Separation of large polycyclic aromatic hydrocarbons in particulate matter by liquid chromatography. Jinno, K.; Miyashita, Yoshikatsu; Sasaki, Shinichi; Fetzer, John C.; Biggs, Wilton R. (Sch. Mater. Sci., Toyohashi Univ. Technol., Toyohashi 440, Japan). Environ. Monit. Assess., 19(1-3), 13-25 (English) 1991.In this article, certain chemicals are used. Some of their cas registry numbers are 196-42-9 and 6596-38-9 CODEN: EMASDH. ISSN: 0167-6369. DOCUMENT TYPE: Journal CA Section: 59 (Air Pollution and Industrial Hygiene) Section cross-reference(s): 80 Liq. chromatog. was coupled to a computerized photodiode array detector. The former sepd. the components in a diesel particulate matter ext. and the latter spectrally differentiated the large polycyclic arom. hydrocarbons (PAHs) 24 ring-carbons. Since each PAH has a characteristic UV/visible absorbance spectrum, each generated a unique pattern of absorbance max. and min. Computerized pattern recognition techniques were used to investigate quant. structure-activity relationships of the PAHs as predictors of carcinogenicity. The chem. profile of a series of unsubstituted PAHs, for which carcinogenic data was available, was represented by 17 descriptors of the reactivity and properties of those PAHs. Using this data set, the properties of another series of PAHs were found to be consistent with their reported carcinogenicity. .
