利用鱼的活动电位监测原水有毒物质

Monitoring the toxicant of source water using the active electrical potential of fish

本方法是利用鱼类对有毒物质进入水体后引起活动电位变化,来自动连续监测水质的情况。以鱼在水中活动时产生的活动电位作为数学变量,根据其在正常情况下和有毒物质污染情况下的变化,应用计算机技术对该变量进行连续采集、运算、分析处理、控制,从而达到连续监测、及时自动预警、报警、采样的作用。

The method proposed in this paper can continuously and automatically monitors source water by using the vari- ation of active electrical potential of fish when source water is polluted by toxicant. For normal and polluted source waters, the active electrical potentials of fish are different. The active electrical potentials of fish,which can be quantified as average displacement values, can be continuously collected, calculated and analyzed by using computer technology. Then the purpose of continuous monitor, the automatic early warning and alarm can be achieved.
