Summary: This study assessed the concentrations of heavy metals in soils at the Kpone landfill site in Ghana using AAS, and found extreme pollution levels throughout the site. The main sources of heavy metals were identified as waste materials and traffic activities, with significant ecological and health risks posed to the surrounding area.

Summary: The study found that the heavy metal pollution in farmland soils in Beijing is relatively low, posing minimal risk to the surrounding environment and human health. The IICQ method is suitable for evaluating soil heavy metal composition and individual impact, providing a more accurate overall ecological assessment of the soil-crop-human health system.

Summary: This study analyzes the interaction between soil quality and heavy metal pollution. The results show that with increasing soil quality, heavy metal contamination and ecological and health risks increase significantly. Industrial activities, agricultural activities, and coal combustion are the major pollution sources. Policies should be formulated to control industrial pollution and improve the ecological environment.

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 assessed the oral bioaccessibility and human health risk of metal(loid)s in potentially polluted urban topsoils, finding relatively low levels of pollution. However, soil pica behavior may lead to non-carcinogenic and carcinogenic risks, especially for children with lapses of adult supervision.

Summary: The study assessed urban soil pollution by trace elements in China and found that 11% of cities are heavily polluted. Some cities exceed the standardly accepted tolerable levels of risk, with urban green spaces being threatened. It is recommended to alter the policy of urbanization and develop green infrastructures adapted to high contamination levels.

Summary: Potentially toxic metals in agricultural soil in China have raised environmental concerns, with a study finding their occurrence and distribution across 18 provinces. The health and ecological risks associated with these metals were evaluated, and their sources were predicted. Overall, the concentrations of the metals were below the threshold values for agricultural lands. However, there was a considerable cumulative ecological risk in certain regions, and the sources were mainly attributed to geological or anthropogenic activities.

Summary: The study conducted on heavy metal pollution in soil samples from Jinan Iron & Steel Group revealed significant contamination of zinc, lead, cadmium, and mercury. The distribution patterns of heavy metals in the soil exhibited both horizontal and vertical accumulation characteristics. Fractionation analysis results and assessment of soil pollution level indicate varying degrees of pollution by lead, cadmium, and mercury in the studied area.

Summary: This study evaluated the bioaccumulation of chromium and nickel in rice grown in serpentine-derived paddy soils in the Philippines. Results showed that both metals were mainly accumulated in the roots of rice plants, with low health risks for male and female Filipino adults. Further studies are needed to understand the dynamics of heavy metal bioavailability in other crops and to ensure consumer safety in serpentine areas.

Summary: This study summarizes the pollution status, spatiotemporal patterns, and drivers of heavy metal accumulation in agricultural soils, rice, and wheat in China. Cadmium (Cd) was found to be the most prevalent contaminant in soils, with an increasing trend in pollution cases. Mining activities were identified as the main anthropogenic sources of agricultural soil heavy metals. The exceedance rate of Cd and lead (Pb) in rice and wheat was relatively high, and the concentration of heavy metals in crops increased gradually from north to south.

Summary: The study reveals higher levels of heavy metals in the soil near Ranwu Lake compared to the sediment. The main sources of these heavy metals are both anthropogenic activities, such as vehicle emissions and mining, as well as natural factors. Evaluating and analyzing the sources and risks of these heavy metals is crucial for protecting the water and soil resources of the lake.

Summary: Soil pollution with heavy metals is a global problem. This research investigates the extraction of heavy metals from polluted soils using different extraction agents. The results show low extraction efficiency for all proposed extraction solutions, but higher removal efficiencies can be achieved under specific conditions. Further research is needed to find better solutions for pollutant removal.

Summary: The concentrations of eight heavy metals, except for Pb and Cr, were above background levels in Guizhou soils. As, Cu, Zn, Pb, Cr, Cd, and Ni reached pollution levels, while Hg fell into the category of moderate contamination. Cd and Hg posed considerable or very high potential ecological risks.

Summary: This study focused on riparian soils in the lower sections of the Lhasa River to examine the characteristics and sources of heavy metals in high-cold regions. The research found that the topsoil was more polluted than the deep soil, with Cd being the primary contributor to overall contamination. The study identified five sources for the six heavy metals and concluded that the heavy metals in the riparian soil pose no harm to human health. Monitoring of these heavy metals is important to ensure their safe utilization.
