Re: What's that black dust in monitors?

A layer of air 4 miles thick

You dont get that 'flowing out of some thunderstorms'
with 1 PPM NO2 has light going through as much NO2
as it would going through a 1/4-inch layer of pure NO2,

Pity it doesnt end up brown at all at that concentration.
which is quite brown.

Yes, but not at 1 PPM it aint, even thru 4 miles of it.
I have seen an ampoule of the stuff before.

Irrelevant to what air with 1 PPM looks like.
A 1 inch thick layer of pure NO2 (some of it becomes N204 when
that concentrated, a molecule of which is basicaly just two NO2
molecules stuck together more than being a different compound)

Thats utterly mangled too.
is a rather dark brown, although still lighter than a Budweiser bottle.

And at 1 PPM it aint even visible.
The stuff looks like bromine vapor.

And at 1 PPM it aint even visible.
You can make visible quantities of nitrogen dioxide
in a small glass jar if you put in that jar a spark gap
with a capacitor of about a nanofarad across it and
power the spark gap with a neon sign transformer.

Taint relevant to whether 1 PPM is visible. It aint.
You may need to adjust the spark gap or try a larger capacitor
(with power off!) if instead of a loud bright series of sparks you
get an arc. Beware that a neon sign transformer with a capacitor
across its secondary can resonate and the voltage may get high
enough to cause destructive sparking in the transformer unless
the spark gap is short enough to limit the voltage to a value
safe for the transformer's insulation.

All completely irrelevant to the visibility of 1 PPM.
Unhealthful air quality based on average concentration of the worst
hour is .3 PPM of NOx, and that is mostly NO2, and that seems like
enough to be visibly brownish in a layer just a few miles thick.

Nope, fraid not.
And how about ones in not-so-bad tune that make finer soot?

You dont see that rising either.
I see enough blackish smoke from diesel
trucks rising and flowing with air currents.

Dont believe it.
Sometimes it looks bluish when illuminated by sunlight,
so some of that soot has to be of particles of size
around a wavelength or somewhat smaller,

Thats just smoke, not the jet black soot being discussed.
and particles that size don't fall out of the
air faster than the gray stuff from wood fires.

Pity it aint the jet black soot being discussed.

Depends entirely on the specific pollution you are talking
about. Gasoline engines dont normally produce anything
like the same level of that black stuff being discussed
there as a very badly setup diesel engine.

Reams of your puerile shit flushed where it belongs.

More immature baby bullshit from the twit that couldn't approach
light speed with a light speed rail gun, much less exceed it with the
"worldly" bullshit you bring to the table of life.

Again, dipshit... They are NOT "badly set up". They are set up rich
for a reason. Get a clue. And NO, they do not pollute more.

YOU were badly setup, however.

You seem to have this thing for plastics outgassing.

Sorry to burst your bubble but plastics that are used for monitor
housings do not outgas black particulate.

"Outgas black particulate" are your own oxymoronic words..
The "plastics" used for the FBT shell are thermoset plastics and do
not outgas. The potting material for FBTs does not outgas. IC chips
and transistor are NOT packaged in plastic, they are encased in EPOXY,
and the type used only "outgasses" at very high temperatures for
exceeding those of the interior of a monitor shell.

Conclusion: Plastic, and plastic outgassing is NOT the source.

All plastics, and even metals, outgas to some degree varying with
temperatures. Asian plastics and manufactured products in
particular as used for much consumer electronics, contain a very
high level of recycled low quality plastic, and leftover
production chemicals. Other causes include:

The source is externally attracted airborne particulate... PERIOD.

Glad you sorted all that out finally..

You sure as hell do; lightning is one source of the stuff!

Yes, but not at 1 PPM it aint, even thru 4 miles of it.

Same amount of NO2 that light has to pass through!
Irrelevant to what air with 1 PPM looks like.

No, it's your knowledge of chemistry that is mangled.
And at 1 PPM it aint even visible.

Until you look through a couple miles of it.

"Brown Cloud" air pollution is nitrogen dioxide or nitrogen dioxide plus
carbon particles fine enough to make things seen through the cloud look
brownish due to scattering preferentially of blue light.

One source saying nitrogen dioxide plus fine carbon particles:
http://phoenix.about.com/library/weekly/uc051601a.htm

Another source saying nitrogen dioxide is responsible for "brown cloud"
urban air pollution:
http://phoenix.about.com/library/weekly/uc051601a.htm

Just the first two hits of a Google search of "brown cloud" "nitrogen
dioxide"! A few other hits whose summaries reported by Google appear to
support nitrogen dioxide, whether alone or with really fine carbon
particles, making air look brownish:

Are you calling me a liar? When it is visible, the finer stuff easily
visibly rises!
Dont believe it.

Looks like you haven't paid attention to a few on the road!
Thats just smoke, not the jet black soot being discussed.

So you say diesel trucks produce smoke other than soot and other than
the gray "oil burning" stuff? And what else has a "gray-transparent" look
when seen through and when finer, has a "diluted-milk-grayish-blue" but
darker when illuminated by sunlight?

I can make soot fine enough to look bluish when illuminated by a bright
flashlight by running a propane torch with the air intake holes blocked.
I just tried that! Are you going to say that propane can make ash or tar
particles?
Pity it aint the jet black soot being discussed.

"Brown Cloud" air pollution is nitrogen dioxide or nitrogen dioxide
Wrong.

plus carbon particles fine enough to make things seen through

Particles of many kinds, actually. Doesnt have to be carbon.

Its that that produces the spectacular red sunsets with major fires.
One source saying nitrogen dioxide plus fine carbon particles:
http://phoenix.about.com/library/weekly/uc051601a.htm

Its wrong. Basic physics. Steve clearly aint gotta clue and his
'credentials' are complete duds as far as physics is concerned.

Nope, just one actually. And plenty of pig ignorant shit turns up on the web.
A few other hits whose summaries reported by Google
appear to support nitrogen dioxide, whether alone or
with really fine carbon particles, making air look brownish:

We'll see.

The first para of that says

Extremely small particles are the principal cause of the brown cloud.
These tiny particles, too small to be seen without a microscope, are
measured in microns, with one micron equal to about one-seventieth
(1/70) of the diameter of a human hair. Particulate matter less than
2.5 microns, often referred to as PM2.5, is a significant cause of haze.
Each particle, about the size of a single grain of flour, can float in the
atmosphere for days, behaving much like a gas. Over half of the
PM2.5 in Phoenix is caused by the burning of gasoline and diesel fuel
in vehicles (sometimes referred to as on-road mobile sources) and in
off-road mobile sources, such as construction equipment like loaders
and bulldozers, locomotives, lawn mowers, leaf blowers, and other
devices that emit air pollution as they move1. PM2.5 particles containing
carbon, like soot from tail pipes, are particularly effective in reducing
visibility, because they both scatter and absorb light.

Which is exactly what I said, using a lot more words.

Doesnt say that the brown is primarily NOx

Doesnt say that the brown is primarily NOx

Pure political bullshit.

3. Is it a brown cloud day? A brown cloud appears to envelop
the scene but quickly thins out at higher elevations. Look at
the particle and black carbon levels -- they are usually high.
Ozone will be low and relative humidity may vary.

Doesnt say a damned thing about NOx
being the cause of a visible brown haze.

Try again.
Are you calling me a liar?

Nope, you just havent got a clue about the basics.
Those dont rise like say smoke from a fire does.
When it is visible, the finer stuff easily visibly rises!

Not far. THATS what matters.
Looks like you haven't paid attention to a few on the road!

Looks like you aint gotta clue about what's being
discussed, whether that stuff rises that much.
So you say diesel trucks produce smoke other than soot

A properly setup diesel engine does just that. Its only the badly
setup trucks that generate high levels of the jet black soot you
see inside monitors adjacent to the FBT, and as Ken pointed
out, you STILL get that inside monitors, even when there are
bugger all diesel trucks in use at all, let alone many setup
that badly. So it cant be coming from diesel trucks.

Basic logic.
and other than the gray "oil burning" stuff? And what
else has a "gray-transparent" look when seen through
and when finer, has a "diluted-milk-grayish-blue" but
darker when illuminated by sunlight?

What was being discussed was how many diesel trucks produce
much JET BLACK SOOT. You claimed that that somehow ends
up in monitors. You cant explain why you STILL get that jet black
soot in monitors even when there aint no diesel trucks in use at
all, SO IT CANT BE COMING FROM THEM.

Basic logic.
I can make soot fine enough to look bluish when illuminated by a bright
flashlight by running a propane torch with the air intake holes blocked.

Got SFA to do with whether the jet black soot you can see with
badly setup diesel engines is what ends up inside monitors.
I just tried that! Are you going to say that
propane can make ash or tar particles?

Nope. It doesnt produce JET BLACK SOOT normally
either unless you completely stuff up the gas to air mixture.

And that doesnt happen enough for it to be the
source of the jet black soot we see inside monitors.

I guess visible black soot and sickening smell don't count as pollution.
It's probably healthy for us.

I guess the reason is the exhaust is at the back.

If the exhaust were to be in the middle of the steering wheel, I guess
cars would be much cleaner.

From what I've read recently, this stuff is far worse than what
is expelled by a typical gasoline engine, yet the EPA thinks it's
peachy. Tighter regulations on diesel engines is coming.

You don't get it. Just because you *cannot* see what gasoline
engines produce, doesn't make it "less than a diesel". Doh!
I grew up around fresh turned eastern US clay and earth from new
construction, AND the smell of the diesel machinery. I love it.
Particularly when compared to the fucking rotten egg smell that the
sulfur in gasoline produces. You are clueless. Until your lame ass
sits in traffic on an open machine such as a bicycle or motorcycle,
I'd say that you don't know what the **** you are spewing about.
