Scope: 1 This International Standard specifies flame and electrothermal atomic absorption spectrometric methods for the determination of the time-weighted average mass concentration of particulate lead and lead compounds in workplace air. 2 The method is applicable to personal sampling of the inhalable fraction of airborne particles, as defined in ISO 7708, and to static (area) sampling. 3 The sample dissolution procedure specifies hot plate or microwave digestion, or ultrasonic extraction (11.2). The use of an alternative, more vigorous dissolution procedure is necessary when it is desired to extract lead from compounds present in the test atmosphere that are insoluble using the dissolution procedures described herein. 4 The flame atomic absorption method is applicable to the determination of masses of approximately 1 μg to 200 μg of lead per sample, without dilution [1]. The electrothermal atomic absorption method is applicable to the determination of masses of approximately 0,01 μg to 0,5 μg of lead per sample, without dilution [1]. 5 The ultrasonic extraction procedure has been validated for the determination of masses of approximately 20 μg to 100 μg of lead per sample, for laboratory-generated lead fume air filter samples [2]. 6 The concentration range for lead in air for which this procedure is applicable is determined in part by the sampling procedure selected by the user (see 10.1).
