“…Hence, there is no potential non-carcinogenic effect for the consumers due to intake of the fish species. Studies carried out by several authors in similar conditions were in line with our results [32, 69, 111–113]. In general, the assessment of THQ for human health risk evaluation has no dose-response relation of the examined elements [114].…”

The Karnaphuli River estuary, located in southeast coast of Bangladesh, is largely exposed to heavy metal contamination as it receives a huge amount of untreated industrial effluents from the Chottagram City. This study aimed to assess the concentrations of five heavy metals (As, Pb, Cd, Cr and Cu) and their bioaccumulation status in six commercially important fishes, and also to evaluate the potential human health risk for local consumers. The hierarchy of the measured concentration level (mg/kg) of the metals was as follows: Pb (13.88) > Cu (12.10) > As (4.89) > Cr (3.36) > Cd (0.39). The Fulton’s condition factor denoted that fishes were in better ‘condition’ and most of the species were in positive allometric growth. The bioaccumulation factors (BAFs) of the contaminants observed in the species were in the following orders: Cu (1971.42) > As (1042.93) > Pb (913.66) > Cr (864.99) > Cd (252.03), and among the specimens, demersal fish, Apocryptes bato appeared to be the most bioaccumulative organism. Estimated daily intake (EDI), target hazard quotient (THQ), hazard index (HI) and carcinogenic risk (CR) assessed for potential human health risk implications suggest that the values were within the acceptable threshold for both adults and children. However, calculated CR values indicated that both age groups were not far from the risk, and HI values demonstrated that children were nearly 6 times more susceptible to non-carcinogenic and carcinogenic health effects than adults.

The Karnaphuli, a major river of Bangladesh, located off the coast of Chittagong in the Bay of Bengal is largely exposed to the heavy metal pollutants, which may be toxic to humans and aquatic fauna. The estuary is a striking example of a site where human pressure and ecological values collide with each other. In spite of being a major supplier of fish food for local community, there has been no study carried out to date to assess the potential human health risk due to heavy metal contamination in the fish species from this estuary. Therefore, the aim of present study was to assess bioaccumulation status and the potential human health risk evaluation for local consumers. Six commercially important fish species, Apocryptes bato, Pampus chinensis, Hyporhamphus limbatus, Liza parsia, Mugil cephalus, and Tenualosa toil from the Karnaphuli River estuary were collected to analyze heavy metals concentration level. Heavy metals As, Pb, Cd, Cr and Cu were detected from the samples using inductively coupled plasma mass spectrometry (Model: ELAN9000, Perkin-Elmer, Germany). The hierarchy of the measured concentration level of the metals was as follows: Pb (mean: 13.88, range: 3.19 - 6.19) > Cu (mean: 12.10, range: 10.27 - 16.41) > As (mean: 4.89, range: 3.19 – 6.19) > Cr (mean: 3.36, range: 2.46 – 4.17) > Cd (mean: 0.39, range: 0.21 - 0.74). The Fulton’s condition factor denoted that organisms were particularly in better ‘condition’ and most of the species were in positive allometric growth. The Bioaccumulation factors (BAFs) observed in the species of the contaminants were organized in the following ranks: Cu (1971.42) > As (1042.93) > Pb (913.66) > Cr (864.99) > Cd (252.03), and among all the specimens, demersal fish, A. bato corresponded to the maximum bio-accumulative organism. Estimated daily intake (EDI), target hazard quotient (THQ) and carcinogenic risk (CR) assessed for human health risk implications suggest that the values are within the acceptable threshold for all sorts of consumers. Hence none of them would experience non-carcinogenic and carcinogenic health effect for the ingestion of the fishes. However, children are shown to be largely susceptible than adults to non-carcinogenic and carcinogenic health effect due to the consumption of fish. Therefore, an appropriate guidlines and robust management measures needed to be taken to restore the estuarine health condition for greater benefit of the quality of fish products for local consumption.Graphical abstract

“…have resulted in aquatic environmental pollution [29][30][31][32]. Heavy metals, originating from natural as well as anthropogenic sources, continually enter the aquatic environment and pose serious threats to human health due to the tendency of metals to bioaccumulate and to persist due to metals being unable to be metabolized or chemically consumed [30,[33][34][35][36][37][38]. Some metals are essential (e.g., Cu, Fe, Zn), while others (e.g., Cd, Pb, Hg) are non-essential yet can compete with essential metals for transport and utilization and are highly toxic to organisms [39].…”

Although fish are often recommended as a component of a healthy diet, the environmental accumulation of heavy metals in many fish species has been of considerable concern for those weighing the nutritional health benefits against adverse toxic outcome of excess intake of toxic metals. This study aimed to determine the concentration of essential and toxic metals in the tissues of Catla catla in Mangla Lake and to assess the possible risk to the consumers. Fifty samples of Catla catla were collected from Mangla Lake, Mirpur, Azad Jammu and Kashmir, Pakistan and analyzed for eighteen metals including essential and trace metals. The measured range concentrations (µg/g, wet weight) in muscle tissues, in decreasing order, were: K (955–1632), Ca (550–2081), Na (449–896), Mg (129–312), Zn (61.2–215), Fe (11.6–26.8), Sr (2.60–9.27), Pb (1.72–7.81), Se (1.55–3.55), Co (0.12–4.08), Mn (1.04–4.33), Ni (0.69–3.06), Cu (0.88–2.78), Cr (0.45–1.88), As (0.67–1.58), Cd (0.28–0.56), Hg (0.17–0.57) and Li (0.12–0.38). The metal concentrations found in this study were comparatively higher than those reported in literature. A majority of the metals exhibited higher accumulation in gills compared with those in scales and muscles. Mean levels of Pb, As, Co, Mn, Cd, Cr and Zn in Catla catla muscle were found to be exceeding the international permissible limits for the safe human consumption. The condition factor (K), as an indicator of fish health status, indicated that Catla catla of Mangla Lake are in good health condition. The metal pollution index (MPI) of gills (27.9), scales (12.5) and muscle (7.57) indicated low contamination. Moreover, human health risk was evaluated using estimated weekly intake (EWI) and daily intake (EDI), target hazard quotient (THQ), hazard index (HI) and target cancer risk (TCR). Estimated weekly and daily intake values for As, Cd, Cr, Hg, Ni and Pb were higher than provisional permissible tolerable weekly intake and permissible tolerable daily intake while THQ for As, Cd, Cr, Hg, Pb, Se and Zn was higher than 1. The THQ for As, Hg and Pb was several folds higher than 1, indicative of lifetime non-carcinogenic health risks to the consumers. The hazard index indicated cumulative risk, which greatly increased with increasing fish consumption. Target cancer risk indicated that the people eating the Catla catla from Mangla Lake were exposed to As, Cd, Cr, Ni and Pb with a significant lifetime carcinogenic risk. In summary, consumption of Catla catla from this lake was found to be associated with an increased lifetime risk to the general health of the consumers.
