The two other responses seen useful. I would recheck to confirm that the entire building has shingle pass air. Usually only the labs have single pass air. You should also check to see that there is no re-entrainment of exhaust air. Has there been any recent maintenance on the HVAC system or has there been any significant change in the nature of the research that is being conducted? Also, check to make sure that all drain traps are full of water (sometimes sewer gases can cause problems.). Finally consult with others on the campus to make sure that the problem is not confined to only the one building. It could be with the hot summer and possible elevated levels of ozone and other oxidizers in the atmosphere that these pollutants are causing the problems. Interesting problem. Good luck and let us know how it turns out.

We have researchers whose latex gloves, rubber bands and other latex-containing articles degrade at an alarming rate. This is annoying. Lately, a photographer in this building has found her images degrading as well. This is now causing consternation amongst building occupants. All the obvious have been checked - it is a laboratory building with one-pass air and the degradation is not localized to a single floor or lab. Ideas? Don't be shy about suggesting the outrageous.
