Look at your deodorant while putting it on your armpit tomorrow morning.

Look at your ozone-producing ionizing air cleaner and photocopier when you go into the office.

They combine to produce
Ultra Fine Particles that you inhale, and then they migrate to every organ.

🧵 Perfume spray.
Man spraying on deodorant.
Right off the bat? The non-ozone producing #corsirosenthalbox, does remove UFPs AND volatile organic compounds (VOCs).

So should any HEPA.

BUT.

You will inhale them because your body has a thermal plume from your body.

Sorry for the long setup. You need to read this,
but I did not want to be click-baity.

So, deodorant, hand lotion, body spray, perfume, spray shampoo - and most likely anything that has a fragrance produces VOCs.

"Monoterpenes, in particular, are known to react with ozone inside, forming secondary organic aerosols (SOAs)." Personal hygiene products, including roll-on deodorant, hand lotion, body spray, perfume and spray shampoo, contain an amalgamation of over 200 volatile organic compounds (VOCs), which then react with ozone in the air to form other potentially dangerous chemicals, according to a new paper in the journal Environmental Science & Technology Letters.
Personal care products contain a large cocktail of VOCs, including monoterpenes, acetaldehyde, siloxanes, alcohols, and alkanes. perfume spraying Stock image of a person spraying perfume. Personal care products like perfume, hair spray and hand lotion can release volatile chemicals that may react with ozone to other compounds.
Your fragrant ________ (insert Old Spice, Axe Body Spray, No. 5 Chanel, etc,), produces VOCs. They hit ozone and react. Turn into aerosols.

That clump up into UFPs. And your thermal body plume carries up for you to breathe them in.

Size illustration below. When using the PCPs in the presence of indoor ozone, these reactive VOCs underwent oxidation reactions to form a variety of gas-phase oxidized vapors and led to rapid new particle formation (NPF) events with particle growth rates up to ten times higher than outdoor atmospheric NPF events," the researchers wrote.

Is it me, Mr. Clean Air, just freaking out?

You judge - here are the scientists.

It IS difficult to hear that.

But it has to hit ozone, right? Where does THAT come from? "I know this is difficult to hear, but we're going to have to reduce our reliance on these products, or if possible, replace them with more natural alternatives that contain fragrant compounds with low chemical reactivity," Licina said. "Another helpful measure would be to raise awareness of these issues among medical professionals and staff working with vulnerable groups, such as children and the elderly."
Some definitely comes from outside. But that is short-lived, albeit, if it's always coming in ?

But ionizing air cleaners produce a ton of ozone - whether in-duct or portable air cleaners.

I know there will be a ton of questions. I think
. ncbi.nlm.nih.gov/pmc/articles/P…Highlighting ionizing air cleaners because they produce ozone.
The average outdoor ozone concentration in a day tended to be low in the morning and at night and high at noon. During the year, it tended to be high in spring and summer and low in autumn and winter. The half-life was usually between 7 and 10 min for ozone indoors, which has a relationship with surface removal rate and air exchange rate. Fadeyi [19] proposed that the contribution of ozone air purification equipment with a high ozone emission rate to indoor concentration could easily exceed that of outdoor ozone.
the most common ones will be....

How to tell if my product has monoterpenes? If it has a fragrance, it probably does.

How to tell how much ozone is there?

They sell Ozone Detectors on Amazon.

But, cheap may not be best.

Here's a good article, but

How do we know TB is airborne?

71 guinea pigs gave their lives between 1956 and 1958 in the eponymous study by Riley et al, getting TB air piped in from some TB patients, to prove TB is airborne.

Influenza is kind of airborne per most doctors. But kind of not.

So....

We need some volunteers.

Will horses be those volunteers that finally lay it all out?

Yes - but none of them lost their lives.

Air samplers were deployed and tracked horses inoculated with Equine influenza virus (EIV).

From the very first day post inoculation (dpi), until the Image
12th day, EIV was found in the air, in this new study.

With no horses, or guinea pigs, hurt in the process.



But sure, influenza's not airborne - if you are the USDA, right, @nirav_maine?

Of course, yet another new study points an accusatorysciencedirect.com/science/articl…

Thank you @BarryHunt008 for flagging this.

@ThailandMedicaX, retweeted by some because of their controversial takes (ahem, their lies?), is saying that FAR-UVC is dangerous because somehow the light will get into the lungs.

Lol.

They are just apparent supplement grifters.

Hmm. I helped defend Nukit against charges of Image

You've heard of "The Three Problem." - great book, and excellent Netflix series.

If you want to be avoid catching Covid, you probably have "The Empty Room" situation in the back of your mind.

How long after a room had people in it, can you safely demask?

Measles was thought to be airborne after a child caught measles an hour after the infected child left the same office.

.

Interestingly, you can see the reluctance in blue below to call measles airborne. Much like the WHO with @mvankerkhove researchgate.net/publication/19…In February 1981, a measles outbreak occurred in a pediatric practice in DeKalb County, GA. The source case, a 12-year-old boy vaccinated against measles at 11 1/2 months of age, was in the office for one hour on the second day of rash, primarily in a single examining room. On examination, he was noted to be coughing vigorously. Seven secondary cases of measles occurred due to exposure in the office. Four children had transient contact with the source patient as he entered or exited through the waiting room; only one of the four had face-to-face contact within 1 m of the source patient. The...
which spent millions to rebrand SARS2 as "through the air" rather than airborne.

It is an inconvenient truth that then leads us to the study showing an #EmptyRoom SARS2 infection at 1 hour and 43 minutes, and FOUR HOURS and FORTY-FIVE MINUTES.

In this study, it comes with Experimental evidence suggests that SARS-CoV-2 remains viable within aerosols with a half-life of approximately 1-3 hours, though changes in aerosol microenvironment may shorten viability to minutes. However, it remains unclear how long airborne SARS-CoV-2 can transmit infection. Whole genome sequencing of nasopharyngeal samples obtained from patients on an outbreak unit suggested in-room transmission of the delta variant, AY3 lineage, of SARS-CoV-2 to two patients admitted 1 hour, 43 minutes and 4 hours, 45 minutes after discharge of an asymptomatic infected patient. These findings suggest...

Mum's the word - if @SecKennedy is Mum.

You see, I have been a VERY FOCAL CDC critic. But you can't criticize without listening.

And I have been noticing that that the CDC has been very, very quiet.

NPR noticed as well. Image
This is crazy. Image
Yes, the @CDCgov has been deathly quiet.

90 times last year, versus 4 this year.

This is not MAHA.

This is MASA - Make America Silent Again.

And as one of the CDC's most focal critics? We NEED them to be sharing Public Health information. Image

Fit factor of 250- 4000 versus the normal 100-200 for an N95? Where do I sign up?

Oops, that's here. With me. Starting a build with an Ebay'd Bullard EVA PAPR's filter - and some DIY loving goodness of a heat gun and PVC pipes.

The benefit of this build will be the over 10
hour run-time of the massive battery on the PAPR.
Got a long dental appointment? This will be the answer.
