The Salmonella mutagenicity assay and chemical analyses were used to evaluate the emissions from the open burning of scrap rubber tires that had been cut into either of two sizes, CHUNK or SHRED. The mutagenic potencies in strain TA98 of the dichloromethane-extractable particulate organics were generally greater than that of the semivolatiles. In addition, the open burning of CHUNK tires produced a higher burn rate and more potent organics in the presence of S9 than did SHRED tires. These results demonstrate for the first time that the open burning of scrap rubber tires produces a high mutagenic emission factor, posing potential environmental and health effects.
