About This Item

 

Full Description

SAME AS ISO 13641-1

This part of ISO 13641 specifies a screening method for assessing the potential toxicity of substances, mixtures, surface waters, groundwaters and waste waters, 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 microorganisms. For this reason the test periods in anaerobic methods are longer than in those with aerobic bacteria.
