Significant BaP metabolites in A549 cells supplemented with fatty acids.

<p>BaP (A), 3OH (B), t7,8 (C) and Pyr (D) profiles in cells. A549 cells were incubated with BSA (carrier control), OA, LA or DHA for 48 h prior to addition of 2 µM BaP for 24 h. Data represent mean ± SEM of fluorescence intensity of significant metabolites: A) BaP, B) 3OH, C) t7,8, and D) Pyr measured in at least 30 images per treatment with at least 30 cells per image. Letters above the bars represent significant differences within a treatment for each evaluated metabolite using Tukey test at p<0.05. No significant differences were found in the other metabolites measured (9OH, BPDE or 3,BPQ).
