Determination of pyrethroid multi-residues in vegetables by high-performance liquid chromatography

Simultaneous determination of five pyrethroid residues in vegetables including fenpropathrin,lambda-cyhalothrin,deltamethrin,fenvalerate and permethrin were performed by high performance liquid chromatography with florisil solid-phase extraction.Four kind samples with five pyrethroids were well detected under the optimized conditions.The recoveries for cabbage,cauliflower,carrot,and green pepper were 80.7%～106.2%,80.5%～102.0%,63.9%～109.3%,74.9%～109.0%,respectively.Their relative standard deviation(n=5) were less than 14.5%.
