Area-level total airborne oxidants by exposure category

Exposure category (sample n)MedianRange
Referent vs exposed workers
 Referent workplaces (n=13)85.368.1–92.4
 Total exposed workplaces (n=22)270.3138.3–510.0
Across exposure subcategories
 Melting/alloying areas (n=10)271.3210.7–310.7
 Fabricating areas (n=7)150.0138.3–175.3
 Buffing/polishing areas (n=5)450.0420.0–510.0
  • All units are expressed in parts per million total oxidants in that area. Each measure represents the average value of at least four measurements made (see Methods section).
