Gas stoves increase nitrogen dioxide exposure above WHO standards – study (www.theguardian.com)

Science Advances report also finds people of color and low-income residents in US disproportionately affected

Using a gas stove increases nitrogen dioxide exposure to levels that exceed public health recommendations, a new study shows. The report, published Friday in Science Advances, found that people of color and low-income residents in the US were disproportionately affected.

Indoor gas and propane appliances raise average concentrations of the harmful pollutant, also known as NO2, to 75% of the World Health Organization’s standard for indoor and outdoor exposure.

That means even if a person avoids exposure to nitrogen dioxide from traffic exhaust, power plants, or other sources, by cooking with a gas stove they will have already breathed in three-quarters of what is considered a safe limit.

“When you’re using a gas stove, you are burning fossil fuel directly in the home,” said Yannai Kashtan, lead author of the study and a PhD candidate at Stanford University. “Ventilation does help but it’s an imperfect solution and ultimately the best way is to reduce pollution at the source.”

I'm guessing this is a non issue in a well ventilated area?

[–] Soggy 6 points 7 months ago

"Well-ventilated" being a higher standard than you'd probably expect, but yes. Standard over-range extractor isn't doing enough.

It's like you didn't even read the pithy article much less the study behind it.

"study"

[–] inclementimmigrant -1 points 7 months ago (1 children)

I mean feel free to push back on any of the data the study provided. I mean I thought they could have done a better job with the effects of having a range hood but since that has been studied elsewhere and cited, I feel that it was acceptable with the scope they outlined.

[–] afraid_of_zombies 1 points 7 months ago (1 children)

I really shouldn't have to. As the study noted the homes they found with poor indoor quality had poor outdoor quality. Which means the oven really has little to do with it.

NOX is a product of incomplete diesel consumption. Do you want less NOX? Newer tighter regulations on trucks and give cops the power to pull over any truck with obvious air problems. After you do that let me know what the data in poor industrial areas shows. This whole study is garbage, it's like proving that homes without air-conditioning are hotter than homes with it, int eh same area. Yeah kinda figured.

Oh and don't give me any bullshit about how trucks can't get NOX down. All ships flagged in the EU did it 6 years ago.

WTF are you talking about? You're not even in the realm of the study anymore with your rantings here.

from the abstract:

Gas and propane stoves emit nitrogen dioxide (NO2) pollution indoors, but the exposures of different U.S. demographic groups are unknown. We estimate NO2 exposure and health consequences using emissions and concentration measurements from >100 homes, a room-specific indoor air quality model, epidemiological risk parameters, and statistical sampling of housing characteristics and occupant behavior. Gas and propane stoves increase long-term NO2 exposure 4.0 parts per billion volume on average across the United States, 75% of the World Health Organization’s exposure guideline. This increased exposure likely causes ~50,000 cases of current pediatric asthma from long-term NO2 exposure alone. Short-term NO2 exposure from typical gas stove use frequently exceeds both World Health Organization and U.S. Environmental Protection Agency benchmarks. People living in residences <800 ft2 in size incur four times more long-term NO2 exposure than people in residences >3000 ft2 in size; American Indian/Alaska Native and Black and Hispanic/Latino households incur 60 and 20% more NO2 exposure, respectively, than the national average.

They took samples before and after gas stoves were turned on inside various rooms in various houses and they state all of that in the study that that shit came from the stove and increased the levels of NO2 above WHO standards and not the outdoor environment. They're stating that gas stoves are problematic especially in lower income dwellings.

Also FTFS:

Consistent with previous research (10, 24, 25), we find that combustion from gas and propane stoves represents a major source of long- and short-term NO2 exposure that can exceed U.S. and WHO guidelines just by using a stove, independent of any outdoor NO2 exposures.

So again WTF are you on about?

N=18. No control.

Not convinced.
