Lipid normalized 2-ethylhexyl 2,3,4,5-tetrabromophthalate (TBPH, black bars) and 2-ethylhexyl 2,3,4,5-tetrabromobenzoate (TBB, white bars) concentrations in fish collected on day 0 (initial) and on day 56. Control, Firemaster 550®, and Firemaster BZ-54® (Chemtura,) treated fish were analyzed. Bars illustrate the mean and the standard error of mean (n=3–4). Asterisk denotes significance (t test; p<0.05). ND=Nondetect (3 times the blank value;<0.152μg/g lipid for Initial and<0.212μg/g lipid for Control).
