Interesting.. I'm ex-IBM and had the exact "moldy orange" experience listed below here at NC State. Only different is the desk was in a complex lab area. These can certainly be tough to pinpoint. Some of these can be quite a task to pinpoint. Dry traps, wet insulation, etc ... A number of years ago we blew theatrical smoke into the waste line vent pipe on the roof of our chemistry building after a frustrating run of fugitive odors and had facilities personnel moving through labs in the building to spot emissions. We found more that one area with compromised waste drain plumbing.

Could there be some cultures of such in there? Certainly, many "moldy" odors are actually from biological organisms. Could it in fact be that "dirty socks" are actually dirty socks (as in someone's overlooked gym bag)? I'm reminded of a case at a major IBM facility a friend of mine investigated some years ago of "sick building syndrome" in an office area that turned out to be a "lost" mouldy orange buried beneath paperwork in a worker's lower desk drawer (after an expensive IH evaluation of multiple worker odor complaints had already been done). Just a thought. Alan Alan H. Hall, M.D. Medical Toxicologist.

Dry traps are usually a good one to start with. If you (and your facilities and research staff) have exhausted all possibilities there is also something called “dirty sock syndrome”. Google it and you will see many reference and discussions. Here is a link with an explanation. We recently had an issue that people described as dirty socks, sewer gas, etc. After several months found the odor by reviewing the floor plan of the building and following the pipes in the walls. We found a couple of uncapped pipes that were no longer in use. Good luck, Patty Patty Olinger, RBP Director EHSO Emory University 1762 Clifton Rd., Suite 1200 M.S. 0940-001-1AB Atlanta, GA 30322 404-727-5690 office 404-727-9778 fax How are we doing? Please take a minute to complete our survey: TEAMWORK...Our Path to Excellence "Harrington, Rachel" wrote: We have a strong “dirty socks” odor present in one of our micro labs. It’s a pretty typical lab using media and cultures, etc. and we are systematically removing everything and deconning but this odor is persisting. I know I have smelt this chemical before, maybe back in my undergraduate days, but it is really a sickening odor. Any ideas? Any help is greatly appreciated. Thank you! Rachel E.
