要約(英語): As cases of accidental water contamination caused by factory disposal and other influences are reported often, early detection of contamination is becoming an important issue in terms of safe water supplies and environmental protection. In recent years, bioassay systems have attracted attention because they enable water quality assessment based on the biological responses of fish, thereby removing the need for chemical examination. In this regard, several bioassay systems premised on the monitoring of swimming behavior or bioelectrical signals as indicators of contamination have been proposed. However, conventional systems can overlook contamination that affects non-monitored indicators. This paper proposes a bioassay system allowing simultaneous monitoring of swimming behavior and bioelectric signals from small fish. The results of experiments on 10 test fishes confirmed that the system can detect contamination within 10 minutes of 0.5% ethanol being added. These outcomes validated the applicability of the proposed system for the detection of water contamination.
