Environmental Monitoring

Definition

Environmental monitoring refers to the systematic process of assessing and analyzing various environmental factors to ensure public health and safety, as well as compliance with environmental regulations. This can include measuring pollutants, monitoring ecosystem health, and observing changes in environmental conditions. Such monitoring is crucial for understanding the impacts of human activities on ecosystems and helps in making informed decisions for environmental management.
