“…The Cd level was lower than those observed in the fish species of the Santa Maria Bay (1.52–14.09) [ 58 ], while higher than the values displayed for other fish in the Red Sea [ 59 ], the SE coast of India [ 57 ], and the Bay of Bengal [ 60 ]. However, the results of Cd in analyzed samples were in line with the study conducted in the oil-spilled area and the Red Sea [ 61 ]. The mean Cd concentrations in the muscles of individual fish species were in the range of permissible limits [ 62 ].…”

Gadani shipbreaking area, located on the coastline of Pakistan, is an important fish production area. In this study, levels of four metals (Ni, Pb, Cd, and Mn) in 148 muscle and gill samples of seven fish species (Small-scale terapon, Torpedo scade, Sicklefish, Saddle grunt, Gold silk seabream, Indian mackerel, Spotted sickle fish) and seawater samples, taken from 9 sampling sites in the shipbreaking area, were determined. In addition, multiple approaches were used to assess human health risks from fish consumption. Trace metal concentration in seawater ranged from 0.05 to 1.96 mg/L in shipbreaking vicinity and 0.03 to 0.97 mg/L in the reference site (Miani Hor). However, metal accumulations in fish species ranged from 1.33 to 5.26 μg/g. Among trace metals, the level of Pb in all fish species was highest, followed by Ni, Mn, and Cd. The bioaccumulation factors (BAFs) for both gills and muscles displayed the order: Mn > Cd > Ni > Pb. Estimated daily intake (EDI) values were below the tolerable daily intake (TDI). Based on target hazard quotient (THQ), the investigated fish species were safe regarding Pb and Mn (THQ < 1), while they may cause potential risk regarding Cd and Ni (THQ > 1). After comparison with maximum permissible limits, heavy metal concentration in the edible muscle tissues of all the analyzed fish species from the Gadani coast were found safe for human consumption.

“…While Cd was not detectable, Pb concentrations in the samples from the Finima Creek were 100 times higher than the maximum level and four times higher than those in fish from the Bonny River. The authors attributed the high metal concentrations to the frequent oil spills and industrial effluents discharged into these rivers and the Finina River [ 90 ]. These creeks are known for pollution from oil spills and various forms of anthropogenic activities.…”

“…Similarly, Abarshi et al, (2017) [90] assessed the presence of Cu, Ni, Zn, Pb, Mn, Fe, and Cd in the organs (liver, gills, and muscle) of fish samples obtained from the Finima Creek and Bonny River in Rivers State. High concentrations of heavy metals were found in fish samples from the two areas, while the highest concentrations were in the fish from the Finima Creek.…”

Pollutants in aquatic food are a major global concern for food safety and are a challenge to both national and international regulatory bodies. In the present work, we have reviewed available data on the concentrations of polycyclic aromatic hydrocarbons (PAH), persistent organic pollutants, metals, and microplastics in freshwater and marine fish in Nigeria with reference to international maximum levels for contaminants in food and the potential risk to human health. While most of the contaminant levels reported for fish do not imply any health issues, iron and lead may represent potentially toxic levels in fish from specific areas. Studies on PAHs in marine fish are scarce in Nigeria, and the main focus is on the environmental pollution caused by PAHs rather than on their presence in food. The findings suggest that the consumption of smoked Ethmalosa fimbriata poses a higher potential carcinogenic risk than the other fish species that were investigated. Most of the other studies on PAHs in smoked fish are focused on the smoking method, and little information is available on the initial level of PAHs prior to the smoking process. Metal contamination in fish appeared to be affected by mineral deposits in the environment and industrial effluents. In general, heavy metal levels in fish are below the maximum levels, while there is limited data available on POPs of relevance to food safety in fish from Nigeria, particularly in terms of dioxins, brominated flame retardants, and fluorinated compounds. Furthermore, there is currently limited information on the levels of microplastics in fish from Nigerian waters. This work revealed the need for a more systematic sampling strategy for fish in order to identify the most vulnerable species, the hot spots of contaminants, and applicable food safety control measures for fish produced and consumed in Nigeria.

“…It could also be related to the fact that Tigris River in this region is not polluted to a degree that can cause bioaccumulation of these metals in fish muscles, because manufactories, industrial plants or mining processes are not present on the river yet near the fishing site. Another reason which can contribute is that the fish muscles accumulate the least amount of heavy metals if compared to active metabolite organs as gills, liver and kidney (Balasim,2013), (Abarshi,et al, 2017), (El-Moselhy,et al,2014), (Nwani, et al, 2009),the muscle tissue usually has the lowest metal levels in fish (Mohammadnabizadeh,et al, 2014). The maximum permissible limits of heavy metals (Cu, Fe, Mn, Zn) in fish muscles (ppm) according to international standards; FAO 2003retrieved 2012, WHO 1996, FAO/WHO 1989, FAO 2009, WHO 1999and WHO 1993 are given table 7.…”

In this study, the concentrations of some heavy metals including Al, Cu, Fe, Mn, Zn, Cd, Co, Cr, Ni and Pb were determined in the muscles of three commercial fish species available in Duhok city markets in two seasons, using inductively coupled plasmaoptical emission spectrometry (ICP-OES), after the wet digestion process. Lowest and highest mean values of metals in µg/g (dry weight) were as follows: Al: Under Detection Limit (UDL)-3.71, Cu: UDL-4.00, Fe: 5.40-21.44, Mn: UDL-3.45, Zn: 13.38-140.11, while Cd, Co, Cr, Ni, and Pb were not detected. The highest levels of Al, Fe and Zn were recorded in Shukhat fish species, and the highest levels of Cu and Mn were recorded in Shabout in the winter season. The highest level of all metals was recorded for Zn (172.8 µg/g) with the highest mean value of (140.11 µg/g) in Shukhat species during winter. Most heavy metal concentrations were below the international permissible limits for fish, however, some of the maximum and mean values of metals were above the international standards. Fe concentrations were above the maximum allowable limits set by WHO (1999). Zn concentrations were above the maximum permissible limits set by joint FAO/ WHO (1989) and FAO (2012).
