| Research Abstract |
This research was aimed to develop a new approach for monitoring aquatic toxicants by using protozoan cells. A measuring device and a computer program were newly developed to monitor various morphological and electrical parameters of free-living protozoan cells in suspension. In order to evaluate feasibility of this system, Euglena gracilis was used as a test organism. As a result, the dielectric method presented here appeared to be applicable for monitoring toxicity on the cell shape and electrical properties of the plasma membrane and cell organelles.
