Water quality. Determination of inhibition of gas production of anaerobic bacteria - General test Ingestion-build-276583 In the case of difference1 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 the anaerobic digestion of sewage sludge over periods of up to 3 days. The growth rate of anaerobic bacteria is much lower compared with that of aerobic
