ActivePlastics—Determination of aerobic biodegradation of non-floating plastic materials in a seawater/ sandy sediment interface—Method by measuring the oxygen demand in closed respirometer
塑料 海水沙质沉积物界面非漂浮塑料材料最终需氧生物分解能力的测定 通过测定密闭呼吸计内耗氧量的方法
Application Summary AI generated
This standard specifies a test method for determining the aerobic biodegradation of non-floating plastic materials under conditions simulating the seawater/sandy sediment interface. It is applied in marine environmental testing, specifically for assessing the biodegradability of plastics that sink and settle on the seabed, such as fishing gear, agricultural films, or packaging debris. The method measures oxygen consumption in a closed respirometer to quantify the ultimate biodegradation of these materials in coastal or marine sediment environments.
