Us. Gill et al., TOXAPHENE (POLYCHLORINATED CAMPHENES) ANALYSIS IN HUMAN BLOOD, International journal of environmental analytical chemistry, 60(2-4), 1995, pp. 153-161
A method for the determination of toxaphene in whole blood using gas c
hromatography (GC)-electron capture negative ion ECNI/MS and pure poly
chlorobornane congerners has been evaluated. Blood samples were extrac
ted with hexane/acetone (9:1), extracts defatted with sulfuric acid, a
nalytes fractionated on Carbopack-C/Florisil (or silica gel) SPE colum
ns then concentrated to final volumes for GC-ECNI/MS analysis. For con
firmation, interference from PCBs and other organochlorine pesticides
were removed by nitration.
