유통 한약재의 내분비계장애물질 모니터링-유통한약재 중 잔류농약에 관한 조사연구

Abstract

Objectives: Research on pesticide residues as endocrine disruptors in herbal medicines was initiated by Korea Food & Drug Administration in 1999. The presence and levels of certain pesticides in selected herbal medicines samples were determined. Forty species of herbal medicies which have no background data on pesticide residues including Osterici Koreani Radix were collected this year. Methods: 276 samples out of total 427 were circulated in Korea, and the others were in China. In order to analyze many pesticides in large number of samples, simultaneous multi-residue analysis of pesticides by GC-ECD was used. The GC-MSD analysis was followed to confirm the identity of the detected pesticide in each sample. Results and conclusions: The frequencies of pesticide detection in natural medicines were 18 samples circulated in Korea and 12 samples circulated in China. The range of pesticide residues for DDT was 0.007~0.09ppm in 8 samples. That for lindane was 0.001~0.02ppm in 7 samples, for endosulfan was 0.001~0.074ppm in 6 samples, for methoxychlor was 0.004~0.161ppm in 5 samples, for chlordane was 0.006~0.02ppm in 4 samples. The range of pesticide residues for parathion was 0.001ppm in 1 samples.
