Notes: DNR-1 = (2,6 DMN + 2,7 DMN)/1,5 DMN. TMNR = (1,3,7 TMN)/(1,3,7 TMN + 1,2,5 TMN). MPI-1 = 1,5 (2MP + 3MP)/(P + 1MP + 9MP). MDR = 4MDBT/1MDBT. 4 MDBT = 4 methyl dibenzothiopene. 2,6/2,7 DMN = 2,6/2,7 dimethyl naphthalene. 1,5 DMN = 1,5 dimethyl naphthalene. 1,3,7 = 1,3,7 trimethyl naphthalene. 1/2/3/9 MP = 1/2/3/9 methyl phenanthrene.
