The first worldwide interlaboratory assesment on persistent organic pollutants (POPs) under the Stockholm Convention was organized in the Asian/Pacific, Latin American and African regions during 2009–11.A relatively large number of laboratories reported data for the PCDDs/PCDFs and dioxin-like PCBs, especially in the Asian region. Within the Asian region, several participants used high-resolution GC/high-resolution MS systems optimized for dioxin analysis. The availibility of High-resolution mass spectrometer instrumentation is limited in the Latin America and African regions, although recently several new laboratories for dioxins have started in the Latin American region.
► The first assessment of the quality of dioxin analysis in developing countries. ► A critical evaluation of the statistical methods used to validate QA/QC data. ► A comparison of the analytical variation with the international literature. ► The first assessment of regional quality in both developed and developing regions.
