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."
When wood burns, it produces nitrogen dioxide, which is absorbed by the surface of the meat. This nitrogen dioxide reacts with the myoglobin (a protein found in muscle tissue) to form a stable pink compound called nitrosyl hemochrome. This reaction not only contributes to the pink smoke ring often seen just beneath the surface of smoked meats but also enhances the flavor by adding a distinctive smoky taste.

It’s been a warm and rather humid weekend in Barcelona. Yesterday was particularly stifling, with the heat and lack of breeze making things rather uncomfortable. The Air Quality indicator reached “Poor” largely due to high levels of NO2, no doubt from vehicle exhaust fumes. It surprises me that so many people sit out at the pavement tables outside restaurants having meals when it’s hot and the air is thick with nasty stuff. Al Fresco is supposed to mean “in the fresh air”! I much prefer to dine indoors, unless it’s very late at night.
Today was a little better except that there was resurfacing work going on outside my flat on RambladeCatalunya. I knew it was coming, as they’ve been doing other nearby roads over the past few weekends. It was a little noisy, even on the 6th floor, but that didn’t bother me as much as the tar fumes!
Anyway, all this has made me decide not to attempt to extend my stay here beyond my current lease, which expires at the end of June. I’ll take the last two months of my sabbatical somewhere a bit cooler!

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."
Air pollution linked to increased risk of non-lung cancers in older adults
Chronic exposure to fine particulate air pollutants (PM2.5) and nitrogen dioxide (NO2) may increase non-lung cancer risk in older adults, according to a study led by Harvard T.H. Chan School of Public Health.

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

"In a case study of LA County, we identified comparatively high NO2 concentrations for the property types of food processing facilities and high-density residential complexes (such as high-rise apartments and apartments). This finding provides evidence that these emerging sources may be crucial to mitigate cumulative NO2 exposures and subsequent health risks from a regulatory perspective"

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.
