Description

The effectiveness of solid-phase extraction with Florisil for the determination of 12 organochlorine pesticide residues from human serum was examined. Recoveries greater than 84% and coefficients of variation better than 19% were obtained. Others methods, such as column partition and matrix solid-phase dispersion, were compared. The better method provides quantification limits ranging from 1.08 [mu]g/l for [gamma]-HCH and 37.5 [mu]g/l for p,p'-DDT when capillary gas-liquid chromatography with electron-capture detection is used for the final determination. http://www.sciencedirect.com/science/article/B6TG9-3TWXX3J-J/1/b7804f2ca479d02daf6147329c4f29c3
