gibsonj64@yahoo.com - 21 May 2008 18:58 GMT
A new study from the Project on Emerging Nanotechnologies in
Washington, D.C. has found that long threads of carbon nanotubes may
have a similar toxic effect as asbestos, according to an Associated
Press report...

Tiny fibres used in tennis racquets, bicycle frames and some
electronic equipment could be as dangerous to inhale as asbestos,
experts warned on Tuesday. A new study has linked the fibres, carbon
nanotubes, with mesothelioma, a cancer of the lung lining...

 Any fibers that, like asbestos, are small enough to cut through a cell
(and it's dna) will produce the same problem.

Wrong. Smoking increases the risk, but it isnt zero in non smokers.

Al, you and I both know that in general researchers will never publish
when the result of their findings compromise the interests of their
funding sources.

Please, lts not corrupt the minds of the kiddies into believing that
people in science are more altruistic than anyone else having a family
to feed.

My take on this mesothelioma thing is that is is primarily being
promoted by attorneys who would otherwise be out chasing ambulences. I
could be wrong on this, but it's unlikely.

Al, to be perfectly honest with you, I've smoked a pack of Camels each
day since I was 16. being taught to smoke by the guys returning home
from WWII and Korea -- Guys that you made a lot of noise intentionally
when you approached them from behind. (I assume that you know why this
was done.) So, based on this you know my age.

During my youth, I peeled tons of asbestos off of insulated coal
heaters when in the time when they were being replaced by automatic
gas or oil fired systems. Quite often, the air in the spaces were we
worked were filled with asbestos dust so thich that sometimes it was
hard to see across the room.  During those years we didn't wear dust
masks, and even protective eye wear was rare.  We simply choked and
complained in order to make enough money to move on to better things.

Then too, the better things that I went on to involved constant
exposure to nuclear radiation and toxic chemicals. To hear the fear
mongers speak, I should have been dead 30 years ago, but here I am
still posting. Possible the Neutron flux that I encounter earlier in
lif caused premature cataracts in both of my eyes, which have since
been replaced with plastic lenses, and the diventiculitus that
required the remove\al of 12" of colon could have been a result of
that early radiation exposure, or simply as a result of eating too
many peanuts.

Al, we live in an age where everyone is trying to fix the blame of an
adversity that they encounter or some external influence. Today, this
is where attorneys get their payday, and my partner in crime is one of
them. Litigation pays big time, if you win.

Al, I'm now 70, and based upon family history, expect to live until
age 76, at which point there will likely nothing more to live for. The
eldest member of our family lived to be 87, and was an incredible
alcoholic -- He drank more than one bottle of Wild Turkey each day. He
was also the CEO of a major power company at the time of his death. He
was also a SOB in my opinion, who never even once bought me lunch when
I was eating "lumberjack floats" during my senior year at Drexel.

Pity about the research which is funded by govt and so
there are no interests to compromise on questions like that.

Hordes of them arent funded by the industry they are doing the research in.

Nope, not when that sort of research has been going on for many years now, and
most of the research was done by those with no financial interest in the result.

Irrelevant to whether mesothelioma risk is increased for smokers exposed to asbestos.

And its completely trivial to show using rigorous scientific research that
the risk of mesothelioma is much greater amoungst those who did that.

No one was ever stupid enough to claim that the risk was 100%

We also live in an age where heaps of environmental risks
have been properly quantified using decent rigorous science.

And plenty of fools keep proclaiming that stuff like smoking has no health downsides too,
without a shred of scientific research to substantiate their stupid pig ignorant claims.

Only in the stupid US system.

You've obviously had nothing to 'live' for for decades.

Irrelevant to what increases the risk of mesothelioma.

 And that's why Galileo chose to be labeled a heritic and imprisoned for
life rather than refusing to publish his findings on the sun centered solar
system.

WARNING! INHALING TENNIS RAQUETS, BICYCLES, AND ELECTRONICS CAN BE
HAZARDOUS TO YOUR HEALTH!

The most widespread mutagen is a NORM - Carbon-14.

It is about 1 ppb of all naturally occurring carbon in the atmosphere,
and therefore in living plants, food, animal feed, animals, and human
beings.  Yes, YOU are radioactive!

Your body has a naturally higher level of radioactivity than the
coolant water from a nuclear power plant.

Unlike uranium, thorium, and other radioactive bogeymen, which cause
mutations in a manner similar to shooting rifle bullets at a house
with hopes of cutting the power mains (less than a 1% chance),
carbon-14 attacks DNA at point-blank range.  The body concentrates
carbon from food into its protein and its DNA, and when a carbon atom
in a DNA molecule undergoes radioactive decay, the chance it will
mutate the DNA is 100%.

Of course, if you really WANT something trivial to fret about, there
are plenty of likely candidates out there, and plenty of hysterical
environmentalists willing to "educate" you about them.

No!:

The body content of 14C for a 70 kg man would be about 3.08 kBq while
for a 70 kg man the amount of 40K will be about 4.26 kBq!

Since essentially all sources of human food are derived from plants,
the carbon that comprises our bodies contains carbon-14 at the same
concentration as the atmosphere. The beta-decays from this internal
radiocarbon contribute approx 1 mrem/year (.01 mSv /year) to each
person's dose of ionizing radiation.[14] This is small compared to the
doses from potassium-40 (0.39 mSv/year) and radon (which vary)

Given its concentration and decay rate = it is a rifle bullet
probability!

Well, there are many dangers in the Natural Environment!  But why just
place more potential dangers out there that the living system has not
evolved with without first knowing what their effects will be?

Virtually ANY irritant has the potential to cause cancer.

OTOH, despite its bad rep, asbestos has ONLY been proven to cause problems
in industrial environments, NOT in normal domestic use.

Nope, most obviously with hayfever and allergys.

Wrong, particularly where there was extensive use of
asbestos in houses and that got exposed by renovations.

It's been known for some time that Buckytubes have highlyoxidizing
properties which tends to be cancerous when embedded in tissues.

Big bummer.
