摘要

We appreciate the chance to respond to the letter submitted by A. Katsoyiannis, and hope that our comments help alleviate any concern or confusion. Partitioning and Bioaccumulation. The bioaccumulation factors (BAFs) reported by Streets et al. were calculated using the most recent fish (2002) and water (2004) data available and are not average BAFs for all sampling years, as implied by the letter-writer. A significant increase in PBDE concentration in lake trout is unlikely to occur in such a short period of time because the lake trout are adults and their body burden is an integrated concentration of contaminants over their lifetime (5-10 years). Thus we feel that our BAF calculations are sound and that it is both appropriate and important to report these BAFs.
