   Are you doing or planning research related to control (removal) or 
generation of TRACE CONTAMINANTS in air or water?  [Examples: removal by 
photocatalytic oxidation, removal by adsorption, removal by reactive 
plasma, generation by algae, etc.]  If so, I would like to hear from 
you.  I am beginning studies of trace contaminant control in closed and 
near-closed loop air and water systems for long-duration manned space 
missions, and would like to learn what others are doing in related 
areas.  Through this letter I hope to make a few contacts and perhaps 
initiate some dialogue/discussion concerning various aspects of trace 
contaminant control: issues, theories, experiments, technologies, etc.

   Please respond with a brief summary of your work, perhaps a short 
bibliography, and how I might reach you. Electronic or postal mail is 
fine.  Also, if you have comments or suggestions I'd appreciate hearing 
from you.  Finally, please pass this letter on to anyone who might be 
interested but may not otherwise see it.  Thank you for your interest.

   I would particularly encourage you to respond if you are studying 
adsorption of trace components, as this is an area upon which I am 
focusing at present.
