“…Paulino et al [62] has reported higher concentrations of contaminants in the liver of Astyanax fasciatus and Pimelodus maculatus when compared to the gills. Many researches have shown that liver has higher MT content than gills; the result of the present study is in agreement with the results observed by other workers and reported in the literature [63,64].…”

“…The results demonstrated that Cu, Cr, Fe, Zn, and organochlorines were detected in the gills. These species are vulnerable to the effects of pollution, which affects their survival and reproduction along with the rest of the organisms in the food web [4,21].

On the present study, the nourishment and the digestive system of a population of the spotted pimelodid Pimelodus maculatus Lacepède 1803 from a polluted urban river in Argentina were analyzed (Reconquista River, Buenos Aires province). The specimens are characterized by having benthic habits and an omnivore diet. In their intestinal content, a diversity of components was identified. Such components were grouped into ten alimentary items, with dietary variations according to body size while the longitude of the intestine remained proportional to standard length. Microbiological analysis in the gills, stomach and intestine showed the occurrence of Staphylococcus aureus, Escherichia coli and Salmonella sp. Fungi and yeast were also detected. Bacterial accounts were very high both in the analyzed organs as well in water samples. The ecological and sanitary significance of the identified bacteria is discussed.

“…However, eating too much fish can cause a buildup of heavy metals, such as arsenic (As), cadmium (Cd), lead (Pb), mercury (Hg), chromium (Cr) and nickel (Ni). In fact, heavy metals accumulate in different vital parts of smaller fish, including heart, liver and tissues, by different natural or accidental causes (Paulino et al, 2014;Jayaprakash et al, 2015;Dural et al, 2006;Fernandes et al, 2007). As the contaminated small fish species are food source for bigger fish, which are eaten by even bigger fish and so on, this results in bio-accumulation (Malik et al, 2010;Al-Kahtani, 2009).…”

Heavy metals such as arsenic, cadmium, mercury and lead constitute a serious threat to human health. Generally, regular consumption of fish is recommended because it is a good source of omega-3 fatty acids, which have been associated with health benefits. However, flesh of some fish species contains heavy metals in high concentration, which may pose health risk for individuals that consume them in significant quantities. Therefore, over the last few years, evaluation of heavy metals in fish has become a matter of great global concern and especially in Kingdom of Saudi Arabia.The aim of the present work was toassess the concentration of the most toxic heavy metals present in fish caught along the eastern and western coasts of Saudi Arabia, which was achieved through several studies. Results yielded by analyzing 73 fish species and 1,027 edible fish part samples from 12 sampling sitesrevealed considerable variation in metal concentrations across the sampling locations and fish species. Amounts of some of heavy metals were below the maximum allowed limit. Moreover, high hazard index (HI > 10) was obtained for the consumption of some fish species caught at specific sites, which indicates a high probability of consuming populations experiencing adverse health effects.
