Abstract: | Fish is a vital, healthy source of animal protein and vitamins. This study was oriented to estimate fluoride, some selected elements, lipids, and protein concentrations in fish. Five fish species were collected from the Egyptian Mediterranean Sea coast during April 2007. Variable content of fluoride, calcium, magnesium, sulphate, phosphorus, lipids, and protein were determined in muscle and liver of fish samples and yielded average values in fish muscle of 11.0 ± 2.0 μg/g, 6.5 ± 3.8 mg/g, 100.2 ± 39.3 mg/g, 4.4 ± 6.3 mg/g, 2.4 ± 0.5 mg/g, 6.0 ± 2.2 mg/l, and 2.6 ± 1.0 g% wet wt, respectively. Special attention was given to fluoride because of its hazardous classification. Interestingly, the hazard index values of fluoride were less than 1 for all collected fish species. Additionally, the daily fluoride exposure was generally below the nutrient reference values for Australian and New Zealand populations. Accordingly, there is little human health risk from the selected fish species due to consumption of fluoride-contaminated fish. |
