Water quality - Guidance standard for the routine sampling and pretreatment of benthic diatoms from rivers
Preview
Summary
This guidance standard establishes a method for sampling and laboratory preparation of benthic diatoms for water quality assessments and studies of temporal change in running waters. It is suitable for use with indices based on the relative abundance of taxa. With appropriate modifications the method can be applied to the study of benthic diatoms in lakes.
