| Nosaukums | <p>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 <em>Cyanobium</em> sp. (NIES-981) by such toxic contaminants. The inhibition is determined based on delayed fluorescence (DF) intensity.</p> <p>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.</p> |
