“…Its radio purity was at least 99% after cleanup and isolation by thin-layer chromatography (TLC). In addition, five potential metabolites were prepared from [nng-14C]parathion: [14C]paraoxon was prepared as described by Fuhremann and Lichtenstein (1972) with nascent hydrogen produced from HC1 and zinc, and p-[14C]nitrophenol and p-[14C]aminophenol were prepared from [14C]parathion and [14C]aminoparathion, respectively, by hydrolysis in 1 N NaOH at 90 °C for 30 min, subsequent acidification and extraction with diethyl ether. Isolation and purification by TLC was conducted as described by Fuhremann and Lichtenstein (1972).…”

“…[14C]Parathion (97% radiopurity) labeled in the 2,6-phenyl positions (ICN Corporation, Irvine, Calif.) was diluted with nonradioactive parathion to a specific activity of 1.44 mCi/mmol. [14C]Paraoxon was prepared by oxidation of [14C]parathion with bromine as previously described (Fuhremann and Lichtenstein, 1972). Myristicin (98%) was isolated from nutmeg spice powder as previously described (Fuhremann et al, 1978) and d-carvone (96%) was purchased from Aldrich Chemical Co., Milwaukee, Wis.…”

“…Lichtensteinetal. (1969demonstrated synergistic effects of PCBs on DDT and Dieldrin in insects, and Fuhremann & Lichtenstein (1972) showed that PCBs increased in particular the toxicity of the oxygen analogues of organophosphorus insecticides to house-flies.…”
