摘要
本文报道了采用冷原子吸收法,对呼伦池中九种九十尾鱼体中汞含量测定调查结果。总汞含量范围4.69～171.00μg/kg,平均值为42.12μg/kg。九种鱼比较,鲶鱼含汞量最高(88.72μg/kg),其次是鲤鱼(76.35μg/kg),蒙古红鲌和银鲫居第三。白鲢等五种鱼体内汞含量较低,除红鳍鲌、银鲫和蒙古贝氏餐条外,鲤鱼、蒙古红鲌、瓦氏雅罗鱼体内累积的汞量随年龄、体重和体长的增长而升高。
The primary aim of this work is to investigatemercury pollution in fishes in the Huluen Lake, the larges fresh water lakein Inner Mongolia. Ninety fishes in nine spe- cies have been sampled from thelake, Data of total mercury in each fish with determination of cold atomicab-soiption method are in range of 4.69-171.00 μg/kg, and average value 42.12μg/kg, Among the fishes, the highest content of mercury is in Barasilurusasotus (88.72 μg/kg), the second is in Cyprinus carpio heamalopterus (Tem) (75.35 μg/kg), and the next are Erythriculter mongoli-cus and Corassius. However, inrest five species of fishes, mercury contents are lower. In addition, themercury-ac-cumulated contents in the fishes are consistent with their ages, lengths and weights.
