Without surveillance studies on mercury (Hg) levels in predominant fish species and parts eaten in a fishing community, the FAO/WHO guidelines might be surpassed, hence health risk. A monitoring study in a developing country with 29 (Nile tilapia) and 34 (Nile perch) from landing sites provided muscle, bellyfat and liver samples for Mercury detection using Inductive Couple Plasma-optical emission spectroscopy. The study shows that fish eaten in the fishing community are small with fewer risks from mercury. Tilapia accumulated more mercury in muscle and liver than Nile perch. Fish consumed has mercury levels higher than FAO/WHO guidelines, and the bellyfat of Nile perch bioaccumulated more mercury than Tilapia. Based on the above, it is clear that some fish species should not be eaten by the vulnerable groups due to levels of Hg found in the muscle and bellyfat. This research will serve as a base for future studies, sensitization campaigns and policy design on mercury uptake through fish in fishing communities of developing countries.
如果没有对捕鱼社区主要食用的鱼类品种及其食用部位的汞(Hg)含量进行监测研究,那么粮农组织/世界卫生组织的准则可能会被突破,从而带来健康风险。在一个发展中国家进行的一项监测研究中,从上岸点采集了29条尼罗罗非鱼和34条尼罗尖吻鲈,采集其肌肉、腹部脂肪和肝脏样本,采用电感耦合等离子体发射光谱法检测汞含量。研究表明,该捕鱼社区食用的鱼体型较小,汞风险较低。尼罗罗非鱼肌肉和肝脏中的汞积累量高于尼罗尖吻鲈。所消费鱼类的汞含量高于粮农组织/世界卫生组织的准则,尼罗尖吻鲈腹部脂肪中的汞生物积累量高于尼罗罗非鱼。基于以上情况,很明显,由于在肌肉和腹部脂肪中发现的汞含量,弱势群体不应食用某些鱼类品种。这项研究将为未来关于发展中国家捕鱼社区通过鱼类摄入汞的研究、宣传活动和政策设计奠定基础。
