Study on Tributyltin Chloride Accumulation Factors in Fish Tissue by Analysis of Variance

n this article, statistical survey has been used to investigate effective parameters of tributyltin chloride bioaccumulation in food in one of the native fish species of Persian Gulf, Scat fish (Scatophagus argus), within a time period of 21 days at marine simulated aquarium bioassay. The Design Expert software (ver. 7) was applied for statistical analyzing the effects of biocide concentration in food and exposure time on compound concentration variations in fish tissues. Effects of concentration on the amount of absorption and accumulation of TBT were significant. The results show that there is relation between these factors. The results of the statistical analysis illustrate that exposure process is more sensible to the exposure time than to concentration ofthe biocide. The results present that body of fishes resist against biocide at limited period, and cellular metabolism controls the amount of bioaccumulation of biocide for a while, but bodies would lose their abilities and bioaccumulation would increase instantly and rapidly. The results have been improved by a modified cubic experimental model.
