What analytical method is used for lead wipe sampling?

The analytical method used for lead wipe sampling is NIOSH 9100. This method is specifically designed to quantify lead concentrations on surfaces, providing accurate measurements critical for assessing exposure in occupational settings.

NIOSH 9100 utilizes atomic absorption spectrometry or inductively coupled plasma mass spectrometry, which allows for sensitive detection of lead particles collected on wipes. This is particularly important in environments such as construction or manufacturing where lead is used or may be present, enabling employers to implement necessary safety measures to minimize exposure risks.

Other methods mentioned, like EPA 5040 or NIOSH 9000, are not specifically targeted for lead wipe sampling. They may pertain to different substances or types of analysis not focused on direct surface wipe sampling for lead. OSHA 1910.1025 pertains to lead standards in the workplace, but it does not define a specific method for wipe sampling analysis. Thus, NIOSH 9100 is the most appropriate and relevant choice in the context of lead wipe sampling.
