Abstract: Abstract: A head-space method for the deteminatiou ofbenzene, toluene. ethy1 benzene and dimethy1 benzene inwater, urine or blood using a GC with a FID was devel oped. Internal standard were Tertiary Buty1 Alcohol.Glass cotumn packed with 80-120 mesh carbopack / 5% carbowax 20M. The detection limit was 0.1-0.05μg/ml.This method is sensitive, simple and rapid. it is useful in analitical toxicology.
