Analytical methodology for bioactive compounds. Photochemically assisted analysis of chlorinated hydrocarbon pesticides in the presence of polychlorinated biphenyls

Determination of (Z)-9-tetradecen-1-ol formate, a Heliothis species mating disruptant, in air by electron-capture gas chromatography following photolytic cleanup

“…The key to the general utility of the method is the use of ultraviolet (UV) irradiation as a clean-up technique. The UV irradiation of either solutions or solids has been reported for both identification of pesticides (Banks and Bills, 1968;Glotfelty, 1972) and for extract cleanup (Caro, 1971;Leavitt et al, 1973).…”

Gas chromatographic determination of several cyclodiene insecticides in the presence of polychlorinated biphenyls by photoisomerization reactions

“…Several methods have been developed for the elimination of PCB interferences in the determination of organochlorine pesticides in environmental samples. (Leavitt et al, 1973; Lewis et al, 1976). However, these procedures are not suitable for the determination of cyclodiene insecticides.…”

Photochemical confirmation of mirex in the presence of polychlorinated biphenyls

“…Chlorinated biphenyls have relatively poor stabilities to ultraviolet light. This property has been utilized by Leavitt et al (1973) for the degradation of PCB's in the analysis of , '-DDT, , '-DDE, and dieldrin. Under the conditions employed by these authors, long exposure times were necessary and there was considerable photodegradation of the pesticides.…”
