Summary: This study found that industrial and construction activities are the main sources of metals in road dust, with varying health risks in different seasons. For children, non-exhaust traffic emissions are the main factor contributing to carcinogenic risks in spring and summer. The ingestion route of metals poses the greatest threat to human health.

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.

Summary: This study aimed to analyze organic pollutants and heavy metals in surface sediments from water reservoirs supplying Istanbul, as well as possible sources of contamination. The dominant organic pollutants were PAHs, and polluted sediments were likely sourced from village-town settlements near the dam and highway.

Summary: This study investigated the spatial and seasonal distribution, sources, and associated health risks of polycyclic aromatic hydrocarbons (PAHs) in road dust sampled from ten traffic intersections in a model African city. The study found that concentrations of PAHs in road dust fluctuated and varied significantly between seasons. The study also identified the major sources of PAHs and assessed the cancer risks for children and adults in the city.

Summary: Spatial distributions and concentrations of heavy metals in vegetable plots in Nanjing were analyzed by GIS. The results showed that most heavy metal concentrations exceeded soil environmental quality standards, with positive correlations between heavy metal contents and soil nutrients. Principal components analysis suggested different sources for different heavy metals, indicating potential correlations between Cd and As sources.

Summary: The present study investigated the heavy metal pollution in soils from an area with intensive industrial activities in South China. The results showed that the concentrations of Cd, As, Hg, Cu, Ni, Pb, and Zn were higher than background levels in both surface and subsurface soils. The primary sources of heavy metals were identified as agriculture, industry, transportation, and nature. Anthropogenic activities significantly influenced the spatial distribution of heavy metals in soils. The health risks of heavy metal exposure via different routes were found to be at an unacceptable level, with higher risks for adults compared to children. Therefore, monitoring heavy metal pollution in soils in rapidly developing areas, such as South China, is of great importance.

Summary: Heavy metals in road dusts from a steel-industrial city in Northeastern China pose potential risks to human health and environmental safety. Cd and Zn are more mobile and therefore have higher risks compared to Cr, Cu, Pb, and Ni. The results of this study have important implications for health risk assessment and management in typical steel industrial urban areas.

Summary: The study revealed widespread heavy metal contamination in farmland soil in northwestern Hubei Province, posing a threat to crops like rice. Heavy metals mainly originated from pesticide and fertilizer use as well as atmospheric deposition and transportation exhaust gas. Cd and As were identified as the main noncarcinogenic and carcinogenic factors, respectively, posing the highest health risks to local residents from heavy metals.

Summary: This study analyzed the problem of heavy metals in the surface soil of Zhijin County, a city in Southwest China. The results showed that the heavy metal concentrations were higher than the national average, mainly due to industrial and agricultural activities. The findings of this study are important for environmental management planning, decision-making, and risk assessment.

Summary: This study investigated sediment samples from different regions of the Lake Taihu Basin to analyze the distribution, risks, and sources of heavy metal pollution. The results showed that the concentrations and risks of heavy metals were lower in 2018 compared to 2012. The average concentrations of the seven heavy metals were below the upper chemical exceedance level. The eastern plains and Yangtze Riverside regions had higher contents of heavy metals. The study also identified the main sources of each heavy metal through principal component analysis.

Summary: Salt lakes have a significant impact on the climate, environment, and ecology of semiarid regions. Anthropogenic pollution poses a major threat to the ecological environment of these lakes. A study conducted in the Ordos Plateau examined the salinity, concentration, pollution status, and potential sources of heavy metals in surface sediments from four salt lakes. The results suggest that Cr poses the greatest potential ecological risk, with more severe Ni, Cu, and Zn pollution in Beida Pond and Gouchi Pond. The study also identified pH as a key factor influencing the distribution of heavy metals in the lakes.

Summary: This study investigated heavy metal and cyanide pollution in surface soils and edible plants around Yanzhuang gold tailings ponds in Pinggu District, Beijing. The results showed high concentrations of pollutants around the tailings ponds, with cyanide, As, and Cd identified as the main pollutants. However, the sampled edible plants were found to be basically unpolluted.

Summary: The discharge of pollutants into the Yellow River has been controlled since 2013, resulting in an improvement in the overall water quality. However, the contamination status and sources of heavy metals in the river remain unclear. Our study found that heavy metal contents in sediments remained stable over time, but there was a significant reduction in surface water. No heavy metal contamination was observed in surface water, and the distribution of heavy metals along the river did not show significant spatial differences. Sediments were assessed as having a low to moderate contamination degree. The upstream and midstream had higher concentrations of heavy metals compared to the downstream. Anthropogenic activities and soil erosion from the Loess Plateau were identified as important sources of heavy metals in the Yellow River sediments.

Summary: This study evaluated the concentration and spatial distribution of potentially toxic metals in groundwater in Rafsanjan, Iran, and estimated the carcinogenic and non-carcinogenic risks. The results showed that arsenic and lead concentrations exceeded the maximum limit, while other metals were within the standard level. Children had a higher non-carcinogenic risk of arsenic exposure. It is important to treat and remove arsenic from groundwater resources in the study area.
