A NEW TYPE OF RESPIROMETER FOR TOXICITY TEST
一种新的生物毒性试验方法

A respirometer has been developed for toxicity test based on the principle of fuorescence quenching by oxygen. Toxicity can be assessed by the respirometer according to the cell respiration inhibition percent of toxicant on microorganisms used in the toxicity tests. The effects of some heavy metals on activated sludge, soil bacteria , and E coli were tested with the respirmeter. It is feasible to conduct the toxicity test by employing the respirmeter.It has unique advantages in sensitivity and efficiency. The respirometer can be expected to be a promising device for large scale toxicity test and environmental monitoring.
