✦ Synopsis

In order to control the quality of trimethyl-lead determination in urban dust, the Standards, Measurements and Testing Programme (formerly BCR) of the European Commission organized interlaboratory studies of which the final aim was to certify a Reference Material. This paper describes the preparation of an urban dust reference material (CRM 605), the homogeneity and stability studies, and the analytical work performed for the certification of the trimethyl-lead content (7.9 AE 1.2 mg kg À1 by mass).
