Concentrations of BaP metabolites.
(a) Controls, (b) and (c) live and dead algal cells of S. capricornutum and (d) chlorophyll a extracted from S. capricornutum. The initial concentration of BaP was 100 μg L−1. Control, blank culture medium; cis-4,5-diol, BaP-cis-4,5-dihydrodiol; 1,6-dione, BaP-1,6-dione; 6,12-dione, BaP-6,12-dione. Mean ± SD, n = 3
