Effects of benzo (a) pyrene on blood components, tumor markers, and oxidative status in mice.
Benzo (a) pyrene levels were exceeded the permissible limits in 15% and 55% of Tilapia and Mullet samples, respectively [8].
PAH standards contain 500 ppm fluorene, phenanthrene, pyrene, benz[]anthracene, benzo[b]fluoranthene, benzo[]pyrsne, benzo [g,h,i]perylene and indeno[1,2,3-cd]pyrene.
They revealed that linear-type benzo [g]coumarins give similar substitution-induced property changes like parent coumarins, and the fluorescence property is suitable for bioimaging application over the others (very poor or no fluorescence from the benzo[f/h] coumarin in aqueous media).

About a year and a half ago, Camilo Benzo, CICP, manager of global credit and collections with gaming manufacturer IGT of Reno, NV, began noticing something different was happening in the way international banking relationships were working with customers overseas, in that they weren't working that well.
Numerous PAHs, including benz[a]anthracene, benzo[a] pyrene, benzo[b] fluoranthene, benzo [j] fluoranthene, benzo[k] fluoranthene, chrysene, dibenz [a,h] anthracene, and indeno [1,2,3-c,d] pyrene, were responsible for tumors in laboratory animals when they breathed these substances in the air (David, 1990).
As shown in Figure 1, 36 key PAHs are analyzed in just 32 minutes and all priority compounds--including benz [a] anthracene, chrysene, benzo[b]fluoranthene, benzo[a]pyrene, chrysene, triphenylene, cyclopenta[cd]pyrene, and benzo [b], [k], [j], and [a] fluoranthenes--are well resolved allowing accurate integration.
