DIN EN 14902-2005 环境空气质量.悬浮颗粒物质的PM10部分中Pb、Cd、As和Ni的标准测量方法
Ambient air quality - Standard method for the measurement of Pb, Cd, As and Ni in the PM10 fraction of suspended particulate matter; English version of DIN EN 14902
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 by
inductively coupled plasma (quadrupole) mass spectrometry.
This European Standard is applicable for the measurement of Pb, Cd, As and Ni as part of the PM10 aerosol
fraction in the concentration ranges listed in Table 1.
Table I -- Working ranges of the method in ng/m3
The actual lower limits of the working ranges depend upon the variability of the laboratory filter blank (5.3.1). The
lower limits of the working ranges given in Table 1 are expected values based upon performance achieved in the
field validation tests. Similarly the upper limits of the working ranges have been set arbitrarily based upon the
maximum daily values measured during the field validation tests. The method can be applied to higher
concentrations provided the PM10 collection characteristics of the sampler are not compromised.
