Summary: By collecting heavy metal data from soil and dust samples in 34 cities in China, this study found that the concentrations of Cd, Pb, Cu, and Zn in urban street dust were generally higher than those in urban soil. The main reasons for the high metal concentrations in some cities were the development of metal processing and smelting industries, manufacturing, and the relocation of heavily polluting enterprises. The heavy metal concentrations in urban soil were not correlated with those in urban dust, indicating different long-term and short-term sources of pollution. In most cities, the non-carcinogenic risk of heavy metals in urban soil and dust for children was at a safe level, with lead being the major contributor to total health risk.

Summary: Co-combustion of municipal sewage sludge (MSS) with coal in power plants is a common method for disposal, but it increases the ecological risk due to the high heavy metals content. This study analyzed the properties of fly ash and bottom ash from MSS co-combustion, including ash composition, particle size distribution, heavy metals content, and leaching characteristics. The results showed that the co-combustion had no significant effect on ash composition and heavy metals content order. However, the total content of Cu, Mn, Pb, Zn, and Hg in co-combustion ash was higher than that in coal-fired ash without sludge blending. The leaching concentrations of Cr and Ni exceeded the limit value, indicating a potential ecological risk. The potential ecological risk levels of fly ash and bottom ash were moderate and high, with Cr and Hg as the main contributors.

Summary: The excessive human activity on vegetable farms in Bangladesh due to climate change, food security, and self-sufficiency goals has led to the spread of harmful heavy metal exposure. A study was conducted to assess the toxic metals exposure, characteristics, and human health risk in the soil-vegetable system of two locations in Bangladesh. The results showed higher concentrations of lead (Pb) in vegetable samples compared to the World Health Organization (WHO) allowable limit, and moderate levels of cadmium (Cd) from common sources. However, the human health risks from metal exposure were found to be ineffective in evaluating noncarcinogenic risk patterns and within acceptable range for probable carcinogenic risk patterns. Location B was slightly more vulnerable than location A in terms of metal exposure and pollution distribution.

Summary: Mining activities in opencast coal mines lead to contamination of surrounding soil with heavy metals, and this study aimed to quantify the concentration of heavy metals in soil near the mines. The positive matrix factorization (PMF) model was used to assess pollution sources. The results showed that soil contamination was mainly due to chromium (Cr) in mining areas, and contamination decreased with increasing distance from the mines. The PMF model identified zinc (Zn), nickel (Ni), and manganese (Mn) as major contributors to pollution. This study concluded that soil contamination from coal mining can be mitigated through ecological restoration and phytoremediation.

Summary: Coal mining and coal-fired power plants contribute to atmospheric pollution and health risks due to heavy metal contamination. This study focuses on the pollution characteristics of six heavy metals in atmospheric dust in Xuzhou coal mining area and the potential health risks to residents. The results show that the concentrations of all heavy metals exceeded permissible limits in both winter and summer seasons, with higher levels of Cu, Pb, and Zn in the summer. Inhalation of atmospheric dust dominated by As, Cr, and Pb poses a non-carcinogenic health risk to inhabitants. Furthermore, As and Cr may pose a cancer risk to both children and adults if the current situation continues. Urgent mitigation strategies are needed to address the health risks faced by the residents in this area.
