“…Many studies have been conducted on heavy metal pollution in developed countries' food chains [13][14][15][16]. However, some studies have been conducted in developing regions [17][18][19][20]. In Pakistan, published data on heavy metal contamination in the food chain are not substantial, a few reports for references [21][22][23][24][25][26][27].…”

The consumption of contaminated vegetables has a great impact on human health. Due to this fact, we conduct the study to estimate the heavy metals in groundwater, soil, and vegetables by using the atomic adsorption spectroscopy (AAS) and find out the health risk using THQ and TCR caused by using these vegetables. The mean concentrations of As (0.015–0.40 mg/L), Cd (0.02–0.029 mg/L), Co (0.31–0.38 mg/L), Cr (1.02–1.09 mg/L), Cu (2.14–2.17 mg/L), and Hg (0.01–0.04 mg/L) are high in groundwater from threshold values given by WHO. The mean concentrations of As (22.17–23.14 mg/kg), Cd (4.21–4.54 mg/kg), Cu (21.24–24.36 mg/kg), and Pb (32.12–33.48 mg/kg) are high in soil samples from threshold values given by WHO. The mean concentrations of As, Cd, Pb, Cr, Fe, Hg, and Mn values exceeded the recommended values with concentration ranges: 1.75–4.56, 0.41–0.67, 2.12–3.12, 1.44–4.56, 87.12–135.25, 2.09–2.64, and 33.41–129.32 mg/Kg, respectively. The vegetable sample’s average concentration of heavy metals was in decreasing order cabbage ˃ brinjal ˃ okra ˃ tomato. The EDI values for As, Co, and Hg calculated for both adults and children is high. The target hazard quotients (THQ) for As, Co, and Hg are greater than the threshold value by consuming vegetables, which indicated the health risk for both adults and children. Similarly, HI due to tomato, cabbage, okra, and brinjal’s consumption is ˃ 1, with HI values 8.1975, 15.3077, 8.7312, and 10.2306, respectively. This advised the possible health effect in this area by using these vegetables. Target Cancer risk (TCR) exposed the adverse cancer risk persuaded by As, Cr, and Hg as their values exceeded the normal range by USEPA by consumption of these vegetables. This study concluded that vegetables imply the total health risk on local people, and regular monitoring of heavy metals is strongly suggested in this region.

“…According to Tapos et al, [41], in a study carried out on the concentrations of Heavy metals in foods, observed that the risk of Arsenic (As) as a carcinogen was higher than the USEPA standard (10 -4 ), indicating increased risk of cancer for adults and children who patronized such foods in the study area.…”

“…Thereafter, the hazard index (HI) was calculated using Equation 8. Based on the USEPA ( 2007) guidelines, it was reported that HI < 1 is assigned for no health risk is expected to occur, whereas HI ≥ 1 is assigned for moderate or high risk for adverse human health effects (Ali et al 2019;Idris et al 2019;Ukah et al 2019;Kormoker, Proshad, Islam, Shamsuzzoha, et al 2020;Proshad et al 2020;Shams et al 2020).…”

“…Heavy metals such as Cr, Ni, Cu, As, Cd and Pb are considered to be systemic toxicants, recognized to trigger multiple organ harm even at trace amounts and to capability of bioaccumulation in the major human body systems (R. . For instance, high intake of Cr and As throughout consumption of contaminated water and foodstuff may cause genotoxic carcinogen (Khan et al 2015;Kormoker, Proshad, Islam, Shamsuzzoha, et al 2020). Ni ingestion can also cause fatal cardiac arrest and hypertension (Knight et al 1997).…”

Louhajang River, Bangladesh, crosses Tangail, which is a densely industrialized and urbanized city. Louhajang River is an essential water source for domestic, irrigation, and urbanization purposes. This study reports the levels of pH, electrical conductivity (EC), and some toxic heavy metals in 40 water samples collected during summer and winter seasons from Louhajang River. The levels were found to be in the ranges of pH 6.22-7.43 and EC 345-798 mS/cm, Cr 0.18-13.2, Ni 0.02-19.04, Cu 0.96-15.92, As 2.18-12.51, Cd 0.02-2.42, and Pb 0.49-15.74 µg/L. The winter season reported higher levels of the examined parameters than the summer season with significant variation (p < 0.05) for all parameters, with the exception of Cd. The metal contents were assessed against local and international standards for drinking, irrigation and aquatic life purposes where different trends were observed. The heavy metal evaluation index (HEI) and the ecological risk index (ERI) reported low to moderate risks. The spatial distribution of metal contents assigned hot spots in some sites along the riverbed, which were attributed to specific manmade sources. The health risk assessment for three population categories, i.e., adult male, adult female, and children, were examined in terms of hazard index (HI) and total cancer risk (TCR) for oral and dermal pathways during both seasons. Cr and Cd recorded HI more than unit in all cases, indicating possible non-cancer risk. TCR values of As for the three examined population categories during both seasons were > 1.0×10-6, indicating possible cancer risk, while that of Pb were < 1.0×10-6. For Ni, about 10-25% of the sampled sites recorded TCR > 1.0×10-6.
