Air Pollution In Windsor: Understanding The Root Causes

Air pollution is a pressing issue in Windsor, Ontario, Canada, with far-reaching health and economic impacts. The city's air quality is influenced by a combination of local and regional factors, including emissions from transportation, local power plants, and industrial activities. The effects of air pollution are exacerbated during extreme heat, particularly affecting individuals with pre-existing heart and lung conditions. With the costs of air pollution exceeding $1 billion annually in Ontario, addressing this issue through regional collaboration and local initiatives is imperative.

Local transportation and trade

The third major source of air pollution in Windsor is local transportation and trade. The Windsor-Detroit gateway is the busiest international trade corridor in North America. In 2005, over 16 million cars and trucks crossed the Windsor-Detroit gateway. The number of vehicles on the road at any given time, from smaller personal vehicles such as cars to massive heavy-duty vehicles such as trucks and lorries, contributes to emissions from vehicles. These larger vehicles often run on diesel fuel and can emit far more chemical pollutants and hazardous particulate matter than smaller vehicles. The presence of these larger vehicles is also increased by any industrial imports or exports being transported across the city.

To address this issue, the City of Windsor has taken an important first step by purchasing 18 hybrid electric buses, representing an immediate conversion of 18% of Transit Windsor's fleet to hybrid technology. These new buses use significantly less fuel than regular buses and are expected to generate public interest and support for further improvements in fuel efficiency.

Coal-powered electricity generating stations

Much of the air pollution in Windsor comes from upwind sources, including coal-powered electricity generating stations. While the specific coal-powered stations affecting Windsor are not named, it is known that industries and cities in Michigan and the Ohio Valley are contributors.

Coal-fired power plants are a major source of air pollution, emitting over 4 million tons of harmful pollutants into the atmosphere annually. These emissions include particulate matter (PM), nitrogen oxides (NOx), sulfur dioxide (SO2), carbon monoxide (CO), and other hazardous air pollutants. The combustion of coal releases these pollutants into the air, causing significant health and environmental issues.

Particulate matter, a mixture of solid particles and liquid droplets, can be released directly into the air or formed in the atmosphere as a result of chemical reactions. Inhalation of PM can lead to respiratory and cardiovascular problems, with prolonged exposure increasing the risk of lung cancer. Nitrogen oxides contribute to the formation of ground-level ozone, a major component of smog, which irritates the respiratory system and exacerbates lung diseases.

Sulfur dioxide, another byproduct of coal combustion, poses risks to human health and the environment. High concentrations of SO2 can irritate the eyes, nose, and throat, leading to respiratory issues. Additionally, SO2 contributes to the formation of acid rain, which damages ecosystems, harms aquatic life, and erodes buildings and structures.

Carbon monoxide (CO) released from coal-powered stations is harmful to human health as it reduces the blood's ability to transport oxygen, causing headaches, dizziness, and nausea. Prolonged exposure to elevated CO levels can lead to more severe health issues, including brain damage and death.

To address the air pollution caused by coal-powered electricity generating stations and other sources, the City of Windsor is taking several measures. They have begun developing a Heat Alert and Response System (HARS) with Health Canada's support to mitigate the impacts of extreme heat on residents' health. Additionally, the city is partnering with other municipalities in South West Ontario to form a regional Clean Air Partnership, aiming to leverage resources, foster collaborations, and drive collective action to improve air quality.

Meteorological conditions

The air pollution affecting Windsor comes from a combination of local and non-local sources. While the city is taking steps to address the issue, meteorological conditions play a significant role in exacerbating the problem.

During the colder months, there is an increased demand for energy, which results in more fuel being burned to meet these needs. This leads to an increase in emissions from local power plants, which contribute to the overall air pollution in the region. The combustion processes involved in generating electricity from fossil fuels release various chemical pollutants into the atmosphere, negatively impacting air quality.

Additionally, meteorological conditions, such as wind patterns, can carry air pollution from upwind sources, including industrial areas in Michigan, Ohio, and New York, directly into Windsor. The prevailing winds can transport large clouds of smoke and haze from these heavily industrialized areas, adding to the local pollution levels in Windsor.

Furthermore, extreme heat and humidity can worsen the effects of air pollution on human health. The City of Windsor has recognized this issue and is developing a Heat Alert and Response System (HARS) with the support of Health Canada. HARS aims to help residents identify impending heatwaves, provide a response plan to mitigate the negative health impacts, and educate the public on making informed decisions during extreme heat events.

It is worth noting that while Windsor experiences higher levels of air pollution towards the end of the year, with December being the most polluted month, the city's air quality is generally acceptable for most individuals. However, sensitive groups, including those with heart and lung conditions, may experience symptoms even with short-term exposure to pollutants.

Industrialized areas in neighbouring US states

The air pollution in Windsor, Ontario, Canada, is a regional issue influenced by neighbouring US states. Located near the US border, Windsor is impacted by emissions from industrialized areas in Michigan, New York, and Ohio. These states are suspected of creating large clouds of smoke and haze, which are then carried by winds into Windsor, contributing to the city's air pollution.

Michigan and the Ohio Valley are significant sources of cross-border emissions, with their industries and cities emitting pollutants that affect Windsor. The state of New York is also believed to contribute to the haze and smoke affecting Windsor. These external sources of pollution add to Windsor's local pollution, primarily from transportation and local power plants.

The Windsor-Detroit gateway, as North America's busiest international trade corridor, plays a crucial role in regional air pollution. In 2005, over 16 million cars and trucks crossed this border point, emitting pollutants that affect the air quality in Windsor. Additionally, local transportation, including smaller personal vehicles and heavy-duty vehicles like trucks and lorries, further exacerbates the problem.

Local power plants in Windsor, which utilize fossil fuels such as coal, also contribute to the city's air pollution. The growing population's energy demands, especially during colder months, lead to increased fuel combustion and the release of various chemical pollutants. These emissions, combined with those from neighbouring US states, have a significant impact on Windsor's air quality.

The effects of air pollution are far-reaching, with annual costs exceeding $1 billion in Ontario due to hospital admissions, emergency room visits, and absenteeism. The Ontario Medical Association has published research highlighting these impacts, and the Clean Air Council has been established to address the issue through collaboration and collective action.

People with pre-existing heart and lung conditions are most affected

The elderly, in particular, are gravely affected by air pollution, with any subsequent respiratory ailments that may be inflicted upon this community sometimes having terminal consequences. The Ontario Medical Association has published research on the health effects of air pollution, which includes hospital admissions, emergency room visits, and absenteeism. The economic impact of air pollution in Ontario is estimated to exceed $1 billion annually.

Air pollution in Windsor is caused by a combination of upwind sources, such as coal-powered electricity generating stations and industries in Michigan and the Ohio Valley, as well as local transportation emissions and emissions from local power plants.
