“…In addition, the Levene’s test with the significant level at p ≤ 0.05 was adopted to determine the homogeneity of variances in terms of ANOVA tests. Correlation matrix (CM) and principal component analysis (PCA) were performed to determine the correlations and association between heavy metals in the studied fish species [34]. The correlation matrix used to analyze heavy metals could result in both positive and negative outcomes [35–38].…”

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.

“…Exposure to Heavy Metals. Estimated daily intakes (EDIs) of heavy metals for coastal people through seafood consumption were calculated using the following formula and is expressed as μg per kg of body weight per day (μg kg -1 BW day -1 ) [2,18]:…”

“…The RfD values for Cd, Cr, Cu, Zn, and Hg were 1, 3, 40, 300, and 0.3 (μg kg -1 BW day -1 ), respectively [24]. The RfD value for Pb is actually under discussion [2,3], so for its risk calculation, we used the value from Hang et al [25], i.e., 3.5 μg kg -1 BW day -1 .…”

“…If the THQ value of heavy metal was less than one, it was assumed to not pose risk of noncarcinogenic effects (e.g., reproductive toxicity, teratogenicity, or liver toxicity) for humans over lifetime exposure. The estimates involved in these calculations present uncertainties; therefore, THQ values between one and ten may indicate a chance of noncarcinogenic effects, with an increasing probability for the occurrence of these effects as the value of THQ increases [2,3,25].…”

“…Aquatic organisms, including cockle in this ecosystem, can accumulate toxic metals which can pose a significant impact on human health due to the consumption of contaminated cockle. Heavy metals are nonbiodegradable toxic contami-nants and may cause severe damage to the liver, kidney, central nervous system, mucus tissues, intestinal tract, and reproductive systems at high levels [1][2][3].…”

This study reports the presence of Cd, Pb, Zn, Hg, Cu, and Cr in the cockles (Anadara granosa, Linnaeus, 1758) harvested along the East Java Coast, Indonesia. The concentrations of metals were determined by atomic absorption spectrometer and expressed in mg kg -1 wet weight. The concentrations of metals ranged from 0.11 to 0.82 mg kg −1 for Cd, 0.10 to 0.54 mg kg −1 for Pb, 10.22 to 19.04 mg kg −1 for Zn, 0.02 to 1.47 mg kg −1 for Hg, 1.79 to 4.76 mg kg −1 for Cu, and 1.64 to 3.79 mg kg −1 for Cr. The metal concentrations in the whole tissues of cockles were in the order Zn>Cu>Cr>Hg>Cd>Pb. The Cd and Pb levels in cockles were found to be higher than the permissible limit for human consumption according to EC and FAO; the levels of Hg exceeded the EC, Hong Kong, Australia, and Indonesia standards; and the levels of Cr exceeded the Hong Kong standard. The estimated weekly intake (EWI) of cockles indicates that the concentrations of Cd and Hg in the cockle tissues from Gresik were higher than the provisional tolerable weekly intake (PTWI); meanwhile, the concentrations of Cr of cockles from all locations were higher than and close to the PTWI. The THQ values for Cd at Gresik, for Hg at Gresik, Surabaya, and Pasuruan, and for Cr at all locations were higher than one indicating that these metals pose potential noncarcinogenic effects to consumers. Reducing the consumption of cockles should be done in order to minimize the adverse effects of metals especially Cd, Hg, and Cr to human health.
