The scale, which runs from 0 to 500, was designed by the #EPA & measures the density of five different #pollutants in the #air: ground-level #ozone, #particulates, #CarbonMonoxide, #NitrogenDioxide & #SulfurDioxide.
Several spots in northeastern Minnesota, closest to the fires recorded had AQI readings well into the “hazardous” range on Wednesday.

YT comments can be aggravating, but I read them anyway because occasionally some interactions are rewarding.
I noticed in the comments on this video there seem to be a number of people who claim that burning methane only emits CO2.
Here is my response:
Burning methane at high temperatures causes a reaction between nitrogen and oxygen in the air which produces nitrogen oxides, including nitrogen dioxide.
Another commenter got into a dispute with me about the exact temperature of combustion in these specific turbines - so I looked into it. TIME magazine did an investigation and asked Univ of Tenn Knoxville researchers to measure air pollution levels around the facility using satellite data. Quote from the article: "They found that average concentrations of nitrogen dioxide have increased by 3% when comparing the periods before June 2024 and afterward. They also found that peak nitrogen dioxide concentration levels have increased by 79% from pre-xAI levels in areas immediately surrounding the data center, and by 9% in nearby Boxtown.
Because high concentrations of air pollutants pose greater health risks than lower concentrations, the researchers said, focusing on these spikes—rather than just averages—offers more meaningful insight into potential health impacts. "
Typically, scrubbers are installed at gas power plants to reduce nitrogen oxide emissions. An article from CNBC reported : "While xAI had previously told Memphis regulators that its turbines would include state-of-the-art pollution controls, known as selective catalytic reduction technology, its supplier, Solaris Energy Infrastructure
told CNBC in June that it did not install such controls in xAI’s “temporary” turbines."TIME magazine article:

London Begins to Breathe Better
A study by the Greater London Authority has shown that the city’s levels of lethal pollutants have substantially decreased since the expansion of the UK capital’s ultra low emission zone (Ulez).
The London-wide zone covers nine million people across 1500 km2, the world’s largest zone of its kind.
The report shows that not only have deprived areas seen some of the biggest improvements but air quality has improved in all areas and at a faster rate than the rest of the country.
Nitrogen dioxide is down 27% since Ulez first came in in 2019. PM2.5’s (small particle emissions) are down 31% in outer London compared to what would have been without the Ulez expansion.
Speaking to the Guardian, Mayor of London, Sadiq Khan said, “When I was first elected, evidence showed it would take 193 years to bring London’s air pollution within legal limits if the current efforts continued. However, due to our transformative policies we are now close to achieving it this year.”

How #AirPollution is causing girls to get their first #periods earlier
New research shows that girls in the US are getting their first periods earlier. Exposure to toxic air is partly to blame.
By David Cox, June 4, 2024
"The same trend has also been noted around the world. South Korean scientists have described with some alarm how the number of girls displaying signs of precocious puberty – either breast development or #menstruation before the age of eight - increased 16-fold between 2008 and 2020.
"We're also seeing that these decreasing ages at puberty are even more pronounced in lower socioeconomic status groups, and ethnic minority groups," says Audrey Gaskins, an associate professor at Emory University in Atlanta, the US. "This has important implications for long-term health."
Researchers like Gaskins are primarily concerned that beginning puberty earlier might trigger a cascade of events which have far-reaching consequences later in adulthood. Emerging data suggests that it may not only curtail the fertility window, particularly if these women then enter menopause sooner, but shorten their lives. Precocious puberty has been repeatedly associated with a higher risk of diseases ranging from breast and ovarian cancers, metabolic syndromes such as obesity and type 2 diabetes, and cardiovascular disease."

"For several decades, scientists around the world have become increasingly concerned by signs that girls are entering puberty at a much younger age compared with previous generations.
From when girls experience their first period, something which scientists term the age of menarche, to commencing breast development, these seminal changes marking the onset of adolescence appear to be taking place progressively sooner.
"American girls today have been estimated to start menstruation up to four years earlier compared to girls living a century ago. In May, new data showed that while girls born between 1950 and 1969 typically began menstruating at 12.5 years, this decreased to an average of 11.9 years for the generation born in the early 2000s.

"Some of the major culprits appear to be #ToxicGases such as #SulphurDioxide, #NitrogenDioxide, #CarbonMonoxide and #ozone, all of which are released into the air either through #VehicleEmissions or waste produced by #Manufacturing Plants. In 2022, a study from scientists in Poland, a country known for its poor air quality due to the prevalence of #coal-burning factories, examined data from 1,257 women, and found a link between greater exposure to nitrogen gases and menstruation occurring before the age of 11."

Industry Knew—and Hid—Dangers of #GasStoves Over 50 Years Ago
Brett WilkinsMar 07, 2023
"Newly uncovered documents published last week by #DeSmog reveal that the leading #GasIndustry trade group knew over 50 years ago that cooking with gas stoves could harm human #health and tried to cover up the evidence.
"The DeSmog revelations regarding the #AmericanGasAssociation (AGA) came as the gas industry is pushing back against climate and public health advocates' efforts to ban new gas stoves amid mounting scientific evidence that the appliances threaten the warming planet and people's health.
"Recent studies—which, among other things, showed that #NitrogenDioxide, #CarbonMonoxide, and ultrafine particles produced by gas stoves cause a range of health problems, including 1 in 8 U.S. cases of childhood #asthma—sparked fast and furious backlash from the gas industry and its congressional boosters.
"'It's less widely known that the gas industry has long sponsored its own research into the problem of indoor air pollution from gas stoves,' wrote DeSmog's Rebecca John. 'Now, newly discovered documents reveal that the American Gas Association was studying the health and indoor pollution risks from gas stoves as far back as the early 1970s—that they knew much more, at a far earlier date, than has been previously documented.""

NASA Maps Reveal #Toxic #Emissions Over Major #US Cities
by Adam Kovac, August 24, 2023
"NASA’s new space-based air pollution monitoring system has sent back its first maps, showing #CarTraffic brings down air quality in several #MajorCities.
"The six maps were made from data from the Tropospheric Emissions: Monitoring of Pollution (#TEMPO), which launched in April. In scans taken over a six-hour period on August 2, high concentrations of #NitrogenDioxide, a toxic #pollutant tied to car and #smokestack emissions, can be seen hovering over #NewYork, #LosAngeles, #LasVegas and #WashingtonDC.
"While the location of #AirPollution shown in the maps isn’t surprising, the data is only the tip of the iceberg for TEMPO, the first space-based instrument designed to continuously monitor air quality over #NorthAmerica. TEMPO principal investigator Kelly Chance said there are currently 50 scientific studies under way that will make use of data generated by the program. The program will truly get underway in October when the instrument will begin transmitting hourly daytime scans."

Regardless of politics, culture wars, and regulations, if you have a gas stove and can replace it or encourage your landlord to replace it, do it
We lived with a gas stove when my kids were 2-8. Every winter one of them would develop a cough that lasted at least a month. My oldest was diagnosed with cough variant asthma
After moving to a home with electric stove, respiratory problems disappeared. No asthma. My $0.02

More and more research about the dangers of nitrogen dioxide from gas stoves. I can't help but wonder if this is one of the reasons that Taiwanese women (including nonsmokers) have such high levels of lung cancer? Moreover, it seems that mechanical ventilation doesn't do much to help reduce #NO2 pollution in the home.
