“…When comparing the heavy metals in the water of the subsidence pond with the other coal mining areas, all of the heavy metals concentrations in the water of the subsidence ponds in this study were higher than those values in the subsidence pond from Huaibei [9]. Low levels of Pb, Ni, and Mn were observed in this research, compared with those values in the water of ponds from Jining City [2], Karanpura coal mine [23], and Okpara coal mine [18].…”

“…Actually, the subsidence ponds are near the coal mine, coal power plant, and coal gangue pile. Cr, Ni, Cu, As, and Mn could be released during coal processing, acid mining drainage, and coal combustion [9]. Furthermore, some metals could also be released by the immersed coal gangue at the bottom of the subsidence pond [29].…”

“…Chen et al [3] observed that the non-carcinogenic health risk values of Cu, Ni, Pb, Cd, Cr, V, Fe, Mn, and Zn in surface water from six different subsidence water bodies were less than 1, and the total carcinogenic risk values for Cr, Ni, and As in every subsidence water via two exposure pathways were greater than the maximum acceptable level in the Huainan coal mining area. Tan et al (2020) [9] found that the As concentration in the subsidence pond water slightly exceeded Class III of China's Environmental Quality Standards for Surface Water. Therefore, if the subsidence pond was proposed for resource utilization in the Huainan coalfield, the heavy metals levels in the pond water should be monitored, and the metal risk also needs to be assessed, to assure water safety to the people.…”

The subsidence pond is an important water resource for coal mining areas in China. In order to take full advantage of the subsidence pond, a floating photovoltaic cover or a pillaring photovoltaic cover were installed on the surface water of the subsidence pond in the Huainan coal field. Different photovoltaic systems (floating/pilling cover) equipped in the subsidence pond may affect the water quality; thus, assessing the metals in the subsidence pond with the solar photovoltaic system is of great importance for environment control. In this research, surface water samples were collected from three different subsidence ponds, with or without the solar photovoltaic system. The concentrations of Pb, Cr, Ni, Cu, As, Mn, and Zn in the water of the subsidence pond were determined using ICP-MS and AFS. Then, the health risk posed by the heavy metal in different subsidence pond waters via the ingestion pathway was evaluated and analyzed using the assessment model recommended by USEPA. The results indicated that the mean concentrations of Pb, Cr, Ni, Cu, As, Mn, and Zn in the water of different subsidence ponds were less than the environmental quality standards for surface water (China, Grade II). Cr showed a higher non-carcinogenic risk than the other metals, and the photovoltaic cover actually decreased the total non-carcinogenic risk in the photovoltaic subsidence pond compared with the natural subsidence pond. Non-carcinogenic risks of single and total heavy metals in the subsidence ponds with or without solar photovoltaic systems were below 1; thus, these risks in different subsidence ponds were considered to be at an acceptable level. However, the potential single carcinogenic risks of Cr, Ni, and As; and the multielement carcinogenic risks of Pb, Cr, Ni, and As exceeded the limits of 1 × 10−6 and 1 × 10−4, respectively, suggesting that these metals showed single and total potential health risks in the subsidence pond, with or without the solar photovoltaic system. Further, the subsidence pond with the photovoltaic cover showed higher total carcinogenic risks in comparison with the natural subsidence pond. Therefore, a subsidence pond with a solar photovoltaic system should be monitored periodically to ensure the water safety.

“…These two pathways and two groups of people (adults and children) were considered in this study. In this study, the assessment factors in evaluating the environmental risk of shallow groundwater included Ni, Cd, Pb, and Cr as carcinogens health risk assessment models [17,30]; However, chemical carcinogens also exert non-carcinogenic effects [17,30]. Therefore, Mn, Ni, Cu, Zn, Sr, Cd, Pb, and Cr were also used as non-carcinogen health risk assessment models.…”

This study aimed to assess the heavy metal (Mn, Ni, Cu, Zn, Sr, Cd, Pb, and Cr) pollution characteristics, sources, and human health risks in shallow groundwater in the impact zones of urban and rural semi-intensive poultry farms in Suzhou City. Ordinary kriging interpolation showed that poultry farming contributed substantially to the pollution of shallow groundwater by Mn, Zn, and Cu. Positive matrix factorization was applied to identify the sources of heavy metals, and the health risks were assessed based on the hazard index and carcinogenic risks of the various sources. Heavy metal enrichment was closely related to anthropogenic activities. In addition, four sources were identified: poultry manure (29.33%), natural source (27.94%), industrial activities (22.29%), and poultry wastewater (20.48%). The main exposure route of carcinogenic and non-carcinogenic risks to adults and children was oral ingestion. The non-carcinogenic risk of oral ingestion in children was higher than that in adults; the carcinogenic risk was higher in adults than in children. Poultry manure (42.0%) was considered the largest contributor to non-carcinogenic risk, followed by poultry wastewater (21%), industrial activities (20%), and natural sources (17%). Industrial activity (44%) was the primary contributor to carcinogenic risk, followed by poultry wastewater (25%), poultry manure (19%), and natural sources (12%).

“…Therefore, the environmental quality of the water and the sediments of coal mining collapsed lakes haves received extensive attention. Investigations show that the research on coal mining subsidence lakes mostly focuses on water quality evaluation, water body and ecological restoration methods, and benthic community structure 3 . However, so far, there are relatively few studies on the bacterial community composition and diversity in the sediments of the Huaibei coal mining subsidence lake area.…”

The collapse lake area due to coal mining in Huaibei shows high biodiversity, but the bacterial community composition and diversity in the lake sediments are still rarely studied. Therefore, based on 16S rRNA high-throughput sequencing and combined with analysis of environmental factors, we comparatively analyzed the bacterial community composition and diversity of surface sediments from East Lake (DH) and South Lake (NH) and Middle Lake (ZH) in the collapse lake area of Huaibei. The bacterial community compositions are significantly different in the sediments among Huaibei collapsed lakes, with DH having the largest number of species, and NH having a higher species diversity. Pseudomonadota is the most abundant phylum in the sediments of DH and NH, while the most abundant phyla in ZH are Bacteroidales, Chloroflexales, Acidobacteriales, and Firmicutes. Anaerolineae (24.05% ± 0.20%) is the most abundant class in the DH sediments, and Gammaproteobacteria (25.94% ± 0.40%) dominates the NH sediments, Bacteroidia (32.12% ± 1.32%) and Clostridia (21.98% ± 0.90%) contribute more than 50% to the bacteria in the sediments of ZH. Redundancy analysis (RDA) shows that pH, TN, and TP are the main environmental factors affecting the bacterial community composition in the sediments of the collapsed lake area. The results reveal the bacterial community composition and biodiversity in the sediments of the Huaibei coal mining collapsed lakes, and provide new insights for the subsequent ecological conservation and restoration of the coal mining collapsed lakes.
