| Abstract |
Biological sensors have been becoming more important to monitor the quality of the aquatic environment, especially the presence of hazardous compounds. This study was designed to develop a biomonitoring system based on the respiratory and movement responses of carp (Cyprinus carpio) to monitor water quality. Diazinon, phenol, cadmium, and LAS were selected as test chemicals and exposure concentrations was ranged from acute toxicity level to one 100th of the highest concentration. When exposed to the acute level concentration, the first response were detected within 3 hr for LAS, 0.5 hr for cadmium and phenol and 15 hr for diazinon in this system. In case of cadmium, the significant response was shown at the chronic level and this system, therefore, could detect not only the acute level of LAS, cadmium, and phenol within 3 hr but also the chronic level of cadmium within less than 4 hr after exposure. In conclusion, present study proved that this biological monitoring system using fish respiration and movement as a sensor could be one of the promising approach to detect and prevent a toxic pollutant release into the aquatic environment. |
