Interlaboratory evaluation of trace element determination in workplace air filter samples by inductively coupled plasma mass spectrometry
Autor: Michael J. Brisson, Stanley A. Shulman, Kevin Ashley, Alan M. Howe
Publikováno v: J. Environ. Monit.. 14:360-367
Inductively coupled plasma mass spectrometry (ICP-MS) is becoming more widely used for trace elemental analysis in the occupational hygiene field, and consequently new ICP-MS international standard procedures have been promulgated by ASTM Internation

Evaluation of Sampling Methods for Measuring Exposure to Volatile Inorganic Acids in Workplace Air. Part 1: Sampling Hydrochloric Acid (HCl) and Nitric Acid (HNO3) from a Test Gas Atmosphere
Autor: Davy Rousset, Andreas Moritz, Darren Musgrove, Dietmar Breuer, Krista Gusbeth, Martine Demange, Alan M. Howe, Véronique Oury, Michel Dorotte
Publikováno v: Journal of Occupational and Environmental Hygiene. 8:492-502
Historically, workplace exposure to the volatile inorganic acids hydrochloric acid (HCl) and nitric acid (HNO3) has been determined mostly by collection on silica gel sorbent tubes and analysis of the corresponding anions by ion chromatography (IC).

Performance of methods for measurement of exposure to inorganic acids in workplace air
Autor: Alan M. Howe, Dietmar Breuer
Publikováno v: J. Environ. Monit.. 8:120-126
BGIA has organised round robins for the analysis of samples of inorganic acids in workplace air for a number of years. Test samples of the volatile acids HCl and HNO(3) are collected from a standard atmosphere and samples of the non-volatile acids H(

Development of an international standard for the determination of metals and metalloids in workplace air using ICP-AES: evaluation of sample dissolution procedures through an interlaboratory trial
Autor: Owen Butler, Alan M. Howe
Publikováno v: Journal of Environmental Monitoring. 1:23-32
Inductively coupled plasma atomic emission spectrometry (ICP-AES) is rapidly overtaking atomic absorption spectrometry (AAS) as the method of choice for the determination of toxic metals in workplace air. However, the few ICP-AES methods that have be

Sampling and analysis considerations for the determination of hexavalent chromium in workplace air
Autor: Kevin, Ashley, Alan M, Howe, Martine, Demange, Olle, Nygren
Publikováno v: Journal of environmental monitoring : JEM. 5(5)
Airborne hexavalent chromium (Cr[VI]) is a known human respiratory carcinogen and allergen. Workers in a variety of industries may be exposed to airborne hexavalent chromium, with exposures frequently occurring via inhalation and/or dermal contact. A
