An unplanned experiment when wildfire smoke rolled through Colorado shows how trees keep some of the smoke out.
As communities are exposed to wildfire smoke more regularly and over longer durations year after year, it is critical to consider what these changing exposure patterns mean for our long-term health.
The first thing to remember is that all smoke is harmful. Typically, if you can smell smoke, it’s at a level where it’s impacting your health.
Breathing wildfire smoke can cut years off people’s lives. As fires become more frequent in a warming world, smoke is leading to a public health crisis, harming people far from the flames.
States could be in for another summer of unhealthy wildfire smoke as ‘zombie fires’ resurface in western Canada and more blazes break out in the dry conditions.
For decades, big-box retailers have evaded federal regulation of the pollution their operations generate. But a new air emission rule in Southern California could become a model for state controls.
Reducing particle pollution can save thousands of lives, but states need more data to inform better controls. An atmospheric scientist explains what data and actions are needed.
Smoke from bushfires can travel significant distances and reduce air quality throughout a city or region.
On Feb. 7, 2024, the EPA strengthened the federal limit for annual levels of fine particulate air pollution, or PM2.5. Many serious health effects have been linked to PM2.5 exposure.
Researchers created a layer of human lung cells and exposed them to different pollutants.
The longest-running study of its kind reviewed death records in the path of pollution from coal-fired power plants. The numbers are staggering − but also falling fast as US coal plants close.
People with a lung condition are among those particularly vulnerable to bushfire smoke. But you can prepare for the season ahead.
Thick smoke pouring in from Canada’s wildfires canceled baseball games and pushed air quality in major US cities to the worst in the world.
The notion that wildfire smoke is ‘natural,’ and therefore less harmful than other types of air pollution, is not supported by the evidence. Wildfire smoke has been linked to adverse health effects.
Orangutans are vocal animals, so analyzing their calls during events like wildfires can indicate how smoke is affecting their health.
Fires in Canada have sent smoke across several US states, leaving cities including New York, Chicago and Denver with some of the worst air quality in the world – even far from the flames.
We’re all exposed to harmful air pollution when cooking – but retrofitting our homes to save energy may complicate matters.
Fry less, open doors and windows and switch to an electric stove if possible.
Air pollution causes chess players to make more errors – this may have implications for high-skilled professionals.
