Water quality. Measurement of biochemical parameters. Spectrometric determination of the chlorophyll-a concentration Ingestion-build-48974 One target is defined for1 Scope 1. 1 This International Standard specifies a method for the determination of the chlorophyll a concentration. The procedure can be applied for phytoplankton in natural surface waters and for testing algal growth in bio assays. Using appropriate sampling it can also be applied to phytobenthic communities (see annex A).
