本文件规定了测定试验海水中未知有毒污染物存在的生物测定法(见图?A.1)。它是基于海洋蓝细菌Cyanobium sp.(NIES-981)的光合活性的抑制。基于延迟荧光(DF)强度确定抑制。该方法快速,比标准生物测定需要更少的实验室空间。因此,它可以在船上使用,为时间和空间极其有限的深海采矿场的海水质量管理生成基本数据。

This document specifies a bioassay for the determination of the presence of unknown toxic contaminants in test seawater (see Figure A.1). It is based on the inhibition of photosynthetic activity of the marine cyanobacterium Cyanobium sp. (NIES-981) by such toxic contaminants. The inhibition is determined based on delayed fluorescence (DF) intensity.The method is rapid and requires less laboratory space than standard bioassays. Hence, it can be used on-board to generate basic data for seawater quality management at deep-sea mining sites where time and space are extremely limited.
