| Abstract: | An apparatus was designed to measure continuously the effects of nominal concentrations of copper, cadmium, phenol, ammonia and cyanide upon breathing rates in largemouth bass. Acute and sublethal toxic effects were indicated in a majority of cases by increased breathing rate. The use of this reaction and the monitoring apparatus to monitor a wide range of industrial pollutants was shown to be practicable. Consideration is also given to its possible application in local situations. |
