摘要
针对突发水污染事件难以准确预警的现状,通过模拟水体突发汞污染事件,开展了以生物鱼行为变化为基础的水质生物预警技术研究。以正常水体中斑马鱼的行为变化为基础,采用高速摄像跟踪技术,解析了突发汞污染(0.1mg/L)水体中斑马鱼游动行为(游动速度、高度、转弯次数、加速度)和通讯行为(平均距离、分散度)等行为指标的变化,结果表明:综合评价指标水质健康指数6h内无法预警,以游动高度作为水体突发汞污染事件的监测预警指标,可将预警时间缩短至3h。
In view of the present situation that early warining of sudden water pollution is difficult,this paper simulates sudden mercury pollution to conduct the research on biological early warning technology based on fish behavior.Based on the behavior changes of zebrafish in normal water,the paper captures and analyzes the swimming behaviors（swimming speed,swimming depth,turning frequency and accelerated speed）and fish school behaviors（average distance,dispersion）of zebrafish under 0.1mg/L mercury exposure by high-speed photography tracking technology.The results show that early warning of mercury pollution could not be identified in six hours by comprehensive evaluation index,namely,water quality health index.By taking the swimming height as the monitoring indicator for sudden mercury pollution of waterbody,early warning time could be shortened to three hours.
