Unhealthy Air Quality

Unhealthy air quality refers to atmospheric conditions where pollutant concentrations exceed levels considered safe for human health. This can include particulate matter (PM), ground-level ozone (O₃), nitrogen dioxide (NO₂), and sulfur dioxide (SO₂). Exposure to such pollutants is linked with respiratory and cardiovascular issues, especially in vulnerable populations like the elderly, children, and those with pre-existing conditions.

Climate Change and Air Quality

  • Increased frequency of wildfires due to climate change exacerbates air pollution levels.
  • Extreme weather events, including heatwaves and storms, can disrupt air quality monitoring systems and increase pollutant emissions.
  • Rising temperatures contribute to higher ozone concentrations in urban areas.

Health Impacts

  • Respiratory diseases such as asthma are more prevalent among populations exposed to poor air quality.
  • Cardiovascular issues like heart attacks and stroke are also linked with long-term exposure to air pollutants.
  • Vulnerable groups, including children and the elderly, face increased health risks from unhealthy air quality conditions.
