Abstract: A method for multi-residues detection of organochlorine, pyrethroid, and organophosphorus pesticide residues has been developed, in which a capillary gas cheomatography system with dual-injector, dual-column, single temperature-pro- grammed oven, and dual-detector was used to separate and assay the residues in Chinese tea samples. The analytical performance of this method shows preferential merits, such as precision, high standard spiked recovery and limits of determination.

Key words: organochlorine, pyrethroid, organophosphorus, pesticide residues, gas chromatography
