Ron: A few years ago either on Clayart or in the CM question pages the
matter of dirt roads came up. Someone said s/he lived on a dirt road and by
gum and golly that raised more dust than was raised in the studio. The
answer was that the dust on dirt roads is very large particled, and that the
dust in the studio is very fine. The coarse dust might contain lots of
silica but was less likely to injure lungs than the dust in a studio.
Is this correct? And, if so, how does that relate to desert dust....Do
camels and Bedouins get silicosis?

"Do camels and Bedouins get silicosis?"
Indeed Lili,
Sahara tribe members develop a benign form of lung silicosis.
This is described in french books on Occupational Health.

Hi Lili,
Dust comes in all sizes - road dust is a combination of both course and
fine - it's only a matter of percent of each. What will be more important
is how much of that dust is silica and what part of that silica is 0.5 to
0.7 microns - that is the silica that gets trapped in the lungs.
Then there is the dust that gets into the car and you carry around with you
- and gets air bourn again every time you go anywhere.
If you live or work in any kind of dust you exposure to silica is higher -
so you need to pay more attention to studio air.
I believe the comment was about dusty roads so you did not have to worry
about dust in the studio - I say just the opposite - including anyone who
lives in a desert.
This is not to say we are all going to get silicosis if we don't work and
live in clean air - the question is - what are we going to get and will it
be a factor in limiting what we can and can't do in our old age. Some
gambles are worth the risk but what is it about working in silica dust that
is worth it?

Hello Ron,
" I believe

Sorry to disagree:
Silicosis in the Sahara,
cases of simple silicosis have been described among members of
tribes(Bedouins) living in the Sahara desert due to sand storms.
Micro-nodular lesions are present on chest X-rays. They do not seem to
develop classical silicosis, this simple form of pneumoconiosis does not
seem to cause clinical symptoms/signs. ( Encyclopédie Médico-Chirurgicale,
Toxicologie, Pathologie Professionelle, Paris, 1999)
This encyclopedia is written and kept updated by the best french specialists
in Epidemiology, Toxicology, Occupational & Environmental Medicine,etc.
For decades large parts of the Sahara was under french rule.
I presume these specialists know what they are talking about.

I still say - those who live in dusty places should be more concerned about
studio dust.
It is also true that crushed silica - what we use mostly - is sharp -
cutting and is more dangerous than rounded - like beach or wind blown sand
because the sharp bits are worn off - still - it is there and not the best
thing for our lungs.
Some times experts know what is going on and we still suffer the
consequences - shall we start a list about it? Should we start with DDT or
perhaps lead in gasoline?
Some times the experts are working for those who want to minimize problems
- or must to keep their jobs - we can still think for ourselves and make
the choices we think are in our best interest - and we don't have to be
right every time - it is a conservative philosophy but you don't have to be
one to have it.
