The quantitative and rapid method for measuring the biodegradation of polymer materials in soil was developed. In this study, cellophane film was used as a model biodegradable polymer and the biodegradation was assayed by measuring the amount of glucose which was produced by a hydrolysis reaction using HCl after collecting the film from soil. Cellophane film was degraded 41.2% in 4 months during winter while it was degraded 76.5% in 2 months during summer. It means that biodegradation in soil is affected by environmental conditions. The biodegradation was also measured in an incubator (30
