Samples were analyzed via the Countrywide Institute for Occupational Security and Wellness (NIOSH) contract laboratory in accordance with the NIOSH Guide of Analytical Methods (NMAM) 2016 process(thirteen) for your active samples and also the OSHA 1007 technique(twelve) with the passive samples. The mass concentrations of passive badges have been then calculated While using the manufacturer’s up-to-date uptake charge of sixteen.
