Aerosol is a completely Free-and-Open-Source (FOSS) Chrome extension that allows the user to quickly look up for a city's air pollution level in a comprehensive way of representing the quality of air ― which is measured in Air Quality Index (AQI) that accounts for various pollutant's concentrations ― in a scientifically calculated count of Equivalent Cigarettes, based on University of California's research.

Why It Matters

Air quality plays a crucial role in human health. Poor air quality can cause respiratory problems, exacerbate asthma, and lead to chronic conditions like bronchitis. Prolonged exposure to polluted air increases the risk of cardiovascular diseases and other systemic health issues. Vulnerable groups, including children and the elderly, are particularly at risk. Clean air is essential for maintaining healthy lung function and overall well-being. Addressing air pollution through effective policies and individual actions is vital to reducing health risks and improving quality of life.

Research By University of California, Berkley

A study by the University of California, Berkeley, equates Air Quality Index (AQI) levels to cigarette consumption. An AQI of 22 corresponds to smoking one cigarette per day, based on fine particulate matter (PM2.5) concentrations. PM2.5 is a harmful pollutant linked to respiratory and cardiovascular diseases. For example, an AQI of 150, categorized as unhealthy, equals smoking seven cigarettes daily. This metric highlights the health risks of air pollution, emphasizing that prolonged exposure to high AQI levels can lead to severe health issues, including lung cancer and heart disease, similar to the effects of chronic smoking.

Frequently Asked Questions (FAQs)

1. What is AQI and how is it calculated?

   AQI, or Air Quality Index, is a standardized measure used to communicate the quality of air in a specific area. It is calculated based on the concentrations of various pollutants like PM2.5, PM10, ozone, and others, using established health-based thresholds.



2. How does Aerosol convert AQI to equivalent cigarettes?

   Aerosol uses research from the University of California, Berkeley, which correlates AQI levels to cigarette consumption. For example, an AQI of 22 is equivalent to smoking one cigarette per day, based on PM2.5 concentrations.



3. Is Aerosol available for browsers other than Chrome?

   Currently, Aerosol is only available as a Chrome extension. Support for other browsers may be considered in future updates.
