Laboratory studies <br />reported in 1992 showed that a naphthenic AC-20 asphalt was not <br />mutagenic (Modified Ames Assay using a solvent extract nor <br />cart no enic (mouse skin painting assay using a miners oil <br />diluent . IARC also concluded that mouse skin painting studies <br />showed that extracts of asphalts caused skin tumors; IARC would <br />therefore classify a solvent extract of asphalt as a ze carcinogen <br />(sufficient evidence in animal studies). However, these extracts <br />were derived by using benzene or toluene as the solvent and the <br />resulting extract does not realistically characterize asphalt to <br />which humans are exposed. The same criticism applies to recent <br />studies where roofing asphalt fume condensate or steam-refined <br />asphalt caused skin cancer in similar mouse painting studies, <br />This animal data should be interpreted cautiously since the health <br />effects may be dependent on variables such as solvent <br />extractionlsolvent dilution, source of crude oil, manufacturing <br />process and that these studies involved repeated exposure of <br />shaved skin which was never washed free of test material. <br />ECOLOGICAL INFORMATION <br />N Ecotoxieologgical Inlornation <br />'riot Mix As halt and asphalt materials are basically inert <br />materials which are not soluble or harmful in water environments. <br />Even the Environmental Protection A encyy's (EPA) Toxicity <br />Characteristic Leaching Procedures ~TLCP) test, their most extreme <br />and rigorous test for determining the toxicity of a substance, <br />perrormed on core and ground-up asphalt pavement materials, failed <br />to show any appreciable quantities of toxic materials leach from <br />asphalt pavement material. In 1992, the Illinois legislature <br />passed a bill (HN4038) stating that asphalt was a benign material <br />after extensive testing by the Illinois EPA and the Illinois <br />Department of Transportation. <br />iContlnued) <br />ASP0001o Paga6 <br />
