Foundation Courses 

ENVS 5111 Environmental Health and Safety [3 credits]

This course identifies the potential health and safety hazards in the environment. It also emphasizes on the importance of environmental health and safety (EHS) for moral, legal and financial reasons. EHS systems as well as legislation and public organizations in Hong Kong, China and overseas will also be discussed and compared.


ENVS 5113 Marine Ecotoxicology [3 credits]

This course introduces the impacts and toxic effects of environmental pollutants on growth, morphology and species richness of marine organisms with emphasis at the population, community and ecosystem level. Concepts and methods to assess the impacts of toxicants in marine organisms and environment will also be discussed.


ENVS 5114 Environmental Diseases and Microbiology [3 credits]

This course aims to study microorganisms in the natural environment and their potential impacts on human beings. Pesticides, chemicals, radiation, air and water pollution are the manmade hazards that are believed to contribute to human illness. Microorganisms or environmental agents cause airborne and waterborne infectious diseases as well as microbial biodegradation of pollutants will also be discussed.


ENVS 5115 Food Safety Control [3 credits]

This course provides up-to-date technology, and industrial practices on food safety control. Several international food standards and food safety management systems (e.g. ISO 22000, HACCP), as well as changes in food safety legislation which coupled with a number of high profile food safety issues will be discussed.


ENVS 5116 Case Studies in Environmental Risk Assessment [3 credits]

This course introduces the general principles, processes and methodologies of ERA in different developmental projects locally and globally. Specific socio-economic impacts, environmental law and policy, as well as problems and constraints of ERA implementation will also be discussed and compared through various case studies from developed and developing countries. 


ENVS 5117 Pharmacology, Toxicology and Health [3 credits]

This course offers new perspectives of environmental pharmacology: gene-environment interaction, drug-environment interaction and toxin-environment interaction. It particularly emphasizes on the harmful or toxic effects of drugs on human health and environment as modern pharmaceutical products may place the public at risk through destruction of species and pollution of drinking water supply. Epidemiological and health risk assessment issues in relation to environmental health will also be covered.



Elective Courses

ENVS 5112 Environmental Hazard Identification [3 credits]

This course aims to provide in-depth knowledge on the potential effects of environmental hazards on the abiotic and biotic environment through various routes and does of exposure. Current approaches of managing chemical, biological, physical and mechanical hazards in the environment will be addressed.


ENVS 5118 Conservation and Sustainable Development [3 credits]

This course aims to address the importance of different elements and practices in conserving our biodiversity. It also introduces the concept of sustainable development to meet the future needs and balance the objectives between society, economy and environment. It explores ways of finding solutions to the challenges through the promotion of sustainable development. 


ENVS 5119 Pollution Monitoring and Control [3 credits]

This course introduces environmental consequences of air, water and noise pollution. It also considers theoretical and practical aspects of the design and execution of pollution monitoring programmes. Major issues related to pollution control, such as pollution types and sources, technological aspects of pollution control, and pollution-related legislation and regulations will be discussed.


ENVS 5120 Occupational Health and Safety [3 credits]

This course is a survey course on occupational health and safety. It is intended to provide students with basic knowledge of hazardous agents encountered in the work environment, how to define the levels of hazard and determine if conditions comply with legal requirements. It will also cover various hazards control principles and technologies.


ENVS 6111 Environmental Health Research Project [3 - 6 credits]

This course enables students to conduct an independent research project in selected areas of environmental health and safety or related topics under the supervision of one or more Faculty members. Students will demonstrate their initiative and intellectual achievement of the investigation through the application of skills and knowledge leant from the courses. They can develop their abilities to present findings in a precise and coherent manner.


EVSM 5220 Advanced Environmental Chemistry [3 credits]

The course provides an in-depth coverage of topics on inorganic and organic environmental contaminants, their structures, functions, sources and emissions, distribution, transformation and fate in the environment.


EVSM 5230 Environmental Health and Management [3 credits]

The course will give an overview on environmental health and management, including topics on outdoor and indoor environments, workplace environment, water and sewage, food, solid waste, hazardous wastes, vectors and control, radiation, environmental health standards, natural and manmade disasters, risk assessment and management, etc. Each topic will include nature of the issue, known and potential health effects, control and regulatory approaches. More in-depth discussions will be given to occupational health hazards, with emphases on current control methods and technology.


EVSM 5270 Environmental Law [3 credits]

The course will provide students with the basic legal concepts which include the hierarchy of courts in Hong Kong, the difference between civil and criminal proceedings and their possible redresses or remedies available from the courts. Some important provisions of the basic environmental legislation in Hong Kong, environmental prosecution policy of Hong Kong and how to instigate a judicial review against a ministerial decision relating to the environment will also be covered in the course.


JEVE 5320 Water Quality and Assessment [3 credits]

Water quality standards, chemical, physical and biological contaminants in water. General laboratory measurements and instrumental analysis based on optical, electrical and chromatography methods. Toxicity and BOD tests. Pathogenic micro-organisms and microbial examination of water. Environment sampling and quality control and assurance.


JEVE 5420 Biological Waste Treatment and Management [3 credits]

Principles of secondary, biological treatment processes, including sewage sand filters, trickling filters, activated sludge plants, lagoons, ponds, rotating biological contactors, aerobic and anaerobic digesters, and biological nutrient removal. Management of waste treatment systems and works.
