Separation and Characterization of Polynuclear Aromatic Hydrocarbons in Urban Air-Borne Particulates

Diesel Exhaust CompositionandOdorStudies

“…This technique is similar to that reported by Sawicki 28 and co-workers. The details of our methods and analytical data on the composition of the particulate will be published later when this phase of the work is completed.…”

Transformation of rat and mouse embryo cells by a new class of carcinogenic compounds isolated from particles in city air

“…A determination (Sawicki et al, 1960) of twelve polynuclear aromatic hydrocarbons in these secondary benzene-solubles by chromatography and UV spectroscopy showed them to amount to between 3 and 7 % of those found in the original benzene extract. Benzo(a)pyrene in the methanol extract, for example, came to 3.3 % of the amount in the benzene extract.…”

Polynuclear Aromatic Hydrocarbons Associated with Particulates in Pittsburgh Air

“…1 -2 The analytical technique consists of column chromatographic separation followed by ultraviolet-visible spectral investigation of the many fractions, 3 procedures which usually require two days of laboratory work for completion of an analysis. The procedures are tedious, time-consuming, and serve to monopolize the time of limited numbers of laboratory personnel.…”
