Which substance is used in NIOSH Method 7082 for air sampling?

Glass fiber filters
Mixed cellulose ester filters
Polyester filters
Activated charcoal filters

The correct answer is: Mixed cellulose ester filters

NIOSH Method 7082 is specifically utilized for the determination of airborne lead and other metals via the collection of particulate samples. This method employs mixed cellulose ester filters due to their unique properties that effectively capture particulate matter while allowing for efficient analysis. These filters provide a good balance between retention and flow rate, making them suitable for sampling fine particles in air. Mixed cellulose ester filters have the ability to effectively retain lead particles while minimizing the adsorption of gases, which is crucial for the accuracy of this method. Their composition helps in achieving reliable results when analyzing samples for lead and other trace metals. This selection of filter type is key to ensuring the integrity and validity of the sampling process as per the standardized method laid out by NIOSH.
