“…It is then important to monitor the presence and concentration of these toxic heavy metals in the environment, especially in areas where introduction may occur, like in open landfill sites. The findings of this study on metal analysis of the soil sample from the landfill site coincide with the findings of Beinabaj et al (2023) in which Fe had the highest concentration (22.94 mg/kg) among the metals they have detected in the landfill leachates from the new landfills in Tehran. They have also noted the high concentration of Mn (33.65-34.14 mg/kg) they have detected in the landfill soil.…”

“…They have also noted the high concentration of Mn (33.65-34.14 mg/kg) they have detected in the landfill soil. Like the present study, Beinabaj et al (2023) also detected Cd at low concentration. In the present study, the high concentrations of Fe and Mn compared to the other metals analyzed in the soil sample collected can be attributed to sources such as cast iron from old tools, equipment, and alike for Fe while blade, bottle caps, galvanizing goods, insecticides, pigments and paints for Mn that are dumped in the landfill site (Kanmani and Gandhimathi, 2013;Beinabaj et al, 2023).…”

“…Problems with the possible release of these toxic chemicals, including heavy metals associated with landfill sites may result to groundwater pollution, plant phytotoxicity and a decline in crop and soil production near the dumpsite. Also, the absorption of heavy metals by plants marks the entry of heavy metals to food chain and their successive accumulation along food chain has a critical threat to the health of animals and humans (Nyiramigisha et al, 2021;Ayilara and Babalola, 2023;Beinabaj et al, 2023). The toxicity of heavy metals to living systems is well-recognized.…”

Excessive deposition of heavy metals into the environment due to anthropogenic activities necessitates an eco-friendly clean-up strategy. Among microorganisms, limited studies have been made on the mycoremediation potential of microfungi. This paper evaluated three landfill microfungal isolates of Aspergillus species for tolerance and uptake to Cd and Mn. Culture media optimization was also performed for the evaluation of the tolerance index and heavy metal analysis of soil samples from the landfill site. Among the nine heavy metals analyzed, Mn and Fe were detected in relatively high amounts, while Cd, Ni, and Cu were detected in a moderate range. Luxuriant mycelial growth of A. oryzae (MK120548.1) and A. flavus (MH864264.1) was observed in potato dextrose agar while A. terreus (MH047280.1) grew best in potato sucrose agar. In terms of tolerance index, A. oryzae (MK120548.1) and A. flavus (MH864264.1) demonstrated high tolerance to Cd up to 10 mg/kg. A. oryzae (MK120548.1) showed high tolerance to Mn up to 1,000 mg/kg while A. flavus (MH864264.1) exhibited a very high 10,000 mg/kg tolerance. In terms of metal uptake, A. oryzae (MK120548.1) showed the highest metal uptake of up to 654 mg/kg of Cd, while A. terreus (MH047280.1) exhibited the highest metal uptake of 997 mg/kg ofMn. With these findings, A. oryzae (MK120548.1), A. flavus (MH864264.1), and A. terreus (MH047280.1) have considerable mycoremediation potential. Bioremediation studies in conjunction with plants can be explored to further assess the potential of these Aspergillus species.

“…Contamination of well water in the vicinity of the landfill is caused by the leaching of waste piles, carrying dissolved substances or by-products of the waste decomposition process, resulting in leachate (Ergene et al, 2022). The leachate enters the water following the groundwater flow direction, eventually converging into wells (Beinabaj et al, 2023). Leachate contains various heavy metals, including cadmium (Astuti 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

“…In general, factors like rainfall, the amount of heavy metal deposition in the soil, the concentration of heavy metals in the leachate, and the length of time that heavy metals are absorbed determine how different the concentration of heavy metals is in land ll soil (44).…”

Population concentration in metropolitan areas generates and disposes of substantial quantities of waste with varying compositions. Transporting this waste to landfills produces leachate, which causes harmful heavy metal pollution. In this study, seven soil sampling stations were established at Shiraz Engineering Landfill, with five additional stations near residential areas. Sampling occurred during low and high rainfall seasons. The Aqua Regia method determined heavy metal concentrations. The share of these heavy metals in landfill soil was as follows: 42.20% for Ni, 29.06% for Cr, 17.42% for Cu, 7.24% for Co, 3.95% for As, and only 0.13% for Cd metal. The average pollution load index in the analyzed soils was 2.58 and it showed the High level of pollution of these soils. The ecological risk index for residential areas and most landfill locations (excluding the recycling plant) fell within the low pollution category. The results of the non-carcinogenic risk assessment indicated that the hazard index (HI) for all heavy metals in the soil samples of the study area was 0.3933 for children and 0.0854 for adults. These values suggest that workers at the landfill site and children and adults residing near the site are not exposed to short-term risks associated with heavy metals. The chronic and long-term carcinogenic risk (TCR) for the studied heavy metals in the landfill soil exceeded the threshold of 1×10-4 for both adults and children, indicating an unacceptable and dangerous risk to human health. For soil samples from residential areas, the TCR value for children was 1.30×10-4, indicating the risk of carcinogenesis specifically for children.
