ISO 21338:2010规定了动力学直接接触法，用于测定沉积物和其他固体样品悬浮液的抑制作用，以及有问题的混浊或有色水样品对海洋细菌费氏弧菌发光的抑制作用（NRRL B？11177）。 该方法适用于:a）沉积物样品和沉积物的水悬浮液（淡水、微咸水和海水沉积物）；b） 废水（尤其是混浊和有色的）；c） 土壤、固体废物和其他固体物质（尤其是浑浊和有色）的水提取物（例如沥滤液、淋洗液、淘洗液）。

ISO 21338:2010 specifies the kinetic direct？contact method for determining the inhibitory effect of suspensions of sediment and other solid samples, and also for problematic turbid or coloured aqueous samples on the light emission of the marine bacterium Vibrio fischeri (NRRL B？11177). This method is applicable to: a) sediment samples and water suspensions of sediments (fresh water, brackish, and seawater sediments); b) effluents (especially turbid and coloured); c) aqueous extracts (e.g. leachates, eluates, elutriates) of soil, solid waste, and other solid material (especially turbid and coloured).
