| Abstract: | Objective To develop a method for quick analysis of pyrethroid pesticides in human blood by QuECHERS(Quick,Easy,Cheap,Effective,Rugged,Safe)-GC/MS.Methods With C18 and PSA as the absorbents,QuECHERS-GC/MS was conducted to determine the seven pyrethroid pesticides:bifenthrin,fenpropathrin,lambda-cyhalothrin,cyhalothrin,cypermethrin,fenvalerate and deltamethrin in human blood.Results For the seven pyrethroid pesticides tested,their linear range was of 1.0~10.0μg/mL,with RSD being among 5.6~10.3%,recovery range spanning across 79.6~108.6%,and the lowest detecting limits among 0.1~0.3μg/mL.Conclusion This method is simple,sensitive and accurate,capable of being used for rapid detection of pyrethroid pesticide in casework. |
