“…Similar previous results reported that the total contents of Cd and Cr in soils significantly correlated with those in flowering Chinese cabbage [49]. Soils polluted by industrial activity usually have high proportions of bioavailable contents of TMs [50,51], which lead to the total Cd, Cr, and Cu contents in soils being significantly related to the uptake ability of TMs in vegetables [49,52]. Our previous study also investigated that the average V content in the bioavailable fraction accounted for 25.5% of the total V in the soils surrounding V-containing stone coal smelting sites [53].…”

Dietary exposure to trace metals (TMs) through vegetable consumption has been identified as a potential risk to human health. Fifty-one paired agricultural soil and leaf vegetable samples were collected around V-containing stone coal smelting sites in Hunan Province, China, to study the contamination and transfer characteristics of TMs (Cd, Cr, Cu, Pb, V, and Zn) in the soil–vegetable system. The health risk to local residents through vegetable ingestion was evaluated using Monte Carlo simulations. The results showed that 96.2%, 23.1%, 53.8%, 30.8%, 96.2%, and 69.2% of the soil samples had Cd, Cr, Cu, Pb, V, and Zn contents exceeding their related maximum allowable values, respectively. Cadmium and V were the primary pollutants based on the Igeo values. Moreover, 46.9% and 48.4% of vegetable samples exceeded the maximum permissible levels for Cd and Pb, respectively. There was a negative correlation between the bioaccumulation factors for Cd and V of the vegetable and soil physicochemical properties, including pH, organic matter, and free Fe2O3 content. Ingestion of garland chrysanthemum and pak choi poses high health risks, and Cd, V, and Pb were the primary contributors. These findings will help design strategies to minimize contamination and human exposure to soil–vegetable systems caused by V-containing stone coal smelting.

“…In the past few years, researchers have gradually realized that it is hard to assess the health risks of environmental pollutants exposure accurately by traditional assessment models using single pollution indices such as exposure mass, exposure pathways, and nontargeted health reference dose (RfD). , The chemical speciations of heavy metals and their related bioavailability are also essential factors in the evaluation of their health hazards. , Inorganic As in atmospheric particles are the main species, while trace amounts of MMA have also been found . The toxic effect of arsenic is greatly determined by the chemical forms and possible molecular structure.…”

Inhalation of fine particulate matter PM 2.5 -bound arsenic (PM 2.5 -As) may cause significant cardiovascular damage, due to its high concentration, long transmission range, and good absorption efficiency in organisms. However, both the contribution and the effect of the arsenic exposure pathway, with PM 2.5 as the medium, on cardiovascular system damage in nonferrous smelting sites remain to be studied. In this work, a one-year site sample collection and analysis work showed that the annual concentration of PM 2.5 -As reached 0.74 μg/m 3 , which was 120 times the national standard. The predominant species in the PM 2.5 samples were As (V) and As (III). A panel study among workers revealed that PM 2.5 -As exposure dominantly contributed to human absorption of As. After exposure of mice to PM 2.5 -As for 8 weeks, the accumulation of As in the high exposure group reached equilibrium, and its bioavailability was 24.5%. A series of animal experiments revealed that PM 2.5 -As exposure induced cardiac injury and dysfunction at the environmental relevant concentration and speciation. By integrating environmental and animal exposure assessments, more accurate health risk assessment models exposed to PM 2.5 -As were established for metal smelting areas. Therefore, our research provides an important scientific basis for relevant departments to formulate industry supervision, prevention and control policies.

“…Landfills have been identified as one of the primary sources of groundwater pollution, with groundwater contamination on the rise in recent years (Akhtar et al, 2020;Yang et al, 2022). Areas in close proximity to landfills have a substantial risk of being contaminated by leachate, resulting from the decomposition of organic and inorganic materials within waste piles (Rajoo et al, 2020).…”

The increase in waste volume significantly affects the waste generation at Landfills. Landfills have been identified as one of the main groundwater pollution sources. The aim of this study was to determine the factors influencing cadmium pollution in well water among the community around the Terjun Landfill Medan Marelan District. This study employed an observational analytic design with a cross-sectional approach. It was conducted in the Medan Marelan District adjacent to the Terjun Landfill from August to November 2023. The study population consisted of all households with wells, totaling 218 households. Sample size calculation yielded 64 samples. Sampling technique was conducted using simple random sampling. Sample collection is based on the direction of water flow. Well water samples were examined in the laboratory using spectrophotometry by the Environmental Health and Disease Control Technical Implementation Class I Medan Unit on October 11, 2023, and the results were received on October 30, 2023. Data analysis using SPSS version 21. Data analysis involved three stages: univariate analysis using descriptive statistics and frequency, bivariate analysis using Pearson and ANOVA tests, and multivariate analysis using multiple linear regression at a significance level of 95% (0.05). Statistics results the relationship between well distance and cadmium levels with a value of (P=0.001;r=-0.676), indicating a significant relationship. The relationship between well depth and cadmium levels yielded a value of (P=0.001;r=0.612), indicating a significant relationship. Cadmium levels with soil types obtained a value of (P=0.001), indicating a significant difference. The factor most influencing cadmium pollution in well water around the Terjun Landfill was well distance (ExpB=0.002;P=0.001). The average cadmium levels in well water are still below the drinking water quality standards, however continuous consumption poses risks. The most influential factor is well distance. It is recommended that residents refrain from using well water as a drinking water source. Keywords : Cadmium, landfill, Well Water
