An on-line monitoring system for the toxicity assessment of chemicals using Daphnia magna was studied. The behavior of Daphnia magna in micro well plates for organophosphorus pesticides (OPs) was observed through a web camera connected to a personal computer. The stock image data were analyzed using a laboratory image analysis program. Daphnia magna showed abnormal behavior, such as a rotational motion, in the presence of OPs. The motion of Daphnia magna in the localized area can be used as an index to determine toxicity to pesticides, which is recognized by our image analysis system. The present method is much more time-efficient than the conventional technique based on Japanese Industrial Standards (JIS).
