PM10

They're also released by a lot of personal care products, scented candles, incense sticks, room fragrances, whether that's plug-in or using essential oils, and then you also get the reaction of chemicals with each other to form new particles or chemicals when they're in the air around us.

And then we're also talking about two kinds of small particle called PM2.5 and PM10, and they're absolutely tiny particles that can get really quite deeply into our lungs.

They're, um, getting as far as the blood and, in some cases, into our brains.

And the big question is what that then does to our health.

And the PM2.5 and the PM10, where are those ones coming from? Are they from our cleaning products, or are they kind of entering the air from elsewhere?

Both.

[laughs] Um, so PM2.5 and PM10 are kind of, uh, best known, as it were, as, um, things which come from pollution that we're more familiar with, like vehicle exhaust pollution or pollution from industry and factories.

Um, but actually, they come from lots and lots of different things.

And again, th- they're simply lying, and we know this.

I've been in high-level EPA meetings in Sacramento, five top California EPA official- officials, meeting arranged by congressional rep, told, the entire system is rigged, told to my face that they test for combustion particulates only, generally PM10, which is a boulder compared to a nanoparticle, so the rest goes completely unreported and completely under the radar.

Completely rigged system because they cannot afford people to wake up to what's happening in our skies.

Dane Wigington, if you'd like to chat with him, that would be great.

2.5 refers to the size, 2.5 microns.

There's also PM10, that's 10 microns.

There's also ultrafine particles, PM1 or below.

And the problem with those really small ones is that you not only inhale them, but they can go through the alveoli into your blood systemically.

So it's those very small particles that cause a lot of our problems.

We have PM10.

Is that correct? PM10.

Larger but still dangerous.

That's

larger, yeah.

PM10, the thing to keep about particles in the air, it's actually a continuum.

So PM2.5 is a subset of PM10.

Why, Professor Tong, is somebody feeling, when there is transboundary haze, this kind of itchy, watery feeling in their eye?

Well, there's a lot of research on the components of haze, right? I mean, you could have the PM2.5, the PM10, you could have gases like sulfur dioxide, nitrogen dioxide, you have carbon monoxide, right? So all these pollutants, so to speak, can actually damage the front of the eye by destroying the barrier.

So imagine if you and I are both guardsmen of this delicate tissue and we linked our arms together, so what the pm 2.5 does is it destroys it it has to burst through the space between us so it has to destroy our arms or injure our arms in order to get through right so that's what's happening so if the thing is damaged then you actually opens the channel for more PM2.5 and more particles to get between us.

That's how the alarm system works.

They saw a 25% reduction in nitrogen dioxide, NO2.

And a 17% drop in PM10 particles, I think.

Exactly, PM10.

Those microscopic pieces of soot that cause respiratory disease.

They plummeted.
