Subject: Question on tars and nicotines in tobacco plants

Hello

   I am a student in a physical science class at Mt. Shasta High School
and am currently working on a science project that deals with determining
the % tars and nicotines found in cigar, pipe and chew tobacco.  Our
school library has limited reference material that I could access.  I also
called the tobacco companies and did not even get a response.  
   Perhaps you know something about tars and nicotines found in tobacco
plants that you could share with me?.  Ideally it would be nice to be able
to put my hands on the actual % data that describes the amount of tars and
nicotines in each type.  
   My plan to test the results is to draw smoke from the burning tobacco
source through pre-weighed cotton balls and then by measuring the
difference in the cotton ball weight compared to the actual tobacco that
burned, I should be able to calculate the % numbers my teacher demands. 
He is mean!  Does this procedure sound OK to you?  If there are holes in
this procedure perhaps you can suggest modifications. 

I appreciate any help that you can provide.  Thank you.  Hillary

David:

Aside from the classic papers (e.g. Karl Niklas' series in the early and 
mid-1980s) and books (e.g. IBP's aerobiology tome from 1979 [?]), you might 
find some people to talk to on AEROBIOL-L (a listserver run from here at 
the University of Guelph by Franco Di-Giovanni).  I can send you the 
subscription instructions by e-mail (or to anyone else reading this post).

I don't know if anyone at Cornell is still working on the wind 
pollination topic since Karl Niklas went onto structural mechanics and 
allometry (and editing the Am J. Bot); you might trying contacting Karl 
directly.

Cheers,

Could someone out there point me towards researchers, institutions where
biophysical modelling of wind pollination is being carried out?

						thanks, David

why am I not surprised

Why not try ASH (Action on Smoking and Health).  They do have a web page, which
I do not immediately have available.  if you want it send me a note.

They have massive amounts of the sort of data you are looking for.
