These molecules, in turn, combine and grow into more-complicated structures, such as single-ring benzene and multiring pyrene.
The samples were analyzed at Southwest Research Institute (San Antonio, TX) for pyrene, benz[a]anthiacene, chrysene, benzo[b]fluoranthene, benzo[k]fiuoranthene, BaP, indeno[1,2,3-cd]pyrene, dibenz[a,b] anthracene, and bento[g,h,i] perylene as described by Tonne et al.
To study whether the PAHs increased chlorpyrifos's inhibition of cholinesterase, the researchers added specific concentrations of pyrene, benzo(a)pyrene, fluoranthene, and anthracene to an incubation mixture containing chlorpyrifos and purified cholinesterase.

Eisenreich analyzed air and water sampled from a number of sites in eastern and central Lake Superior for 35 different PCBs and 14 PAHs, including the carcinogens benz[a]-anthracene, phenanthrene, pyrene, chrysene and benzo[a]pyrene.
Contract notice:Project management for the repair of the roofs of building 10 (workshops) at the Lyce Pyrene in Pamiers (operation no.
Bitumen fume and condensate contain a small fraction of polycyclic aromatic hydrocarbons (PAHs), including the known carcinogen benzo(a) pyrene (BaP).
METHODS: Larvae from the ER and a reference site on King's Creek (KC) were subjected to two 24-hr aqueous exposures of benzo[a] pyrene (BaP; 0-400 [micro]g/L).
Because PAH exposure occurs as a mixture of compounds, and because pyrene is almost always found in this mixture, pyrene and its metabolite 1-hydroxypyrene (1-OHP) are considered appropriate surrogate markers of total PAH exposure (Jacob and Seidel 2002).
Kagan's follow-up studies have examined seven more of the simples PAHs, including two of the most common -- fluoranthene and pyrene.
Among four-ring compounds, chrysene (9 [micro]M), which is enriched in highly weathered crude oil, was non-toxic, whereas pyrene (1-5 [micro]M), which is generally absent from weathered ANS crude oil, induced a syndrome with features similar to TCDD exposure that occurred between 80 and 96 hpf.
