Polycyclic Aromatic Hydrocarbons (PAHs)

Applications 4,5-Methanochrysene shows moderate degree of carcinogenic activity. As a polycyclic aromatic hydrocarbon (PAH), it is considered as a pollutant.

Applications 5-Methylbenz[a]anthracene is a monomethylated polycyclic aromatic hydrocarbon with carcinogenic activity. Not a dangerous good if item is equal to or less than 1g/ml and there is less than 100g/ml in the package References Majumdar, R. et al.: Mutat. Res. Lett., 175, 1 (1986); Smith, I.A. et al.: Int. J.

Applications 1-Hydroxypyrene-d9 is found in humane urine after exposure to coal tar and a coal derived product. References Jongeneelen, F.J., et al.: Int. Arch. Occup. Environ. Health, 57, 47 (1985)

Applications Polycyclic aromatic hydrocarbons (PAHs) and their PAH-DNA adducts in lung tissues, and their ability to mutate the Ki-ras oncogene in PAH-induced tumors. Seven PAHs were studied: cyclopenta[cd]pyrene (CPP), benzo[a]pyrene (B[a]P), benzo[b]fluoranthene (B[b]F), dibenz[a,h]anthracene (DBA), 5-methylchrysene (5MC), benz[j]aceanthrylene (B[j]A), and dibenzo[a,l]pyrene (DB[a,l]P).
