GeoDetector model to assess the sources and ecological risks of heavy metal contamination in the Yancheng Coastal Wetland. Wetland environments were found to have a strong ability to sequester heavy metals, with parent soil material, agriculture, and industrial pollutants identified as the main sources. The ecological harm of heavy metal exposure was minimal, except for Cd and Hg, which were primarily caused by vehicle emissions.

Summary: China has a large number of fishing ports along its coastal areas, but there have been few studies on the pollution and ecological risks of heavy metals in these ports. This study detected heavy metals in sediment samples collected from 37 fishing ports along the Yellow Sea and Bohai Sea coasts. The results showed that copper and cadmium were the major pollutants, and most ports had moderate ecological risks.

Summary: Global mangrove wetlands are increasingly impacted by human activities along the coast. This study focuses on the Zhanjiang mangrove wetland, the largest wetland adjacent to a highly developed bay area in China. Surface sediments were collected from different plant communities and analyzed for potentially harmful trace elements (PHTEs). The results show that most PHTEs were slightly enriched, with significant pollution of cadmium (Cd) and moderate potential ecological risk. The risk of the mangrove wetland is higher compared to grassland and farmland. The source of PHTEs is mainly attributed to local anthropogenic activities for mercury (Hg), nickel (Ni), copper (Cu), zinc (Zn), arsenic (As), and lead (Pb), natural geological processes for chromium (Cr), and atmospheric deposition of regional industrial pollution for Cd. The findings highlight the need for stricter implementation of wetland protection laws to achieve ecological civilization. This study provides valuable insights for wetland conservation and management in coastal cities.

Summary: Heavy metals elements not only affect ecosystems but also human health. The study found that only Cd and Pb exceeded their background values in the topsoil of the Zoige alpine basin, with Cd being 2.02- and 1.55-fold higher than its background value in May and September, respectively, and Pb being 2.35- and 2.17-fold higher than its background value in May and September, respectively. The comprehensive potential ecological risk index indicated low pollution levels in the study area. Spatial interpolation suggested that Cd and Pb pollution might be related to tourism and transportation, but the low biological absorption coefficient of heavy metals in forage indicated minimal impact on yak breeding. Overall, the soil in the basin was lightly contaminated with Cd and Pb due to rapid development in animal husbandry and tourism. Spatial variation of heavy metals was primarily influenced by structural factors, while random factors such as overgrazing influenced the content and distribution of soil heavy metals.

Summary: The Shahe Reservoir in the Northern Canal Basin was studied to analyze the spatial distribution of heavy metals in sediments. The results showed that there was a low level of heavy metal pollution and ecological risk in the reservoir, possibly originating from external wastewater input.

Summary: The study analyzed 128 stream sediment samples collected in the Misiones province of Argentina, focusing on the concentration, spatial distribution, local pollution level, and potential ecological risk of eight heavy metals. The results showed that most elements had concentrations higher than the abundance of continental crust, with Cu and Zn showing consistent spatial distribution patterns and other elements varying. Factor analysis suggested that some elements were mainly influenced by geological background, while others were linked to human activities. Ecological risk assessment found that Cu was heavily polluted, while Pb and Zn were mildly polluted, and As and Cu posed the highest ecological risks.

Summary: The study revealed that while the overall soil quality in the upstream watershed of the Guanting and Miyun Reservoirs in Beijing is excellent, there are relatively high contamination risks for Cd, Cu, Zn, and Cr. Through the analysis of heavy metal concentrations, factor analysis, and cluster analysis, the sources of different heavy metals were identified.

Summary: The study investigated the pollution level, spatial distribution characteristics, and origins of trace metals in the topsoil of the upstream area of the Guanzhong Basin. The most contaminated elements were Cr, Cu, Cd, and Pb, and the average levels of all trace metal elements exceeded their local background values. The primary sources of contamination were agriculture, industry, mining, metal smelting, and traffic emissions. This study provides reliable references for determining the sources of trace metals in the region.

Summary: Mangroves have a high ecological service value and play an important role in carbon neutrality. However, the quality of mangrove wetland soil is being affected by heavy metal pollution, resulting in a decline in ecological services. Research in Hainan, China, found that heavy metals mainly originate from ships, aquaculture, agriculture, weathering of parent rocks, and atmospheric deposition. The results also showed that the surface layer of sediments in terrestrial areas is more susceptible to heavy metal contamination.

Summary: The epicontinental seas to the east of China, particularly the Bohai Strait, have been heavily impacted by heavy metal pollution. The investigation of the surface sediments in the northern Bohai Strait revealed high concentrations of heavy metal elements, especially As, Cd, and Pb, posing a significant ecological risk. The study also found that the accumulation of Hg, Cr, and Zn was associated with the deposition of organic matter, and the pollutants mainly originated from the eastern parts of the North Yellow Sea.
