  1. Elemental concentrations are shown in units of μg/g particle (ND = not detectable). Blank concentrations were subtracted. NIST2975 and CB were analyzed in duplicates (separated by slash). aReference values from Ball et al. (2000) [30] (the study only analyzed Co, Cu, Fe, Ni, V, and Zn). Note that we extracted for significantly longer time (several days vs. overnight) and with 25% nitric acid instead of 0.1 M phosphate buffer. bReference values from the MAK-Collection for Occupational Health and Safety (written communication of unpublished data of Degussa) [31]
