“…Factor 3 was allocated by Cr, Cu, Ni, and As, which contributed 71.7%, 52.7%, 64.0%, and 62.9%, respectively. Generally, Cr and Ni mainly originate from soil parent materials and natural processes, and are largely unaffected by human activities in the environment (Liang et al, 2023). In this study, the ratios of Cr and Ni in the soil samples exceeding the background values were the lowest among all sampling points.…”

“…This suggested that anthropogenic sources had a significant impact on the levels of Hg found in the areas. Previous studies have shown that industrial activities such as fossil fuel combustion, metal smelting, and cement production are important sources of Hg accumulation in soil (Liang et al, 2023). Fossil fuel combustion alone can account for 45% of anthropogenic Hg emissions (Streets et al, 2011).…”

“…The rapidly advancing process of urbanization has emerged as a formidable catalyst for economic expansion and societal progress. Urban agglomerations have played an indispensable role in propelling the nation's overall economic development (Rai et al, 2019;Wang et al, 2021;Liang et al, 2023). Taking the Guangdong-Hong Kong-Macao Greater Bay Area (GBA) as an example, the GBA's total economic output reached $1.37 trillion U.S. dollars in its inaugural year, approaching that of the Greater New York City Area (Zhou et al, 2022).…”

“…Soil pollution is considered one of the most severe environmental concerns due to its concealed, hysteretic, cumulative, and irreversible nature (Liang et al, 2023). The urban soil is continuously subjected to the accumulation of metal(loids) from either localized or diffuse sources, including industry discharge through atmospheric deposition or wastewater irrigation, residential sanitary waste, traffic emissions, livestock manure and pesticide etc (Yang et al, 2020;.…”

The heavy metal(loid)s enriched in soil can pose a threat to soil environmental quality and human health. Given the rapid development of the Guangdong-Hongkong-Macao Great Bay Area (GBA), soil pollution cannot be overlooked. To effectively tackle this problem and ensure precise prevention and control measures, accurate identification of pollution sources becomes indispensable.The present study involved the collection of 118 surface soil samples in Jiangmen city, with a focus on investigating the concentration, spatial distribution characteristics, sources, and health risks of heavy metal(loid)s in the soil. The findings revealed that the average concentrations of As, Cd, Cu, Pb, and Hg exceeded the background values, with particularly elevated levels observed for environmental As concentration. Elevated concentrations of heavy metal(loid)s were prdominantly concentrated in urban areas such as Pengjiang and Jianghai District. The qualitative and quantitative allocation of soil pollution sources identified through the coupling pearson correlation and PMF model, reveal that vehicle and shipping emissions, industrial emission and, parent material and agriculral activities are the primary contributors to soil pollution. Additionally, it is observed that shipping emissions significantly impact the source of soil Pb in Jiangmen. Futhermore, based on ecological risk assessment, the regions of Jianghai and Pengjiang exhibit the highest potential ecological risk with an RI value of 300. Health risks associated with different sources indicate that industrial emissions have the most significant impact on both carcinogenic and non-carcinogenic risks for children and adults in Jiangmen. This study provides a fundamental reference for heavy metal(loid)s contamination in the soil of Jiangmen City. Considering the future development of the GBA, local management authorities should enhance their focus on long-term pollution resulting from industrial production in Jiangmen and implement targeted control measures based on pollution sources.

“…Table 1 shows the concentration of heavy metals in the soil at different depths. It can be observed that the concentration of heavy metals in the soil at all layers exceeds the control point, indicating that human actions have interfered with the dispersion of heavy metals at these places (Liang et al, 2023). In the mining area, the heavy metal content at Point 6 is much higher than that at Point 1, which may be related to mining activities (such as blasting and mineral transportation).…”

The study of heavy metal interactions with soils under specific climatic circumstances might lead to a better understanding of heavy metal migration and provide further information for local pollution control. In this work, we collected soil samples from the world's largest light rare earth mining district, Bayan Obo mine district, and assessed the heavy metal content in the soil at various depths. The extraction effectiveness of Diethylenetriaminepentaacetic acid (DTPA) and Toxicity Characteristic Leaching Procedure (TCLP) for heavy metals in surface soil were compared. Furthermore, we studied the longitudinal transport of heavy metals under precipitation conditions using simulated experiments and kinetic fitting. We discovered that pH has a significant impact on heavy metal release. Precipitation easily transports Zn, Pb, and Cr to deeper layers of the soil. The modified Elvoich equation could better describe heavy metal release patterns.

The Hanjiang Reservoir is an important water source for the middle route of China's South-to-North Water Diversion Project. The problems of water and soil quality in the Hanjiang reservoir have enormous biological and environmental impacts, resistant genetic contamination has emerged, but only few studies are concerned the correlation between heavy metals and metal resistance genes (MRGs). In this study, 8 antibiotics and 19 heavy metals were analyzed, the results showed that the highest antibiotic content was tetracycline, with mean concentrations of 43.2 µg/kg and 0.0221 µg/L. Mn was the highest heavy metal in soil with a content of 1,408.28 µg/kg, and in water was Zn with a content of 10.61 µg/L. We found that the most abundant antibiotic resistance genes (ARGs) and MRGs in the study area were bacA and arsT genes, coding for resistance mechanisms to bacitracin and arsenic, respectively. The data showed that heavy metals had a greater impact on antibiotic genes than antibiotics, and antagonism between resistance genes was more signi cant. This work expands our understanding of the correlations of antibiotics, heavy metals, and resistance genes in the Hanjiang reservoir, indicating that more attention should be paid to the effects of resistance genes and the quality of water.
