Benz[j]aceanthrylene is a member of phenanthrenes.

Benz[l]aceanthrylene is a member of phenanthrenes.

Benzo[a]fluoranthene is a member of anthracenes. Benzofluoranthene is one of over 100 different polycyclic aromatic hydrocarbons (PAHs). PAHs are chemicals that are formed during the incomplete burning organic substances, such as fossil fuels. They are usually found as a mixture containing two or more of these compounds. (L10)

Benzo[a]pyrene, also known as 3,4-Benzopyrene or 3,4-BP, is classified as a member of the Benzopyrenes. Benzopyrenes are organic compounds containing a benzene fused to a pyrene(benzo[def]phenanthrene) ring system. Benzo[a]pyrene is formally rated as a carcinogenic (IARC 1) potentially toxic compound. Benzo[a]pyrene is a crystalline, aromatic hydrocarbon consisting of five fused benzene rings and formed during the incomplete combustion of organic matter. Benzo[a]pyrene is primarily found in gasoline and diesel exhaust, cigarette smoke, coal tar and coal tar pitch, charcoal-broiled foods and certain other foods, amino acids, fatty acids and carbohydrate pyrolysis products, soot smoke, creosote oil, petroleum asphalt and shale oils. This substance is used only for research purposes. Benzo[a]pyrene is reasonably anticipated to be a human carcinogen (NCI05). Its diol epoxide metabolites (more commonly known as BPDE) react and bind to DNA, resulting in mutations and eventually cancer. It is listed as a Group 1 carcinogen by the IARC. In the 18th century a scrotal cancer of chimney sweepers, the chimney sweeps' carcinoma, was already connected to soot. [Wikipedia]

Benzo[j]fluoranthene appears as yellow crystals. Insoluble in water. Benzo[j]fluoranthene is a member of naphthalenes. Benzo[j]fluoranthene is a yellowish, aromatic hydrocarbon consisting of five fused rings and formed by the incomplete combustion of organic matter. Benzo(j)fluoranthene is primarily found in certain foods, cigarette smoke, gasoline exhaust, coal tar, coal smoke, oil heat emissions, crude oils and used motor oils. This substance is used only for research purposes. Benzo(j)fluoranthene is reasonably anticipated to be a human carcinogen. (NCI05) Benzo[j]fluoranthene can cause cancer according to an independent committee of scientific and health experts. Benzo[j]fluoranthene is one of over 100 different polycyclic aromatic hydrocarbons (PAHs). PAHs are chemicals that are formed during the incomplete burning organic substances, such as fossil fuels. They are usually found as a mixture containing two or more of these compounds. It is one ingredient of cigarette. (L10) See also: Tobacco Smoke (part of).

Benzo[k]fluoranthene appears as pale yellow needles or yellow crystalline solid. (NTP, 1992) Benzo[k]fluoranthene is a member of naphthalenes. Benzo[k]fluoranthene is a pale yellow aromatic hydrocarbon consisting of five fused rings and is produced by the incomplete combustion of organic matter. Benzo(k)fluoranthene is primarily found in gasoline exhaust, cigarette smoke, coal tar, coal and oil combustion emissions, lubricating oils, used motor oils and crude oils. This substance is used only for research purposes. Benzo(k)fluoranthene is reasonably anticipated to be a human carcinogen. (NCI05) Benzo[k]fluoranthene can cause cancer according to an independent committee of scientific and health experts. Benzo[k]fluoranthene is one of over 100 different polycyclic aromatic hydrocarbons (PAHs). PAHs are chemicals that are formed during the incomplete burning organic substances, such as fossil fuels. They are usually found as a mixture containing two or more of these compounds. It is one ingredient of cigarette.(L10)
