Bioactivity profiling and categorization of petroleum substances in toxpi. point-of-departure values derived from sixteen distinct assays or assay parameters were integrated for quantitative bioactivity profiling of 21 petroleum substances in toxpi (a). the plot reflects a global ranking of petroleum substances according to their cumulative toxpi score, i.e. each data point represents the sum of individual assay scores shown in the respective bioactivity profiles. potential bioactivity-based correlations were analyzed using the hclust function in r (b). [vhgo = vacuum & hydrotreated gas oils; srgo = straight run gas oils; ogo = other gas oils; hfo = heavy fuel oils; rae = residual aromatic extracts]
