Environmental Monitoring

15.6.2.1. Air and Water Monitoring

Another assay situation that may involve a considerable degree of the unknown is that of environmental monitoring. The primary measurement medium here will be water or air, but the variety of target analytes is vast. At sites of potential pollution, such as in factory effluent, it would be desirable to install online real-time monitoring and alarms, aimed at specific analytes, but in many cases random or discrete monitoring of both target species and general hazardous compounds would be sufficient. The possible analytes include biological oxygen demand (BOD) which provides a good indication of pollution, atmospheric acidity, and river water pH, detergent, herbicides, and fertilizers (organophosphates, nitrates, etc.). The survey of market potential has identified the increasing significance of this area and this is now substantiated by a strong interest from industry.
