Water quality. Sampling - Guidance on biotesting of samples Ingestion-build-181247 It establishes a general model1 Scope This document gives practical guidance on sampling, pre treatment, performance and evaluation of environmental samples in the context of performing biological tests. Information is given on how to cope with the problems of biotesting arising from the sample and the suitability of the test design. It is intended to convey practical experience concerning precautions to be taken by describing methods successfully proven to solve or to circumvent
