A collection of GC/MS data obtained during the analysis of 1,159 household products for six common chlorocarbon solvents has been reanalyzed for the presence and concentration of 25 additional chemicals. Using computerized GC/MS software, 1,043 of the original GC/MS data files were recovered and analyzed for the presence of the additional chemicals. An efficient microcomputer-based data base system was developed and used to assemble, reduce, and view the analytical data. Of the 25 additional chemicals, those found most frequently in the household products include acetone, 2-butanone, methyicyclohexane, toluene, ethylbenzene, m-xylene, and o, p-xylene. A total of 63.6% of the products analyzed in this study contained on or more of the 25 additional analytes at concentrations greater than or equal to 0.1% by weight. Five analytes, 1,1,2,2-tetrachloroethane, chlorobenzene, styrene, nonane, and d-limonene, were not found in any of the products in concentrations greater than or equal to 0.1% by weight. The major accomplishment of this work is the completion of a large data base of semiquantitative information for 31 chemicals in the home environment. The quantitative information presented in the report is available on diskette in a spreadsheet format. |
