内蒙渔业水体及其经济鱼类氟含量的分布特征

Fluorine Distribution in Fishery Water Body and Economic Fishes in Inner Mongolia

2003～2006年，先后调查了内蒙古自治区153个渔业水体的氟含量，并根据其浓度梯度选择了5个试验水体和1个对照水体，分析了其水化学特征及其主要经济鱼类各组织器官的氟含量分布情况。结果表明：内蒙古渔业水体高氟情况普遍；5个试验水体均属于碱性水体，HCO3^-和Cl^-含量均较高；在这些水体中，鱼体肌肉氟含量的顺序为：雅罗鱼〉鲢〉鲫〉鲤；水氟含量越高，则鱼体肌氟含量越高；鱼体各组织器官中，鳍条、骨骼、鳞及鳃的氟含量很高，而肌肉及内脏的氟含量相对较低。

Fluorine contents of 153 fishery waters were investigated in Inner Mongolia from 2003 to 2006. Five experimental water bodies in contrast with Ganggeng Lake were chosen according to water fluoride concentration, and their hydrochemistry characteristic and the fluorine distribution of main economic fish were analyzed. The results showed that the high fluorine water was widespread in Inner Mongolia; the hydrochemistry characteristic of five experimental water bodies was alkalinity water and higher pH with higher HCO3^- and higher Cl^- ; the fluorine content in different fish muscles were： Leuciscus waleckii 〉 Hypophthalmchthys molitrix 〉 Carassius auratus〉 Cyprinus carpio ; fluorine content in fish muscle increased with the increasing of fluorine content in water body ; the fluorine contents in gill, fin, scale and bone were very high, but the fluorine content in muscle and purtenance were relatively lower.
