摘要

1. 两种化学物质经金鱼鳃摄食后的生物浓度因子(BCF)在接触21天后达到稳定水平。暴露21 ~ 28 d后，Bu3SnCl和Ph3SnCl (N = 2)的平均BCF值分别为1976和1384。2. 金鱼口服Bu3SnCl的BCF值在28天后达到平台，而Ph3SnCl的BCF值没有达到平台。35 d后，Bu3SnCl和Ph3SnCl的BCF值分别为0.04和0.10。3.通过鳃进食与口服进食的BCF值顺序相反。此外，还利用实验结果讨论了这些化合物对淡水鱼的污染。

Accumulation of tri-n-butyltin chloride and triphenyltin chloride by oral and via gill intake of goldfish (Carassius auratus).

1. The bioconcentration factors (BCF) of both chemicals via gill intake of goldfish reached plateaux after 21 days of exposure. The average BCF values of Bu3SnCl and Ph3SnCl (N = 2) were 1976 and 1384, respectively, after 21-28 days of exposure. 2. The BCF values by oral intake of goldfish reached plateaux after 28 days for Bu3SnCl but did not for Ph3SnCl. The BCF values of Bu3SnCl and Ph3SnCl were 0.04 and 0.10, respectively, after 35 days. 3. The order of the BCF values via gill intake was reversed compared with that by oral intake. Further, the contamination of freshwater fish by these compounds was discussed using the results of these experiments.
