BIOSIS COPYRIGHT: BIOL ABS. 1. The order of the bioconcentration factors (BCF) in carp at three pH values was pH 7.8 pH 6.8 pH 6.0 for both Bu3SnCl and Ph3SnCl over the 14 days exposure period. 2. There were significant differences (P 0.05-P 0.001) in the BCF values of both Bu3SnCl and Ph3SnCl between the pH values at 1, 3, 7, 10 and 14 days. 3. Partition coefficients between n-octanol and water (Pow) of both Bu3SnCl and Ph3SnCl increased with increasing pH (pH 5.8-8.0). 4. The increase in the BCF values of Bu3SnCl and Ph3SnCl with increasing pH is probably due to the change of the chemical forms (Bu3Sn+ to Bu3SnOH and Ph3Sn+ to Ph3SnOH).
