This report focuses on environmental issues that are of particular concern to the health of Canadians. It begins with a review of the range of factors that can influence health and a general description of the process of health risk assessment and management. Subsequent chapters provide information on key health risks associated with the natural environment (air, water, food, soil) and describes the impact of the human-built environment on health. Topics covered include pollutants, hazardous substances, climate change, water-borne diseases, biological agents, major initiatives to protect health, urban systems, housing and the home environment, work and school environments, transportation, human-made sources of radiation, and environmental emergencies. A final summary provides highlights from the report, describes the future challenge of achieving sustainable development in the context of health and the environment, and notes efforts made by federal government departments in this regard. Includes glossary.
Second national state-of-the-environment report, addressing the questions of what is happening in Canada's environment, why it is happening, why it is significant, and what Canadians are doing about it. The report is divided into five parts, dealing with perceptions of the environment and the dangers inherent in our tendency to look at the world in terms of human economic models; exploring the state of particular environmental components and the major sectors of human activity; describing six regional case studies; addressing six important environmental issues; and discussing the concept of sustainable development and its implications for Canada's future.
Air pollution is a global hazard. Majority of the world’s population is affected by air pollution. Contamination of air is no more an only an atmospheric problem but now has become a health concern too. Under the Clean Air Act of 1971, a set of air pollutants are designated as criteria pollutants. These are suspected to be strongly harming the public health and the environment as compared to other primary and secondary pollutants. Globally, this category of air pollutants has been given less attention, only few studies have been reported in this area. This book begins with a short background on criteria air pollutants and their sources, sinks and chemistry. The chapters explore the detailed nature of primary pollutants criteria pollutants such as nitrogen dioxide, sulphur dioxide, carbon monoxide, particulate matter and lead. Their reaction mechanisms, climate change potency, environmental health effects on plants and human life are discussed. The book also covers secondary pollutants such as ozone. The book discusses ozone chemistry and its environmental health effects. This book act as a valuable tool for students in Environmental Science, Biological Science and Agriculture, as well as environmental consultants and professionals involved in air quality research and the application of air quality guidelines and advice.
