PAH was measured by GC-MS and listed as blank corrected mean values (N = 2) with standard deviation in parenthesis. The PAH were extracted with cyclohexane from the two water suspensions of each particle used for the instillation in mice. ND = Not Detected
^aThe highest concentrations given in the Certificate of Analysis measured by several different methods and the associated expanded uncertainty given in parenthesis. ^£For NIST2975 the value is for Dibenz[a,h + a,c]anthracene
