• Description:
  Background: Occupational exposure limits are generally decreasing. It is important to have sampling methods that can quantify concentrationsbelow the exposure limit. Studies report that many US hygienists do not sample for inhalable mass concentrations, e.g., the IOM, possibly because of the ease of use, low cost, and disposability of the 37-mm cassette. Objectives: 1. To compare the prototype sampler to the IOM sampler for metal working processes. 2. Determine whether the new sampler improves the LOD for metals. Methods: Sampler Assemblies Prototype a. 37-mm 8.0 um MCE filter with bonded capsule b. Housing c. Pump: d. SensidyneR Gilian12 e. 8 Lpm IOM a.. 25-mm 0.8 um MCE filter b. Housing c. Pumps: d. SKC Universal PCRX4 e. GilianR GilAirPlus f. 2 Lpm Sampling a. Sampled May 17 - December 8, 2016 b. Collected paired prototype and IOM personaland area samples c. Analyzed using modified NMAM Method 7300 (ALS, UT) - 15 metals Evaluation criteria Kruskal-Wallis (P>0.05) for differences between sampler by: a. All metals collected b. Prototype/IOM ratio for metals c. Prototype/IOM ratio for particle "size" Regression (Prototype vs IOM) by: a. All samples b.Personal vs area samples c. Particle "size". Results: 28 paired samples collected Mean sample duration = 7 hr Metals detected on: a. 21 / 28 samples b. 7/ 8 personal c. 14 / 20 area. Kruskal-Wallis a. Aggregate metal concentration: p = 0.66 b. P/I ratio between metals: p = 0.05 c. P/I ratio between particle "size": p = 0.40 Regression between paired samples. Conclusions: Prototype and IOM samplers were not significantly different. Only 11 metals were detected on prototype but not the IOM. Hence, LOD improvement was not assessed. [Description provided by NIOSH]
