“…Consequently, the studied trace elements were not significant enough to reduce cancer risk. Compared to the CR results of other studies [ 43 , 69 , 70 ], this study found a relatively high value of cancer-causing potential to be unlikely, while results obtained from another study [ 71 ] showed a similar value of non-carcinogenicity.…”

To safeguard aquatic environments in and around the Han River watershed in South Korea, a multivariate statistical evaluation of trace elements, a trace element concentration analysis and source determination, and a human health risk assessment were conducted on 10 trace elements at 25 sites. The results demonstrated that the Han River watershed was mainly affected by anthropogenic activities (traffic/industrial activity). The range of concentrations was arranged in descending order: Fe (217.13 ± 301.03 µg/L) > Mn (102.36 ± 153.04 µg/L) > Zn (23.33 ± 79.63 µg/L) > Ba (29.05 ± 12.37 µg/L) > Ni (5.14 ± 11.57 µg/L) > Cu (3.80 ± 3.56 µg/L) > Pb (0.46 ± 0.52 µg/L) > Se (0.06 ± 0.04 µg/L) > Cd (0.01 ± 0.01 µg/L) > Ag (0.004 ± 0.013 µg/L). The hazard index values of trace elements in surface water for combined pathways (ingestion and dermal contact) were < 1.0 for both adults and children, indicating no possible human health hazards. The estimated total cancer risk did not exceed the acceptable limit (1 × 10−4) for adults and children. The findings of this study provide data-driven guidelines for water environment policy decisions in the study area.

“…The spatial distribution pattern of Pb within the lake suggests the likelihood of anthropogenic activities because the recorded Pb levels above the permissible WHO limit were found along the lake banks. The Pb level in this present study is higher than Pb level in Botanga Dam (Asare et al, 2018), Birim River (Emmanuel, 2011), and Owabi reservoir (Akoto et al, 2008), but lower than the Pb level in Pra river (Ebo et al, 2018) and Barekese Dam (Akoto et al, 2019).…”

“…For 30 samples analyzed for total arsenic, 83.33% exceeded the permissible WHO limit of 0.01 mg/L. Although the level of As reported is lower than the level of As in Barekese Dam (Akoto et al, 2019), Ankobra River (Gbogbo et al, 2017), Densu (Gbogbo et al, 2017), and Volta Basin (Gbogbo et al, 2017), the concentration is at a toxic level. Inorganic arsenic is listed as carcinogenic by the USEPA, (1989) and therefore, consumers of the lake water may suffer from arsenic‐related complications such as kidney, lungs and liver cancer, hyperkeratosis, circulatory, and black foot diseases.…”

The total and dissolved lead, cadmium, mercury, nickel, chromium, cobalt, and arsenic in 30 water samples collected from Bosomtwe Lake were analyzed. Arsenic bioavailability was also determined using the ARSOlux test system. Except for chromium, their mean values in the study results exceeded the WHO permissible limit for potability. Cancer and non‐cancer effects associated with exposure to dissolved and total metals by a child and an adult via oral and dermal routes were estimated. The hazard quotient (HQ) values obtained (except adult exposure to total arsenic of 1.71 × 1000) were less than unity. Between child and adult, the recorded hazard index (HI) was 0.82 and 1.75, respectively. The HI results indicate that the adult population is at risk for non‐cancer health effects. Arsenic was the element of concern, and it remained biologically available for uptake by target groups. For child and adult, respectively, arsenic contributed 96.39% and 97.29% to HI values. The risk values for cancer in a child and an adult with oral and dermal exposure to dissolved and total arsenic were lower than the USEPA range. Principal component and cluster analysis identified atmospheric deposition, geogenic, and unregulated application of agrochemicals as plausible sources of water pollution in Bosomtwe Lake. Practitioner points The hazard quotient (HQ) values obtained for adult exposure to total arsenic was 1.71 × 1000. Arsenic remained biologically available for uptake by target groups. The calculated health index (HI) indicated that the adult population is at risk for non‐cancer health effects. Arsenic contributed 96.39% and 97.29% to HI values for a child and an adult. Atmospheric deposition, geogenic, and unregulated application of agrochemicals were the plausible sources of water pollution in Bosomtwe Lake.

“…Heavy metal contamination in the Barekese reservoir through unregulated artisanal mining activities along the offin River (the main feeder stream of the reservoir) can increase to toxic levels and pose threats to the ecosystem and humans who depend on the reservoir's resource [13,14]. In spite of the possible sources of metals pollution in the reservoir, metal levels of fish in the reservoir and their humans' health implications is still not well studied [15].…”

Heavy metal pollution and its resultant accumulation to toxic levels in the Barekese reservoir may threaten human health through the consumption of fish from the Reservoir. The presence and concentrations of arsenic and some other heavy metals (Hg, Pb, Ni, Cr, and Cd) were determined in muscle tissues of widely distributed and highly consumed fish species from the Barekese reservoir using Atomic Absorption Spectrophotometry. A total of 45 fish samples comprising three species (Oreochromis niloticus, Tilapia zilli and Heterotis niloticus) were analyzed for their metal levels. Heavy metals concentrations (mg/kg, w.w) showed varying trends of detection among muscle tissues of selected fish species. However, Hg, Ni, Cr and Cd were detected in muscle tissues of all fish species examined in the study. Indices for non-carcinogenic and carcinogenic risks were estimated for child and adult upon their consumption of fish from the Reservoir. Results of the study indicate a significant level of exposure to Hg, Ni, Cr and Cd through the consumption of fish species from the Reservoir. Health risk assessment also revealed that children are at a relatively higher non-carcinogenic risk through the consumption of metals in Heterotis niloticus (HQ = 2.95 × 10-1). Also, the consumption of all examined fish species from the Reservoir pose no significant cancer risk effects to humans. The present study, therefore, concludes that anthropogenic activities along the Offin River and within the Barekese reservoir’s catchments could lead to deteriorating the quality of fish from the Reservoir hence regular monitoring of such activities is needed.
