Silica Research Released - June 2021

In response to multiple requests for information related to the analysis of silica at lower levels (less than 0.05 mg/filter), AIHA PAT Programs has released research based on participant data from IHPAT round 212-224.
The Industrial Hygiene Proficiency Analytical Testing Program (IHPAT) for silica has been administered since 1974 and prior proficiency testing data evaluations were conducted in 1999 and 2014. This research seeks to provide an update to this valuable work.
