Abstract

A new environmental certified reference material (CRM) for the determination of multielements in aerosol particulate matter has been developed and certified by the National Institute for Environmental Studies (NIES), Japan, based on analyses by a network of laboratories using a wide range of methods. The origin of the material was atmospheric particulate matter collected on filters in a central ventilating system in a building in Beijing city centre. The homogeneity and stability of this material were sufficient for its use as a reference material. Values for elemental mass fractions in the material were statistically determined based on the analytical results of the participating laboratories. Eighteen certified values and 14 reference values were obtained. The diameters, obtained from a micrographic image using image analysis software, of 99% of the particles were less than 10 μm, demonstrating that almost all the particles in the material could be classified as particles of 10 μm or less in aerodynamic diameter. The chemical composition and particle size distribution of this material were close to those of an authentic aerosol collected in Beijing. NIES CRM 28 is appropriate for use in analytical quality control and in the evaluation of methods used in the analysis of aerosols, particularly those collected in urban environments in northeast Asia
