Elective Courses 

Remaining 4 units may be taken from the courses list as below offered in the MPH curriculum. Some courses may not be offered during every academic year. Please contact the MPH office for the latest information.


OENV5001 Environmental Health Sciences

2 units (Compulsory MPH Course)

This course addresses how the environmental and occupational (work-related) factors affect human health and what we can do to prevent or minimize the negative impacts. It examines the environmental health issues and recent development in industrialized and developing countries. It also covers risk communication, environmental health policy, and emerging environmental health problems.

OENV5002 Lecture series in Occupational Health

3 units (Pre-requisite: OENV5001) A basic course for students intending to study in any discipline of occupational health. General basic principles of controls of hazards in the practice of occupational health and hygiene will be introduced. Other topics include chemical hazards, physical hazards, biological hazards, ergonomics, injury and return to work, workplace wellness, as well as common occupational diseases and challenges in Hong Kong.

OENV5006 Air Pollution

2 units (Pre-requisite: OENV5001)​ This course introduces the current state of knowledge in the key areas in which air pollutants impact on the health of the general population. Topics include the health impacts of gaseous air pollutants such as sulfur dioxide, nitrogen dioxide, carbon monoxide and ozone; mechanism of lung injury by airborne particulate matter; epidemiological evidence of the risk from particulate matter exposure; airborne chemical carcinogens; health effects of indoor air pollution; and setting health-based air quality standards.

OENV5008 Water and Health

2 units The course gives a brief introduction to water, environment, and health. Students will be able to understand the importance of water in human health, describe problems of water, sanitation and hygiene in urban slum population, understand effect of heavy metal poisoning from industrial and agricultural pollution, describe common diarrheal diseases, their prevention, and how climate affects infectious diseases.

OENV5009  Public Health Toxicology

2 units (Students are required to have good knowledge on biology and health or have taken PBHT5005 Basic Human Physiology).

This course teaches students the basics of basic concepts of toxicology and its application to environmental, occupational, nutrition and food toxicology; discuss distribution, cellular penetration, metabolic conversion, and elimination of toxic agents, as well as the fundamental laws governing the interaction of foreign chemicals with biological systems; focus on the application of these concepts to the understanding the result from environmental exposure to toxic substances through a case study format.

OENV5010 Environmental Risk Assessment

2 units (Pre-requisite: OENV5001). This course provides students with an understanding of the role and scope of health risk assessment, the application of toxicology, epidemiology, exposure assessment and environmental monitoring in risk assessment, risk characterization and risk management.

OENV5011 Environmental Risk Management and Communication

2 units (Pre-requisite: OENV5001 and OENV5010)

This course builds upon the principles taught in OENV 5010 (Environmental Risk Assessment). The course gives students basic knowledge of the frameworks used for risk reduction and the protection of human health from chemical, physical, biological and ergonomic hazards. Students will be exposed to environmental risk communication frameworks and practical guidance on report writing for stakeholders and for future policy formulation.
