Organic combustion

Organic combustible substances subject to microbial tliermogenesis (e.g.. Agricultural products such as liay and grain)... 

Similar results were obtained with dibromoethene and dichloroethene. The considerable variation in conversion observed among the samples is believed to be due primarily to differences in the oxygen partial pressure in the tests. The oxygen partial pressure differences were a function of the amount of oxygen added to allow complete combustion of the organics and the actual amount of organic combusted. 

Sources. Benz[ ]anthracene is a major component of the total content of polynuclear aromatic hydrocarbons, also known as polycyclic aromatic hydrocarbons human exposure occurs primarily through smoking of tobacco, inhalation of products of incomplete organic combustion such as automobile exhaust, and ingestion of food contaminated by combustion effluents such as those that are smoked or barbecued. 

Just as with organic combustion aerosols, the chemical and physical nature of inorganic solid substrates can have a dramatic impact on the photoreactivity of adsorbed PAH. In 1980, Korfmacher and co-workers reported that BaP, pyrene, and anthracene all pho-tolyzed efficiently in liquid solution but were resistant to photodegradation when adsorbed on coal fly ash. Subsequent studies confirmed this observation and revealed that the carbon content of the ash (and the associated darkening of color) is a key factor in establishing the photostability of these PAHs. Indeed, they were stabilized at relatively small percentages of carbon, e.g., 5% or less (Behymer and Hites, 1985, 1988 Yokley et al., 1986 Dunstan et al., 1989 Miller et al., 1990).

The statement of Boyle that only a very small proportion of the bulk of the air is consumed, is easily explained by the fact that he has used alcohol or other organic combustibles, so that the volume of oxygen consumed has been replaced largely by the carbon dioxide and monoxide produced, and that only that variable volume has disappeared produced by the oxidation of the hydrogen of the combustible. It will be noted that Boyle, in using the term volatile nitre, recognizes like Hooke and Willis the similarity of the action of saltpeter to the unknown substance in the air. 

Almatrity (Almatrits). A series of commercial expls developed in 1925 at the Univ of Moscow, They consisted of chlorates and perchlorates together with organic combustible materials. They were claimed to be as stable and less sensitive to friction than Cheddites (see Vol 2,C155-L toCl64-R)...

Quantitative Determination.— The quantitative determination, of the amount of each element present in an organic compound, is ordinarily termed organic combustion as combustion or oxidation takes place in all of the determinations.

Identification of chemical tracers for the wide variety of organic combustion and secondary aerosol sources, which can be used to identify and quantify source contributions to ambient aerosol. For the health effects community, it would especially valuable to have simple indicators of sources, which need not be highly accurate but can be easily measured and used to correlate source contributions with health criteria.
