Includes bibliographical references. "The pattern of organic contaminants leached from whole and shredded used has been compared by GC/FTIR, GC/MSD, UV/VIS-PDA spectrometry and by TLC after polarity fractionation by solvent extraction. The comparison shows the leached from both matrices are similar and that the extracted material does exhibit positive results in the Microtox test. Shredded tire material, however, shows very high concentrations of zinc, iron and manganese. This may complicate determination of the effects of leachable toxic organic contaminants. The results show as well that the amounts of extractable material recovered in both test methods are comparable but that for a comprehensive chemical examination, scale-up of the "standard" test methods is required. Organic contaminants identified and/or characterized in the tire leachate extracts by GC/FTIR are reported"--Abstract. Includes abstract in French. gccst Water pollution Canada. Environment Canada.
