Samples of virgin suspension PVC resin from eleven major production si
tes in Europe have been analysed by HRGC/HRMS for PCDDs and PCDFs usin
g a dissolution method. The method has been validated in two laborator
ies, down to levels of detection of less than 1 ppt. The results show
that there are no PCDDs and PCDFs in virgin PVC resin above the levels
of quantitiation. (C) 1997 Elsevier Science Ltd.
