Hj. Abraham et al., INTERLABORATORY TEST FOR EXTERNAL QUALITY -CONTROL .3. DETERMINATION OF POLYCYCLIC AROMATIC-COMPOUNDS IN PARTICULATE MATTER, Staub, Reihhaltung der Luft, 53(7-8), 1993, pp. 311-318
Interlaboratory tests were organized by the Berliner Senatsverwaltung
fur Stadtentwicklung und Umweltschutz in autumn 1991 for external qual
ity control in the field of particulate matter analysis. In parallel w
ith the interlaboratory test for the determination of metals in partic
ulate matter described previously the determination of polycyclic arom
atic hydrocarbons was also done. The results obtained in a preliminary
and compulsary test were not at all satisfying evidencing the problem
s associated with analysis and insufficient competence of laboratories
.
