【摘要】 本文介绍了用¹⁸F示踪剂研究氟在罗非鱼体内的行为。罗非鱼通过消化道、鳃和体表（表皮）摄取水中的氟、经过血液迅速扩散分布至全身。由于组织结构、功能等差异,鱼体各组织含氟量有明显的差异。鳞中含量最高;肝脏、肾脏和心脏中含量次之,肉和脂肪中含量最低。鱼能将摄入体内的氟通过鳃、肾、体表释放到水中,摄入量愈高,释放量愈大。更多还原

【Abstract】 The metabolism of fluorine in Tilapia was investigated by ji using fluorine-lfe! ass tracer. For Tilapia, the fluorine was ta- ,ken from water by digestive system, gills and skin, then spread ’?to whole body. The amount of fluorine-18 accuotul eted in various tissues of Tilapia is considerably different. The highest is in the scale. The lowest is in the muscle and fat. The middle is in the liver, kidney and heart. The excretion of fluorine-18 is released into water body by kidney, gills and skin. The more it was taken, the more it was released.更多还原
