“…Mean Na-concentrations (29,292 μgL −1 ) of this study is relatively higher than the literature data mentioned in Table 2 , except for the drinking water sources from Rangpur, Bangladesh [ 78 ] and Nigeria [ 79 ]. In contrast, the average concentration of K (2239 μgL −1 ) is relatively lower compared to the literature data, except for Ghana [ 80 ] and Saudi Arabia [ 81 ]. Similarly, the average content of Ca (41,584 μgL −1 ) is higher than in Rangpur, Bangladesh [ 78 ], Ghana [ 80 ], and Saudi Arabia [ 81 ], but lower than in Jamalpur, Bangladesh [ 82 ], France [ 25 ], and Nigeria [ 79 ].…”

“…Moreover, Table 2 also represents the comparison between some existing literature data (Zakir et al, 2020;Saha et al, 2019;Rahman et al, 2013;Bodrud-doza et al, 2020;Kumar et al, 2019;Maw et al, 2020;Abeer et al, 2020;Muhammad et al, 2011;Mohammadi et al, 2019;Qiao et al, 2020;Dong et al, 2020;Nguyen et al, 2020;Le bot et al, 2016;Momot et al, 2005;Szuster-Janiaczyk et al, 2018;Abdeldayem, 2019;Opoku et al, 2020;Egbueri et al, 2020) and the determined heavy metal(oid)s concentrations in the tap water samples of the present study. In comparison to literature data, the mean concentration of Fe, Cr, Pb, Co, Ni, Cd were obtained significantly higher than the tabulated literature data, contrariwise, As concentration in the present study were much lower than the literature data.…”

Tap water is the sole source of water in urban cities but gradually being polluted by potentially toxic elements due to unplanned urbanization. The south Asian megacity, Dhaka (capital of Bangladesh) encounters drastic water pollution resulting mainly from anthropogenic differential factors. Consumption of such polluted water distributed to residents by pipelines can trigger health risks. Therefore, this study investigated the public health vulnerability associated with dissolved metal(oid)s in tap water collected across Dhaka city. The concentrations of Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Cd, Hg and Pb in measured tap water ranged from 8-156, 7–73, 400-20100, 12–110, 7-101, 12–136, 12–908, 0.03–9.75, 1–5, 0.22–1.30, and 8-118 µg/L, respectively. Among the observed elements, Pb, Cr, and Fe concentrations in 18%, 26%, and 75% of sampling sites, respectively, exceeded the standard guideline criteria of Bangladesh. Entropy-based water quality index demonstrated that ~ 12% of sampling sites possessed water unsuitable for drinking and other household works. The dominant sources of water pollution in this region are industrial effluents and domestic sewage. Both non-carcinogenic and carcinogenic health risks are invoked mostly from ingestion of Co and Pb. Regular consumption of this tap water without further pretreatment may result in detrimental health consequences to both children and adults due to the physiological accumulation of toxic elements over time. This study highlighted a comprehensive scenario of the potentially toxic elements in the tap water of Dhaka city, which will allow policymakers to take adequate measures for sustainable water quality management.

“…Though, the total ingested dose of PHEs is not always equal to their percentage of body absorbed pollutant dose in reality since some fraction of the ingested PHEs may be excreted, but the remainder accumulates in body tissues where they can affect human health (Horiguchi et al, 2004;Opoku et al 2020).…”

The study evaluated human health risks associated with the consumption of pumpkin and spinach cultivated around non-mining areas of the Asu River Group. Eighteen samples were collected and analyzed for As, Pb, and Cd, obtaining fifty-four results. The samples were washed with deionized water, air-dried and oven dries at 105°C for 48 hours and analyzed using Varian (USA) Atomic Absorption Spectrophotometer. The concentration of Pb, As, and Cd in the vegetable trend follows; Ebonyi south (ES) < Ebonyi central (EC) < Ebonyi north (EN); EN < ES < EC and ES < EC < EN respectively both for Pumpkin and Spinach vegetables. The Cd, As and Pb, content was below WHO/FAO, (2007) and EU, (2006) specific limits. The daily intake of metals, health risk index, and targeted health quotient were computed. The DIM of Pb, As and Cd were below their respective oral reference dose (RfD) of 0.004, 0.003, and 0.001mg/kg/day. Pb, As, and Cd HRI values for adults, teenagers, and children are in the following order Adult < Teenagers < Children for all samples across the study area. The Pb abundance follows ES < EN < EC in both pumpkin and spinach, and Cd follows EN < EC < EN and EN < ES < EC for pumpkin and spinach respectively. Arsenic HRI in order of EN < EC < EN and EN < ES < EC for pumpkin and spinach respectively. On average, HRI of Pb, As and Cd ranges from 0.00312 to 0.0663, 0.00411 to 0.238 and 0.009 to 0.331 mg/kg/bw/day for the vegetables. The HRI and THQ for adults and teenagers were all < 1 for As, and Pb while Cd THQ > 1 in pumpkin from ES.
