Air Quality In Canada

Satisfactory Essays
The U.S. has recently updated critical air quality standards, but Canada's National Ambient Air Quality Objectives date back to the 1970s. Inefficient wood stoves and fireplaces can seriously compromise air quality inside homes, as well as contribute to outdoor air pollution problems. But we often take the air we breathe for granted. The subset of air pollutants that cause smog and acid rain (sometimes referred to as Criteria Air Contaminants or CACs) include: According to the most recent environmental indicators, 5.5 per cent of cardiopulmonary (heart and lung disease related) deaths can be attributed to ground-level ozone exposure, which has increased over the past decade. The Canadian Medical Association estimates that Canada's air pollution…show more content…
Ontario estimates that half of the air pollution in the province blows in from the . Even cleaner-burning wood stoves emit fine particles into the air. In addition, burning wood can release other toxic substances into the air if the wood has been treated with chemicals, glue or paint. These sources are also the leading contributors of greenhouse gases that cause climate change, so taking action on air pollution is win-win. Electricity generation is also a significant source of mercury emissions. In Quebec, it is the leading source of fine particulate emissions associated with human activity, at 47%. This is a significant source of particulate matter pollution in parts of Canada. During the same period, exposure to fine particulate matter has remained unchanged (i.e., did not improve) and accounts for three per cent of cardiopulmonary deaths. It's free, it's all around us and we can't live without it for more than a few minutes. Electricity generation from fossil fuels is responsible for a large share of Canadian carbon monoxide, nitrogen oxides, sulphur dioxide and fine particulate matter emissions. Industrial emissions from the United States also contribute to smog and acid rain in some parts of
