is a powerful carcinogen which accounts to about 20-40mg per cigarette.
The compounds mainly fall into the following 12 aromatic hydrocarbon series: naphthalene (m/z 128, m/z 142, m/z 156, m/z 170, m/z 184, m/z 198), phenanthrene (m/z 178, m/z 192, m/z 206, m/z 220), benzopyrene
(m/z 252), fluoranthene (m/z 202, m/z 216), dibenzothiophene (m/z 184, m/z 198, m/z 212, m/z 226), benzonaphthothiophene (m/z 234), dibenzofuran (m/z 168, m/z 182, m/z 196), fluorene (m/z 166, m/z 180, m/z 194), chrysene (m/z 228, m/z 242, m/z 256), biphenyl (m/z 154, m/z 168, m/z 182), triaromatic sterane (m/z 231) and benzohopane (m/z 191).
Products including anthracene, benzopyrene
(benzo(a) pyrene), bitumen, carbon black, Keure creosote, coal tar pitch, naphthalene, etc.
We have previously demonstrated that the traffic intensity was correlated with the content of the main pollutants (oxides of sulfur, nitrogen, carbon, benzine, kerosene, benzopyrene
and formaldehyde) in the air along highways in Russian (r = 0.
5, PM10, nitrogen dioxide, sulphur dioxide, ozone, carbon monoxide, lead and ammonia -- and four parameters with annual standards -- benzene, benzopyrene
, nickel and arsenic.
Antioxidant responses to benzopyrene
and Aroclor 1254 exposure in the green mussel, Perna viridis.
Furthermore, it is an active alkaloid modulate benzopyrene
metabolism through cytochrome P450 which is essential for metabolism and transport of xenobiotics and metabolites (Reen et al.
In answer to the question of the possible origin of the benzopyrene
detected in residences] Either way it is important, if it really originates from fuel burning, to make it clear that Vila Carioca, the area in the Ipiranga region, is a greatly industrialized area, where in reality the industrialization still often uses fuel burning to generate vapor and heat, in other words, boilers are used in most of the industries.
Radio Liberty reports that the Service has found no benzopyrene
in the Roshen confectionary products being sold in Armenia.
and salts of heavy metals were not found in confectionery of the Ukrainian Roshen company, the press service of Ministry of Health of Kyrgyzstan said with the reference to the Director General of the Department of Disease Prevention and State Sanitary and Epidemiological Control Tolo Isakov.
Cigarette smoke contains a large number of substances which are recognized as carcinogens and mutagens including radioactive polonium, cadmium, benzopyrene
, dimethylbenzanthracene, dimethylnitrosamine, naphthalene and methnaphthalene.
The results showed the levels of benzopyrene
, a known carcinogen found in the noodles, were less than 5 ppb (parts per billion)--far below the regulatory limit of 10 pbb, the DOH noted.
