Abstract

In this paper, we introduce a real-time monitoring system for the toxicity assessment of chemicals using Daphnia as an educational tool to encourage an interest in science among junior high school students. The swimming behavior of Daphnia is observed through a web camera after a toxic substance is added to water. The toxicity level of the chemicals is estimated from the survival time of Daphnia in the water containing the toxic substance.

Keywords: Real-time monitoring system, Toxicity assessment, Environmental education
