Development of pork fat reference material for OCPs BCR-CRM 430 : Part I, Preparation, homogeneity and stability
article
A pork fat sample was prepared and tested as candidate reference material for 10 organochlorine pesticides and metabolites (OCPs): hexachlorobenzene, α-, β- and γ-HCH, β-heptachlor epoxide, dieldrin, endrin, p,p'-DDT, p,p'-TDE and p,p'-DDE. Preparation and testing for homogeneity and stability of the OCPs in the pork fat are discussed. The coefficient of variation of pesticide determinations carried out to test the between-ampoule homogeneity ranged from 2.4-5.8% and was found to be very similar to that for the analytical method (2.5-4.9%). This means that the homogeneity is very good. Stability data over 12 months do not show any trends that suggest lack of stability. © 1992 Springer-Verlag.
