Capillary Electrochromatography: Polycyclic Aromatic Hydrocarbons

Electrochromatography is utilized to separate a mixture of 16 different polycyclic aromatic hydrocarbons (PAHs). Fused-silica capillary columns ranging in size from 50 to 150 pm i.d. were packed (20-40-cm sections) with 3-pm octadecylsilica particles. A potential of 15-30 kV is applied across the 30-50-cm total length capillary column to generate electroosmotic flow that carries the PAHs throug...

Polycyclic aromatic hydrocarbons in carcinogenesis.

A symposium on "Polycyclic Aromatic Hydrocarbons (PAHs) in Carcinogenesis" was presented at the third International Congress of Pathophysiology held in Lathi, Finland, 28 June-3 July 1998. The congress was also sponsored by the International Union of Biological Sciences and the International Society of Free Radical Research. Institutional support for the symposium included the Electric Power Re...

Biodegradation of Polycyclic Aromatic Hydrocarbons (PAHs) in Petroleum Contaminated Soils

Polycyclic aromatic hydrocarbons are a class of potentially hazardous chemicals of environmental and health concern. PAHs are one of the most prevalent groups of contaminants found in soil. Biodegradation of complex hydrocarbon usually requires the cooperation of more than single specie. In this research biotreatment of PAH (phenanthrene) was studied in a solid-phase reactor using indigenou...

A periodic table for polycyclic aromatic hydrocarbons. Isomer enumeration of fused polycyclic aromatic hydrocarbons. Part I

a few people, however, who recognize a need to use the system but, for reasons of their own, choose to have a search intermediary do it for them or at least work with them on a graphical search session. At this point, therefore, it appears that the role of the search specialist has evolved away from searches originated by individual users (except in a few cases) who now can and should run their...
