Environmental and occupational health surveillance aims to identify and control health hazards in the environment and workplace, thereby preventing or reducing the occurrence of diseases and injuries.

Data dissemination is not a component of environmental and occupational health surveillance. The other three components are essential for the surveillance process.

Environmental and occupational health surveillance collects data on health outcomes, environmental exposures, and occupational exposures.

Data analysis in environmental and occupational health surveillance serves all of these purposes.

Data interpretation in environmental and occupational health surveillance serves all of these purposes.

Data dissemination in environmental and occupational health surveillance serves all of these purposes.

Air pollution, water pollution, and soil contamination are all examples of environmental health hazards.

Exposure to hazardous chemicals, physical hazards, and biological hazards are all examples of occupational health hazards.

Cancer, respiratory diseases, and cardiovascular diseases are all examples of health outcomes that can be associated with environmental or occupational exposures.

Lack of data, lack of resources, and lack of trained personnel are all challenges in conducting environmental and occupational health surveillance.

Increasing funding, training more personnel, and improving data collection and management systems are all ways to improve environmental and occupational health surveillance.

Environmental and occupational health surveillance can help prevent disease and injury, detect health problems early, and develop targeted interventions.

Privacy and confidentiality of data, informed consent, and justice and equity are all ethical considerations in environmental and occupational health surveillance.

The Clean Air Act, the Clean Water Act, and the Occupational Safety and Health Act all contain legal requirements for environmental and occupational health surveillance.

Increasing use of technology, increasing focus on global health, and increasing emphasis on prevention are all trends in environmental and occupational health surveillance.
