Abstract
A rapid and simple algal toxicity test method based on the oxygen evolution by green algae Selenastrum capricornutum was developed. The effect of the toxicant on the oxygen evolution during a 6-hour incubation period was observed. After obtaining the dose-response relationship, EC50 was calculated and compared with the EC50 of a traditional algal growth test. As the sensitivity of the method developed in this study was as good as that of the traditional one, it can be applied as a rapid and easy toxicity test.
