ActivePlastics—Determination of the aerobic biodegradation of non-floating materials exposed to marine sediment—Method by analysis of evolved carbon dioxide
塑料 暴露于海洋沉积物中非漂浮材料最终需氧生物分解能力的测定 通过分析释放的二氧化碳的方法
Application Summary AI generated
This standard specifies a laboratory test method for measuring the aerobic biodegradation of non-floating plastic materials when exposed to marine sediment, by analyzing the carbon dioxide evolved. It is applied in environmental testing and material science to assess the biodegradability of plastics intended for use in marine environments, such as fishing gear, packaging, or agricultural films that may sink and settle on the seabed. The method provides a controlled simulation of seabed conditions to evaluate the ultimate biodegradation potential of these materials.
