The basic methods of environmental epidemiology research include

Descriptive research, analytical research and experimental research

Environmental epidemiology is a science that applies traditional epidemiological methods and combines the characteristics of the relationship between environment and population health to study the relationship between external environmental factors and population health from a macro perspective. According to the contents of environmental epidemiology research, different epidemiological methods are selected. If the environmental exposure factors are known, to study the harm and degree to people's health, current research, group research and experimental research can be used. To explore the environmental pathogenic factors after abnormal health or clinical manifestations, we can first carry out current research and case-control research to obtain the relationship between health exposure effects and find out the main risk factors leading to abnormal health and clinical manifestations, and then choose cluster research or experimental research to confirm.
