“…These variations could be attributed to the closeness of Station 1 to the pollution sources and the higher concentrations of heavy metals observed in both the water and the fish from this station (Obasohan and Eguavoen, 2021). Brilliance and Davies (2023) reported similar results on the hazard implications of higher concentrations of heavy metals concentration in swimming crab (Callinectes amnicola) consumed from polluted creeks in the Niger Delta.…”

“…(Ihunwo et al, 2022). Children are more susceptible to the toxic effects of heavy metals due to their lower body weight and developmental stage (Anyanwu and Chris 2023). However, several studies have reported similar health risks associated with metal contamination in the Niger Delta region (Abarshi et al, 2017;Dirisu et al, 2019;Nnaemeka, 2020).…”

Anthropogenic activities have caused toxic metals to escalate, polluting rivers, and accumulating in water, sediments, and fish. This harms aquatic ecosystems and has enduring impacts on humans and aquatic life. The study aimed to assess the accumulation of heavy metals (Pb, Cr, Cu, Fe, Ni, Cd, and Zn) in Redbelly tilapia (Coptodon zillii) and water obtained from three sampling stations along Atuka Creek which is a crude oil-contaminated site in a southern creek in Nigeria. The investigation further intends to evaluate potential health risks linked to the consumption of C. zillii and to analyze the pollution and productivity levels of the corresponding aquatic ecosystem. The results show significant variations in heavy metal concentrations across stations, with Station 1 exhibiting the highest contamination levels attributed to its proximity to pollution sources. The fish from Station 1 revealed elevated levels of contamination, surpassing recommended limits for Pb, Fe, Ni, and Zn. Calculations of chronic daily intake (CDI) values indicate potential health risks for both adults and children, particularly in Stations 1 and 2. The hazard quotient (HQ) and hazard index (HI) values surpassed safe limits in these stations, suggesting non-carcinogenic health risks linked to fish consumption and swimming. Moreover, lifetime cancer risk (ILCR and TLCR) assessments revealed an augmented risk of cancer, especially in Stations 1 and 2. These findings emphasize the need for stern pollution control measures, regulations, and remediation strategies to mitigate heavy metal contamination, ensure water quality, and safeguard public health in southern Nigerian communities.

Marine biotas are used to assess potential adverse human health risks associated with consuming protein-rich aquatic organisms. Heavy metal content of Mangrove oysters (Crassostrea gasar) was evaluated between January and June 2022 in 3 stations. Six heavy metals (copper, cadmium, zinc, lead, arsenic and iron) were determined using standard methods. Target Hazard Quotient (THQ) and Hazard Index (HI) were used for the non-carcinogenic assessment while Target Cancer Risk (TR) was used for the carcinogenic assessment of the potential human health risk of consuming the oysters. The heavy metal values recorded were Cu (473.2 – 596.7 mg/kg), Cd (2.33 – 3.84 mg/kg), 209.02 – 246.41 mg/kg), Pb (6.16 – 12.07 mg/kg), As (0.012 – 0.016 mg/kg) and Fe (1609.0 – 1846.0 mg/kg). All the heavy metals were above the acceptable limits except arsenic. Stations 2 and 3 had relatively higher values; attributed to anthropogenic activities. The THQ and HI values were less than 1 in all the metals and stations while TR for Pb and arsenic were within the negligible range in all the stations. However, Cd was unacceptable among the children in station 2. Station 3 had relatively higher values while the children were more vulnerable to both non-carcinogenic and carcinogenic risks. In conclusion, the consumption of oysters from Elechi Creek is considered safe based on acceptable levels of the THQ, HI and TR; though Cd-TR for children (Station 2) was unacceptable.
