Abstract
Detection of toxicity of surface and waste waters and other aq. solns. is based on the measurement of the biological oxygen demand of microorganisms. Microorganisms are immobilised on a filter membrane and the respiration intensity of the microorganisms contg, membrane is determined. - This biological cative ''sandwiched'' membrane to complete with an oxygen electrode and the measuring device also contains a nutrient unit and a registering universal titrator.
