  Acrolein - Wikipedia, the free encyclopedia
In organic chemistry, acrolein or propenal is the simplest unsaturated aldehyde.
Acrolein is such a severe pulmonary irritant and lacrimating agent that it has been used as a chemical weapon during World War I.
Acrolein is also a metabolite of the chemotherapy drug cyclophosphamide, and is associated with hemorrhagic cystitis.

 Acrolein (CASRN 107-02-8), IRIS, Environmental Protection Agency
The 1988 classification for acrolein was based on the increased incidence of adrenal cortical adenomas in female rats and carcinogenic potential of an acrolein metabolite, its mutagenicity in bacteria, and its structural relationship to probable or known human carcinogens.
Acrolein was too toxic to evaluate its tumor promoting potential, and the impact of its cytotoxicity on conclusions about its tumor initiating potential cannot be determined from this study alone.
(1985), acrolein administered by the inhalation route is retained primarily in the upper respiratory tract because of its reactivity.

 EPA - Air Toxics Website - Acrolein
Acrolein is primarily used as an intermediate in the manufacture of acrylic acid.
Acrolein is considered to have high acute toxicity, based on short-term animal tests in rats.
EPA has classified acrolein as a Group C, possible human carcinogen, based on limited evidence of carcinogenicity in animals, the structural similarity of acrolein to substances possibly carcinogenic to humans, the carcinogenic potential of one of its metabolites, and the lack of human data.

 Acrolein (EHC 127, 1991)   (Site not responding. Last check: 2007-10-24)
Acrolein is released into the atmosphere during the production of the compound itself and its derivatives, in industrial and non-industrial processes involving incomplete combustion and/or thermal degradation of organic substances, and, indirectly, by photochemical oxidation of hydrocarbons in the atmosphere.
When mixtures of acrolein or 1,3-butadiene with nitrogen monoxide and air were irradiated in a smog chamber, the time required for the half-conversion of 1,3-butadiene to acrolein was always shorter than that required for the half conversion of acrolein.
Acrolein was found to bind to microsomal protein in the absence of NADPH or in the presence of both NADPH and a mixed-function oxidase inhibitor.

Acrolein is removed from surface water primarily by reversible hydration, biodegradation by acclimatized microorganisms, and volatilization (Bowmer and Higgins, 1976; Tabak et al., 1981; Irwin, 1987; Haag et al., 1988b; Howard, 1989; ATSDR, 1990; Springborn Laboratories, 1993).
Acrolein was detected in the emissions from four varieties of heated cooking oils in China (Shields et al., 1995) at concentrations ranging from 49 µg/litre (peanut oil) to 392 µg/litre (rapeseed oil).
Acrolein is mutagenic in vitro, inducing gene mutations in both bacteria and mammalian cells in culture, as well as structural chromosomal aberrations in CHO cells and sister chromatid exchanges in CHO cells and cultured human lymphocytes.

Acrolein is a severe pulmonary irritant and powerful lachrymogen at a concn of 3 ppm (7 mg/cu m) and greatly irritates the conjunctiva and mucous membranes of upper resp tract.
Acrolein is metabolized in vitro by liver and lung microsomes to glycidaldehyde.
Acrolein, a genotoxic aldehyde released in the metabolic activation of the cytostatic drug cyclophosphamide, is inactivated by glutathione transferases either by conjugation with reduced glutathione or by covalent binding to the enzymes in the absence of glutathione or by covalent binding to the enzymes in the absence of glutathione.

 Edison's 1914 Anti-Cigarette Letter, in High School Education 1894 Context
Nowadays, compared to Edison and his era, education has been so dumbed down that high school graduates, college, and graduate school "graduates" do not know as much science on this subject, as did grade school children of the 1885-1914 era.
Wherefore, too many people nowadays do not, and CANNOT, understand Edison's letter referencing acrolein, and brain damage, and not hiring smokers, as reprinted above.
Solution: Let's require that to receive a high school diploma, would-be graduates must be able to understand and explain
