塑料生物降解性的试验评价方法

Test Evaluating Methods of the Biodegradability of Degradable Plastics

本文综述了目前国内外常见的几种可降解塑料生物降解性的试验评价方法，特别讨论了它们的优缺点。这些方法有土理法、皮特里培养皿法、酶分析法、放射性同位素示踪法以及生物体内试验法等。

In this Paper, several domestic and international commonly used methods for test evaluating the biodegradability of degradable Plastics are reviewed. Parhcularly,their advantagesand disadvantagrs are diseussed. These methods involve soil burial methed, Petri dishmethod,enzyme assay methed、radiolabelled method and test method in organisms etc..
