摘      要：This European Standard specifies a method for sampling of Pb, Cd, As and Ni as part of the PM10 aerosol,microwave digestion of the samples and analysis by graphite furnace atomic absorption spectrometry or byinductively coupled plasma (quadrupole) mass *** European Standard is applicable for the measurement of Pb, Cd, As and Ni as part of the PM10 aerosolfraction in the concentration ranges listed in Table 1. Table I -- Working ranges of the method in ng/m3The actual lower limits of the working ranges depend upon the variability of the laboratory filter blank (5.3.1). Thelower limits of the working ranges given in Table 1 are expected values based upon performance achieved in thefield validation tests. Similarly the upper limits of the working ranges have been set arbitrarily based upon themaximum daily values measured during the field validation tests. The method can be applied to higherconcentrations provided the PM10 collection characteristics of the sampler are not compromised.
