Background

Heavy metal contamination has become a serious issue in this century especially detected in fish organs. Due to the presence of radioactive compounds in agricultural and sewage effluent, which destroys aquatic ecosystems, threatening human livelihoods. Health hazards associated with low and high consumption consumers assessed in five commercial fish species collected from Hurghada City, Egypt, during winter and summer, 2020. Atomic absorption spectrophotometer technique used for determination heavy meals in different organs and expressed as μg/g wet weight.

Results

Heavy metal concentrations in muscle ranged between:(0.054–0.109), (0.260–1.043), (0.264–0.897), (5.895–11.898), (0.381–0.970), (13.582–29.133) and (0.332–0.589) µg/g for Cd, Pb, Mn, Zn, Cu, Fe and Ni respectively, which were lower than those of gills and liver. These concentrations were within WHO, FAO/WHO, and EU standards. Consumption of edible species was lower than the (TDIs) established by the (JECFA) and Egyptian Standards. Even though THQ and TTHQ values were < 1 while, in children with highly consumer were> 1.

Conclusion

This study concluded that intake of Red Sea fish is safe for human health. It is critical for consumers to be aware of the consequences of excessive fish consumption, particularly children with highly consumer, which represent possible health risks.

埃及红海赫尔格达市不同食用鱼类中重金属的生物积累和健康风险评估

背景

重金属污染在本世纪已成为一个严重的问题，特别是在鱼类器官中检测到。由于农业和污水中存在放射性化合物，破坏水生生态系统，威胁人类生计。在 2020 年冬季和夏季，从埃及赫尔格达市收集的五种商业鱼类中评估了与低消费和高消费消费者相关的健康危害。原子吸收分光光度计技术用于测定不同器官中的重餐，以微克/克湿重表示。

结果

肌肉中的重金属浓度范围为：(0.054–0.109)、(0.260–1.043)、(0.264–0.897)、(5.895–11.898)、(0.381–0.970)、(13.582–29.133) 和 (0.332–0.589) µg /g分别为Cd、Pb、Mn、Zn、Cu、Fe和Ni，均低于鱼鳃和鱼肝。这些浓度在 WHO、FAO/WHO 和 EU 标准范围内。食用物种的消费量低于（JECFA）和埃及标准制定的（TDI）。尽管 THQ 和 TTHQ 值 < 1，但在高度消费的儿童中 > 1。

结论

这项研究得出结论，摄入红海鱼对人类健康是安全的。消费者必须意识到过度食用鱼类的后果，尤其是消费量大的儿童，这可能带来健康风险。
