Determination of carbofuran and its metabolites. 1983

T D Spittler, and R A Marafioti

High-performance liquid chromatographic (HPLC) methods for the determination of carbofuran and its metabolites are described. Results obtained for carrot samples by HPLC are compared with those obtained using gas chromatography and nitrogen-specific detection for carbofuran and 3-hydroxy carbofuran and gas chromatography-mass spectrometry with selected ion monitoring for the determination of the three 7-phenol metabolites. The effect upon observed residue levels of conjugate formation by the 3-hydroxy and/or the 7-phenoxy groups of the four metabolites is demonstrated, and appropriate acid hydrolysis techniques are described. Variations in the HPLC parameters for different commodities are presented.

D010636 Phenols Benzene derivatives that include one or more hydroxyl groups attached to the ring structure.
D010945 Plants, Edible An organism of the vegetable kingdom suitable by nature for use as a food, especially by human beings. Not all parts of any given plant are edible but all parts of edible plants have been known to figure as raw or cooked food: leaves, roots, tubers, stems, seeds, buds, fruits, and flowers. The most commonly edible parts of plants are FRUIT, usually sweet, fleshy, and succulent. Most edible plants are commonly cultivated for their nutritional value and are referred to as VEGETABLES.
