CHM 300-Detection and Monitoring of Toxic Products and By-Products in The Environment.

Environmental monitoring describes the processes and activities that need to take place to characterize and monitor the quality of the environment. Environmental monitoring is used in the preparation of environmental impact assessments, as well as in many circumstances in which human activities carry a risk of harmful effects on the natural environment. All monitoring strategies and programs have reasons and justifications which are often designed to establish the current status of an environment or to establish trends in environmental parameters. In all cases, the results of monitoring will be reviewed, analyzed statistically, and published. The design of a monitoring program must therefore have regard to the final use of the data before monitoring starts. The monitoring and control of environmental hazards to health entails a wide range of actions, each tailored to the particular hazard or form of public health concern.  Monitoring implies use of routine measurements to detect changes in the environment or health, and can be based on data from a wide variety of sources.
