The electrodes are connected with the tail ends of the three leads and are made of silver fine needles, the diameter of each silver needle is 0.25mm, and each silver needle is provided with a needle point so as to penetrate into the heart cavity of the fish body.

Wherein, in order to guarantee the online monitoring and analysis aiming at the sudden water pollution accident, the online water quality monitoring and evaluating system is divided into two operation modes: in the first system, each instrument can normally operate to monitor water quality, various water quality indexes are monitored on line in real time, and the water quality is comprehensively and specifically monitored. But this mode is relatively power-intensive, etc. The second mode is that the water quality is monitored by normal operation of the conventional five parameters, namely temperature, turbidity, pH, conductivity and ammonia nitrogen, and if the electrocardio index is abnormal, the water quality monitoring instrument is started to start comprehensive monitoring and analysis.
Under the stress of different heavy metal pollutants, the electrocardio of the zebra fish can be changed differently. The QRS interval and heavy metal pollutant stress have obvious correlation, and the heavy metal pollutants in the water quality can be monitored by researching, observing and analyzing the QRS interval. The QT interval and organic pollutant stress have obvious correlation, and organic pollutants in water can be monitored by researching, observing and analyzing the QT interval. Therefore, the abnormality of the electrocardio-parameters can be combined to judge whether the pollutant is organic matter or heavy metal. And further, specific monitoring results of the water quality parameter heavy metal sensor and online analysis results of TOC and COD are integrated, so that specific pollutant types and pollution amount ranges are further determined, and online monitoring and evaluation aiming at water body pollution accidents are timely, efficiently and accurately realized. Wherein, a real-time online water quality sampling technology is provided, and the electrocardio abnormality is a switch for automatically sampling water quality. Therefore, once the electrocardio parameters are found to be abnormal through the monitoring and analyzing platform, the water quality can be sampled on line in real time.
Taking the pollutant as an organic pollutant, namely deltamethrin, as an example, when the system operates in the first mode, the chemical index monitoring system, the biological index monitoring system and the water quality evaluation system all operate normally, and the water quality is monitored in real time. If organic matter deltamethrin appears, various chemical indexes can change, and the electrocardio shows that the amplitudes of P waves, Q waves, R waves, S waves and T waves are reduced along with the increase of the concentration of the deltamethrin through analysis data of the electrocardio, and the duration of PR intervals, QRS intervals, ST intervals and QT intervals is increased along with the increase of the concentration of the deltamethrin. Wherein the correlation analysis of QT interval and ambient pressure (E) based on linear regression shows that P-wave and R-wave have significant correlation with deltamethrin ambient pressure (E), while QT interval has very significant correlation with ambient pressure (E), so that the QT interval has obvious correlation with organic pollutant stress. The QT interval allows monitoring of organic contaminants in water. Therefore, the abnormality of the electrocardio-parameters can be combined to judge whether the pollutant is organic matter or heavy metal.
And further, specific monitoring results of a water quality parameter heavy metal sensor are integrated, or online analysis results with higher values of indexes of TOC and COD are generated, so that specific pollutant types and pollution amount ranges are further determined, and online monitoring and evaluation aiming at water body pollution accidents are timely, efficiently and accurately realized. And once the electrocardio index is abnormal, the automatic water sampling is started, a water sample is collected and analyzed, and the pollutant types of sudden pollution accidents are comprehensively detected. When the system operates in the second mode, if the water quality is normal and pollution-free, only the normal five parameters, namely temperature, turbidity, pH, conductivity and ammonia nitrogen, operate normally to monitor the water quality, but the rest chemical index monitoring does not operate. If the electrocardio index is abnormal, the water quality monitoring instrument and the automatic water quality sampling can be started to comprehensively monitor and analyze the water quality.
The QRS interval and heavy metal pollutant stress have obvious correlation, and the heavy metal pollutants in the water quality can be monitored by researching, observing and analyzing the QRS interval. There is a clear correlation between QT interval and organic pollutant stress. The QT interval allows monitoring of organic contaminants in water. Therefore, the abnormality of the electrocardio-parameters can be combined to judge whether the pollutant is organic matter or heavy metal. And further, specific monitoring results of a water quality parameter heavy metal sensor or online analysis results of TOC and COD are integrated, so that specific pollutant types and pollution amount ranges are further determined, and online monitoring and evaluation aiming at water body pollution accidents are timely, efficiently and accurately realized. Wherein, a real-time online water quality sampling technology is provided, and the electrocardio abnormality is a switch for real-time online sampling. Therefore, once the electrocardio parameters are found to be abnormal through the monitoring and analyzing platform, the water quality can be sampled on line in real time. And further, specific monitoring results of the water quality parameter heavy metal sensors or online analysis results of TOC and COD are integrated, so that specific pollutant types and pollution amount ranges are further determined, and online monitoring and evaluation aiming at water body pollution accidents are timely, efficiently and accurately realized. Wherein, a real-time online water quality sampling technology is provided, and the electrocardio abnormality is a switch for automatically sampling water quality. Therefore, once the electrocardio parameters are found to be abnormal through the monitoring and analyzing platform, the water quality can be sampled on line in real time.
