ABSTRACT:
Sample water is introduced into a water bath in which aquatics live, and a gas sparingly soluble in water and giving no effect upon biological activities of aquatics is supplied to the water bath. The supplied gas and carbon dioxide gas generated by the biological activities of aquatics are collected, and a change in water quality of the sample water is detected from a concentration of carbon dioxide thus collected.
Change in water quality of sample water can be rapidly detected thereby, which can be applied to detection of whether toxic materials are contained, for example, in river water flowing into a water purification plant, or not.
