"Healthy Air at Home: What You Can Monitor, Filter, and Fix"
Register and more info here:
https://www.thenetwork.to/event-details/healthy-air-at-home-what-you-can-monitor-filter-and-fixfrom the event description:
"Wildfire smoke has changed how a lot of Torontonians think about air quality—checking the day’s PM2.5 levels is now part of our summer routine. Wildfires are mostly out of our control, but you can do something about the air in your home.
Join Louise Hidinger, Clean Indoor Air Toronto founder, Chemistry Ph.D, and science writer, who will walk you through how to monitor and improve your home’s indoor air quality.
You'll leave with a clear understanding of how to guard against the worst sources of air pollution, including the combustion byproducts from your gas-burning appliances."

Here is why you should open your #windows whenever you can. On the left, is 2:05 PM when I’ve had the windows closed all day, the #CO2 levels in the house are high, indicating poor #ventilation. Now swipe to the right image, the levels have dropped to a third after leaving the windows open for over 2 hours, indicating excellent ventilation. High CO2 levels indoors can cause various #health issues including #tiredness, #headaches, #eye #irritation, #dizziness and/or #difficulty #concentrating, so please check your levels inside your house. I borrowed this CO2 monitor as well as an #AQI monitor from my local #library

If you start reading enough about #AQI, you will start to see some rigorously scientificised recipes - this article, for example, suggests ensuring your steak (230g) and asparagus (217g) ingredients are within one standard deviation of their specified weights. https://pmc.ncbi.nlm.nih.gov/articles/PMC8224830/

Smoky smell in the air. Could be nearby woodstoves, or wildfires. Wanted to repost the #AQI resources since there are #Wildfires burning in the US.

Folks, the air quality in Tucson is bad today. If you plan to attend a No Kings protest wear a mask or stay home if you are vulnerable. Check the AQI before you go out. It appears to be mostly particulate matter.

Wondering what people in the Northern Hemisphere are dealing with humidity-wise, indoors.
We heat, and don't humidify, and currently the humidity has dropped to 32% (and falling.) The bathroom sensor read an unbelievable 17% this morning.
I just can't bring myself to add humidity, but dang are eyes, nose, throat and skin pretty unhappy these days. Rising temps will change it this week, I imagine.
Curious what folks are comfortable with.

Went to a public meeting locally held by NCDHHS about new hospital beds being awarded here. Four groups (one is Mission/HCA, boo) then Novant, UNC and Advent. Advent probably the best fit, but just has to be anybody but Mission.
Sat in the back, was one of 2 masks with over 150 people. Had the Aranet and it hit 1453 before I bailed.
Psychosomatic, but have a headache and feel "weird," and damnit this is not happening.

On Monday the #AQI in #Detroit was at least 159. …When AQI levels reach 100–200, "the exposure to the fine particulate matter, the #air #pollution, is similar to smoking a quarter to half a pack a day," Wilgus says.
That exposure takes a toll on a healthy person. But it is particularly harmful for those w/ pre-existing #health issues…. ER visits for #respiratory issues like #asthma & #COPD increase dramatically during #WildfireSmoke events, as much as 2X in some cases.

Hey, #HVAC fans out there. I had looked into HRV/ERV systems several years ago due to very high CO2 levels in this house with only 2 people indoors, but the price, size, and extra ducting seemed prohibitive.
Just took a look around and apparently there are now ductless ERVs which seem like a great idea - basically I really just need an automated window to bring in or vent fresh air during the day.
Has anyone used pairs of these devices? Would love to hear experiences if you have some. Thanks.

Not just human health! The #Toxic Blend of LA’s Urban #WildfireSmoke Will Have Lasting Health Consequences
Los Angeles residents are breathing bits of "cars, metal pipes, plastics."
By Zoya Teirstein, January 22, 2025“These fires are different from previous quote-unquote ‘wildfires,’ because there are so many structures that burned,” said Yifang Zhu, a professor of environmental health sciences at the University of California, Los Angeles. 'Everything in the households got burned — cars, metal pipes, plastics.'
"#Wildfiresmoke is toxic. Burning trees and shrubs produce very fine #particulatematter, known by the shorthand PM 2.5, which burrow deep into the lungs and can even infiltrate the bloodstream, causing cold- and flu-like symptoms in the short term, and heart disease, lung cancer, and other chronic issues over time.
"But the fires that raced through Los Angeles burned thousands of homes, schools, historic buildings, and even medical clinics, blanketing the city in thick smoke. For several days after the first fire started, the city’s air quality index, or #AQI, exceeded 100, the threshold, typically seen during wildfires, at which air becomes unhealthy to breathe for children, the elderly, and those with asthma. In some parts of the city, the AQI reached 500, a number rarely seen and always hazardous for everyone.
"At the moment, air pollution experts know how much smoke fills the air. That’s shown improvement in recent days. But they don’t know what’s in it. 'What are the chemical mixtures in this smoke?' asked Kai Chen, an environmental scientist at the Yale School of Public Health. 'In addition to fine particulate matter, there are potentially other hazardous and #carcinogenic organic compounds — gas pollutants, trace metals, and microplastics.'
"Previous research shows that the spikes in unhealthy air quality seen during such events lead to higher rates of hospitalizations for issues like asthma, and even contribute to heart attacks among those with that chronic disease. A 2024 study on the long-term effects of smoke exposure in California showed that particulate matter from wildfires in the state from 2008 to 2018 contributed to anywhere from 52,000 to 56,000 premature deaths. A health assessment of 148 firefighters who worked the Tubbs Fire, which burned more than 36,000 acres in Northern California in 2017 and destroyed an unusually high number of structures, found elevated levels of the #PFAS known as forever chemicals, #HeavyMetals, and flame retardants in their blood and urine.
"The L.A. County Department of Public Health has formally urged people to stay inside and wear masks to protect themselves from windblown toxic dust and ash. Air quality measurements don’t take these particles into account, which means the air quality index doesn’t reveal the extent of contaminants in the air.
"Zhu and her colleagues have been collecting samples of wildfire smoke in neighborhoods near the fires. It’ll be months before that data is fully analyzed, but Zhu suspects she will find a dangerous mix of chemicals, including, potentially, #asbestos and lead — materials used in many buildings constructed before the 1970s.
"The risk will linger even after the smoke clears. The plumes that wafted over the landscape will deposit chemicals into drinking #water supplies and #contaminate# soil. When rains do come, they’ll wash #ToxicAsh into streams and across the land, said Fernando Rosario-Ortiz, an environmental engineer and interim dean of the University of Colorado Boulder environmental engineering program. 'There’s a lot of manmade materials that are now being combusted. The potential is there for contamination,' he said, noting that little research on how toxic ash and other byproducts of wildfires in urban areas currently exists. 'What we don’t have a lot of information on is what happens now.'
"After the Camp Fire razed Paradise, California, in 2018, water utilities found high levels of volatile organic compounds [#VOCs] in #DrinkingWater. Similar issues have arisen in places like Boulder County, Colorado, where the Marshall Fire destroyed nearly 1,000 structures in 2021, Rosario-Ortiz said, though the presence of a contaminant in a home doesn’t necessarily mean it will be present in high levels in the water. Still, several municipal water agencies in Los Angeles issued preemptive advisories urging residents not to drink tap water in neighborhoods near the Palisades and Eaton fires. It’ll be weeks before they know exactly what’s in the water.
"As wildfires grow ever more intense and encroach upon urban areas, cities and counties must be prepared to monitor the health impacts and respond to them. 'This is the first time I’ve ever even witnessed or heard anything like this,' said Zhu, who raised her daughter in Los Angeles and has lived there for decades, said. 'Even being in the field studying wildfires and air quality impacts, I never imagined that a whole neighborhood, a whole community in Palisades, would burn down.'"
