Note. The elemental composition of the SWA dusts was determined as described in Methods. For the SWA dusts, values in parentheses are estimates lying between the limit of detection (LOD) and limit of quantitation (LOQ). ND indicates not detected. The composition of the NIST material was determined by NIST. Empty cells indicate that an assay was not done.
