“…Similarly, we have also previously reported higher Pb and Zn of 8.44 and 56.71 μg g −1 , respectively, in the fleshy tissues of cape horse mackerel in polluted Durban South (Debipersadh et al 2018 ), than reported in the current study. These values were comparable to similar fish species caught in coastal water of Turkey (Mutlu et al 2012 ), but lower than those caught in polluted coastal estuaries and habors (Angel et al 2010 ; Vilches et al 2019 ).…”

“…Fish are one of the main sources of protein for human diet worldwide, but they are also known as being the largest bioaccumulators of HMs due to their position at the top of the food web/food chain in both freshwater (Thompson et al 2012 ) and marine ecosystems (Hernández-Almaraz et al 2014 ; Vilches et al 2019 ). High content of HMs, including both transitional metals and metalloids, can have potential adverse effects on human health and the environment.…”

The bioaccumulation of heavy metals (HMs) in marine fish is a growing global concern due to potential human health risks. The study analyzed HM in the muscle tissue, gills, and gut of adult male and female cape horse mackerel and slinger seabream caught in the polluted Durban Basin and pristine Cape Vidal from April 2018 to February 2019. Results revealed interspecific, spatial, and organ-specific variability in HM levels. In the Durban Basin, slinger seabream had bioaccumulation (in mg/kg) of As (2.3 ± 0.2), Cr (2.6 ± 0.2), Ni (2.0 ± 0.1), and Pb (4.1 ± 0.3) while cape horse mackerel had Ni (1.6 ± 0.2), Pb (4.7 ± 0.6), and Zn (52 ± 3.01) exceeding World Health Organization (WHO) regulatory limits. Metal pollution index (MPI) values were also higher in Durban Basin (> 5.13) than Cape Vidal (< 3.32) for both species’ muscles. Liver and gills of slinger seabream and gut of cape horse mackerel exhibited higher HM accumulation patterns proportionate to the environmental concentrations, indicating the bioindicative potential of HM pollution by the two species. Risk assessment indicated that both fish species had target hazard quotient > 1 for Cr, and target cancer risk < 10–4 for Pb, implying significant potential non-carcinogenic and carcinogenic health risks associated with fish consumption from the Durban Basin. The study recommends daily consumption limits of 16 g/day for slinger seabream and 14 g/day for cape horse mackerel to ensure health safety. The findings contribute to the understanding of HM pollution in the Durban Basin and provide important information for decision-makers and policymakers in developing effective strategies to mitigate and manage HM contamination in fish populations.

“…The Durban basin, which is home to South Africa's largest and busiest port in terms of cargo values, as well as an economic hub that supports numerous manufacturing, petrochemical, sea trade, and transport industries (Goble et al 2014), has experienced the impact of rapid industrial and urban development, coupled with associated ancillary activities, on heavy metal (HMs) pollution of the KZN coastal environment. This issue has been an area of increased research interest (Moloney et Marine shes are one of the main sources of protein for human diet worldwide, but they are also the known as being the largest bioaccumulators of HMs due to their position at the top of the food web/food chain in both freshwater (Thompson, Dunne & Woodward, 2012) and marine ecosystems (Hernández-Almaraz et al 2014; Vilches et al 2019).
