The highest BCF for edible portions of Salmo gairdneri was 25.9.
A bioaccumulation in fish study is available for one of the streams in this category. Walsh et al (1977) conducted a 56 day flow through test, with analytical confirmation of exposure concentrations, to determine the bioaccumulation of xylenes by Salmo gairdneri. After 56 days the concentration of xylene in the edible portions of the fish was measured. By comparing the concentrations measured in the edible portions with the exposure concentrations, we have calculated BCF from the data reported by the authors. The highest BCF was 25.9. There was no significant difference in the concentrations measured in the edible portions of the fish after 1 or 56 days exposure, nor at the different exposure concentrations. We can therefore conclude that the bioaccumulation is initially rapid but that after this time the amounts bioaccumulated do not increase with exposure duration.
