The consequences of wildfires for air quality - and why it`s important to have a real-time air monitoring network for wildfire season
Wildfires have a severe impact on air quality and, consequently, on human health. While wildfire smoke’s damage can vary depending on its composition and density across an area, research shows that it may not only have short-term damage but perhaps also a cumulative negative impact on human health. However, by recognizing the need for real-time air quality monitoring to collect data and ...
