All,

I am working on a citizen science project with the Sierra Club's DC Chapter to measure nitrogen dioxide emissions from gas stoves.? All gas stoves emit nitrogen dioxide in varying degrees, and these emissions increase the?risk of asthma.? It turns out that how much nitrogen dioxide a particular stove emits does not depend at all on the age or cost of the stove.? (Spoiler alert: it depends more on the size of your kitchen, whether you have (and use!) a range hood vented to the outside)? I was surprised to learn that emissions levels from ordinary use of a gas stove?can create concentrations of nitrogen dioxide that exceed 100 ppb, the EPA's standard for 1 hour of outdoor exposure to nitrogen dioxide.

If you have a gas stove and you have any interest in having its nitrogen dioxide emissions tested, please let me know.? The Sierra Club has a few handheld NO2 measuring devices and I can schedule a time in the coming?weeks to do it.? It would be after June 7. It will take about 45 minutes total because we test at various intervals after the gas stove and oven are turned on (15 minutes and 30 minutes), and then again 15 minutes after the stove is turned off.??

Thanks everyone,

Cara
