  • 1973 ----- color ----- 8 min ----- 16mm
  • Pollutants in water are not merely a matter of life and death. Long-term effects can severely influence fish populations. Research techniques in a modern physiology laboratory are examined. Fish with a variety of sensing devices implanted to monitor heart rate, blood pressure, blood oxygen levels and breathing movements are subjected to different types and levels of pollutants in order to determine the acceptable concentrations.
