Environmental monitoring is a subject that uses modern scientific and technological means such as chemistry, physics, biology, medicine, telemetry, remote sensing and computer to monitor, measure and monitor various marker data reflecting environmental quality and its changing trend, so as to make a comprehensive evaluation of environmental quality.
It includes not only the detection of chemical pollutants and the monitoring of physical factors such as noise, vibration, heat energy, electromagnetic radiation and radioactivity, but also the biological monitoring of various reflections and information tests caused by environmental quality changes, as well as the ecological monitoring of regional communities and population migration changes.
