Water quality. Determination of inhibition of gas production of anaerobic bacteria - Test for low biomass concentrations Ingestion-build-67170 Why should you use BS1 Scope This part of ISO 13641 specifies a screening method for assessing the potential toxicity of substances, mixtures, surface waters, groundwaters and wastewaters, effluents, sludges, or other environmental samples by determining the production of biogas (carbon dioxide and methane) from muds, sediments and other anaerobic environments with low biomass concentration. The growth rate of anaerobic bacteria is much lower, compared with that of
