A simple gas chromatographic method has been developed to determine 2,4-and 2,6-diaminotoluenes in commercial polyurethane foams. 2,4-and 2,6-Diaminotoluene could be detected as heptafluorobutyryl derivatives by using an electron capture detector ; the lower limits of detection were 5 pg and 2 pg, respectively. It was found that 2.7-3.0 μg/g of 2,4-and 1.3-1.9 μg/g of 2,6-diaminotoluene were present in three commercial polyurethane foams. Mutagenicity test for 2,4-, 2,6-diaminotoluenes and toluene extracts of polyurethane foams was performed by the Ames method in Salmonella typhimurium TA 98 and TA 100. The toluene extract of polyurethane foam containing 3.08 μg of 2,4-and 1.90 μg of 2,6-diaminotoluene, was mutagenic in TA 98 (143 revertants/g polyurethane foam), whereas mutagenicity of pure 2,4-and 2,6-diaminotoluene was 1410 and 370 revertants per 100 μg, respectively.
