Man-made textile fibers are frequently encountered as trace
evidence in criminal investigations. This study examined the
effects of burial in soil on the biodeterioration of synthetic
textile fibers such as cellulose acetate, nylon, polyesters and
acrylics. Cellulose acetate fibers began to show signs of
decomposition within two months after burial in common garden
topsoil and were completely degraded within four to nine months. It
was found that severely decomposed cellulose acetate fibers could
be identified by pyrolysis-gas liquid chromatography even when
other methods such as polarized light microscopy and dispersion
staining failed. The solubility behavior of the cellulose acetate
fibers also was altered. The other types of fibers showed no
detectable alteration at the end of the twelve-month study.
