| Outline of Final Research Achievements |
Bioassay monitoring is a method for detecting environmental change using animals. It has an advantage over the traditional chemical analysis methods in continuous monitoring of potential toxicity risks on the animals. Therefore, a bioassay method has been proposed using ventilatory signals of killifish; however, the conventional systems were limited to short-term monitoring. In this study, we developed a system that enables long-term measurement of ventilatory signal continuously. The measurement results demonstrated that the ventilator signal patterns frequently change even under the same water qualities. We also proposed a toxicity detection algorithm for water using one class support vector machine and verified that the algorithm could detect artificial administration of toxic substance within a few hours.
