Air Pollution (03:07)


Dr. Scott Weichenthal's program at McGill University studies to short-term and long-term health effects of air pollution. In addition to the lungs, air pollution harms cardiovascular health and can increase the risk of dementia.

History of Air Pollution (04:11)

Concerns about air pollution began with the London Fog of 1952, which triggered an increase in air quality studies and an effort to reduce air pollutants. Indoor air pollution is a newer concern with carbon monoxide being the most dangerous.

Dangerous Air Pollutants (01:04)

Combustion processes put small amounts of particles into the air. Everyone is exposed to some amount of dangerous gases and particles.

Air Pollution and Climate Change (02:22)

Many air pollutants, like black carbon, have a direct link to climate change. The planet warming has created environmental factors more likely to produce air pollution.

Air Pollution Effects (07:19)

Though North America has good air quality, residents are still affected by air pollution. People in higher air pollution areas have greater risk of lung cancer, heart disease, and death.

This program gives viewers a thorough overview of air pollution, climate change, and the resulting impact on human health. The study of air pollution began in 1952 with The London Fog, a severe air pollution event primarily arising from the use of coal. For five days, the city of London was brought to a standstill by a dense blanket of toxic smog, killing an estimated 8,000 to 12,000 people. This event spurred action by governments and researchers to minimize air pollution and to protect health. Dr. Scott Weichenthal, associate professor of Epidemiology, Biostatistics, and Occupational Health at McGill University, discusses how a variety of contaminants such as volatile organic compounds, sulfur dioxide, carbon monoxide, nitrous oxide, and particulate matter can impact human health.
