What are the *specific* reproductive risks of solvent exposure (such
as paint, lacquer, construction glue etc) in women, pre-conception? 
There is a lot of research on how solvent exposure can affect a
developing fetus, but can a mother's exposure actually harm a fetus
before conception? product labels contain the elusive phrase of
"reproductive harm" and I'd like see some specifics.

The answer is complicated by hundreds of solvents that have thousands
of impurities, some of which may be harmful to the fetus even in very
small amounts. My guess is moderate precautions are likely sufficient,
and the fetus will typically repair minor damage with it's immune
system. Water base paint solvents are thought to be less harmful than
oil base paint solvents or acylic base paint solvents. Pregment
mothers are wise to leave locations which have strong oders,
especially the first month of pregnantcy.   Neil

I know you want specifics but here is a rule of thumb...if it is in
the air or on your skin it is in your blood.  Also, fetus' and babies
have very, very undeveloped immune systems.  As soon as you are
talking about xenobiotics (Chemical substances that are foreign to the
biological system. They include naturally occurring compounds, drugs,
environmental agents, carcinogens, insecticides, etc.)you are
involving the DETOX SYSTEM.  When you see frogs with 3 legs you know
they have been exposed to more chemicals than they could get rid of. 
One huge consideration is that one has to look at the TOTAL LOAD. 
This is what mix of chemicals does a mother have in her system from
ALL SOURCES, and HOW DOES THIS MIX OF CHEMICALS BEHAVE IN THE BODY. 
No one has tested (nor could possibly test) all the possible
combinations.  Chemicals are stored in fat tissue.  A MOTHER'S
EXPOSURE BEFORE CONCEPTION is not a "thing of the past."  She now has
chemicals stored in her system (and God help her if she also has
amalgam fillings helping to load her system with mercury).  A mother's
best bet is to get detoxed before getting pregnant.   How to do this? 
Get rid of (as much as possible) all chemicals in your air, food and
water.  But what about the chemicals stuck in the fat?  You would have
to do the research here because there are so many options for
detoxifying the body.  One option is a sauna program delivered by the
ENVIRONMENTAL HEALTH CENTER DALLAS...www.ehcd.com....another is to get
an infrared sauna and follow the instructions in Sherry Rogers book
"Detoxify or Die."  Another thing to do is to keep up your nutrition
so the body has the resources to use its detoxiification system to get
rid of as many toxins as it can instead of storing them in the fat. 
Detoxification takes some research and advice from some experts in the
matter because it is possible to stir up the mix of chemicals and
heavy metals in your system by taking them out of "storage" and then
NOT excreting them.  In which case the toxins run around in your
system doing damage until they find a new place to settle out.  Sherry
Rogers and Dr. Hal Huggins are detox experts, as is a program that
John Travolta helped give to many policeman and firemen who were
harmed by toxins after 9/11.  When you are talking about reproductive
harm you are talking about anything that can go wrong with the
body...cleft lip, club foot, blindness, deafness, low IQ, allergies,
susceptibility to cancer (childhood leukemia is soaring).
