The results of a study to determine the biological stability of clear, colorless, biocide-treated PVC film are presented. With the exception of a resistant control, all the PVC film samples tested contained a plasticizer susceptible to biological deterioration. Biocide-treated and control PVC film samples were subjected to biological attack in soil burial. Portions of each sample were exposed to leaching and to weathering in a weatherometer followed by soil burial to test the stability of each biocide to loss by water and weathering exposure. Of the 32 biocide preparations tested only 2, N-(trichloromethylthio) phthalimide and copper 8-quinolinolate, a known effective reference compound, were found to provide good protection for treated film in direct soil burial and in soil burial following leaching and weatherometer exposure. Natural weathering outdoors confirmed the results found with weatherometer exposed samples. The N-(trichloromethylthio) phthalimide was less effective than the reference compound in suppressing surface growth. In addition, N-(trichloromethylthio) phthalimide may not be compatible with all PVC formulations.
