Summary: The study found that the concentrations of heavy metals in Dome A in Antarctica were influenced by human activities, mainly from Australia and South America. By analyzing the relationship between trace element fluxes and sea ice concentration, sea surface temperature, and air temperature, it was revealed that the deposition and transport of atmospheric aerosols at Dome A were influenced by circum-Antarctic atmospheric circulations.

Summary: The study reveals that Baltic Sea sediments record significant loads of Cd, Zn, and Pb, influenced by redox conditions. Concentrations of these metals increased from the early 19th century to the 1970s, then decreased, but are still above pre-industrial levels. Pre-industrial Cd, Zn, and Pb concentrations were higher than those suggested by the Swedish EPA. The reduction in pollution of these metals since the 1980s highlights the importance of environmental governance.

Summary: In this study, three methods for moss biomonitoring were compared, revealing that while they yield relatively similar results, the interpretations are not equivalent and none of the methods provides a reliable estimate of soil contribution to moss element concentrations. Therefore, it is recommended to use moss for atmospheric biomonitoring only for elements like Cu, Zn, and Cd, for which soil contribution is low.

Summary: Renewal of aging water infrastructure in urban areas offers opportunities for implementing green infrastructure (GI) systems. However, historical soil contamination and connections to road systems can mobilize legacy pollutants, such as lead, into GI installations. Soil metal chemistry and accumulation patterns were investigated in six Pittsburgh GI installations, with trace metals accumulating at roadside edges and potential remobilization of historically contaminated soils. These findings highlight the importance of understanding metal transport and sequestration in GI systems for effective stormwater planning and management.

Summary: The historical atmospheric heavy metal pollution in southern China over the past 200 years was studied using analysis of a sediment core from Huguangyan Maar Lake. The study found that Zn, Cd, Sb, Tl, and Pb in the lake were closely related to human activities, while Cr and Ni were mainly from the weathering of surrounding basalt. The increase of atmospheric Pb in southern China occurred earlier than in other regions of China, mainly due to war and the use of leaded gasoline. After 2000, atmospheric Pb continued to rise due to continued industrial development.

Summary: The assessment of heavy metal soil pollution in Kosovo is incomplete. The research aims to evaluate the level and spatial distribution of heavy metals and biogenic elements in soil samples throughout the country. The concentrations of lead, cadmium, copper, and nickel exceeded the maximum thresholds set by the EU directive in some sampling locations.

Summary: This study reveals the current status of heavy metal contamination in the Blesbokspruit wetland and the role of localised macrophytes in their phytoremediation. While the concentration of heavy metals in water samples meets the standards throughout the wetland, sediment samples show significantly higher levels that exceed international guidelines. The findings suggest that different macrophytes have varying bioaccumulation potentials, with E. crassipes being the most effective in accumulating heavy metals. Therefore, utilizing hyperaccumulating macrophytes for natural recovery can alleviate the anthropogenic stress on this valuable ecosystem.

Summary: Using a trait-based approach, this study assessed the response of macrobenthic communities in three intertidal zones in Laoshan Bay, China, to anthropogenic pressures represented by land-based aquaculture pond area and heavy metals. The results showed significant differences in functional traits composition among the regions, with heavily polluted areas exhibiting different traits compared to less polluted areas. Sediment-related pollution factors and pond area were identified as major contributors to variance in functional traits of macrobenthic communities, indicating direct and/or indirect effects of human activities on these ecosystems.

Summary: The Mar Menor lagoon is an important economic engine due to its high biological production and environmental quality. However, human activities have put its ecological integrity at risk. Mining activity since Roman times has contributed heavy metals to the lagoon sediments, and current heavy metal concentration and distribution are influenced by hydrographic and biogeochemical processes.

Summary: This study provides an updated analysis of urban pollution in the Saida city watershed, focusing on the presence of heavy metals and organic pollution in urban drainage sediments. The results show that rainfall events and sediment sampling periods have an influence on pollution generation and regeneration processes. Pollution indices and factors are used to assess the degree of pollution in the study area, and the results indicate significant pollution of the investigated sediments. Furthermore, the sediments possess a high to severe potential ecological risk rating.

Summary: This study aimed to evaluate the concentrations and distribution of PTEs in soils from an industrialized region, as well as identify their possible sources. Analysis of 442 soil samples revealed high variability in PTEs in both organic and mineral soils. Despite low pollution levels in the area, periodic assessment of soil may be necessary to prevent future accumulation. This information could be valuable for policy-makers in promoting sustainable agriculture and forestry for ecosystem health and overall welfare.

Summary: Urbanization leads to significant changes in terrestrial ecosystems, resulting in soil degradation and pollution. The study in Eastern India found high levels of microplastics in urban soils, along with heavy metal contamination, indicating the severity of soil pollution in small urban settlements due to unmanaged human activities.
