Fume condensates used in the study were generated, collected
and characterized by the Heritage Research Group, Indianapolis,
IN, as previously described (Kriech et al., 2007). A single paving,
roofing and lab generated roofing fume condensate were selected
for the two year dermal carcinogenicity bioassay from the four
samples of each asphalt type that were studied (identified in the
Kriech paper as samples TP-D, TR-A, and LR-A). They are referred
to as the ‘‘field-matched’’ paving or BURA fume condensate and
the ‘‘lab-generated’’ BURA fume condensate.
