Standard Test Method for Collection and Analysis of Hexavalent Chromium in Ambient Atmospheres (Withdrawn 2014)


1.1 This test method covers the collection and measurement of hexavalent chromium [Cr(VI)] in the ambient atmosphere.

1.2 This test method collects and stabilizes atmospheric hexavalent chromium using an alkaline impinger buffer solution in a wet impingement sampling technique. Lead chromate [PbCrO4], generally considered poorly soluble in water, is soluble in the impinger solution up to 940 μg/L as hexavalent chromium.

1.3 This test method measures hexavalent chromium using an ion chromatographic separation combined with a post separation reaction with a colorimetric reagent and photometric detection.

1.4 This test method is applicable in the range from 0.2 to 100 ng/m3 of hexavalent chromium in the atmosphere assuming 20 m3 of air sample. The range can be extended upwards by appropriate dilution.

1.5 The values stated in SI units are to be regarded as the standard. The inch-pound units given in parentheses are for information only.

1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
