After doing about two decades of spill cleanup on active Navy ships, I would NEVER trust a nose to identify, even a tentative semi-quantitative I-think-it-smells-like try-ethyl merman.  As with other responses, physically hunt for source(s) and / collect some samples.

Subject: [DCHAS-L] odor question


Greetings all,

We are investigating an Indoor Air Quality issue in an infrequently used faculty office which is full of books, papers, a computer server, etc.  The odor is mothballs, and we cannot locate the source.  (Believe me, we've been trying!)  We've done a lot of work already, investigating, ruling things out, etc.  My question to this list is:

Has anyone had an odor issue where a mothball odor was caused by something other than mothballs?

I am aware that the chemical which causes the distinctive odor in mothballs is either naphthalene (older products) or 1,4-Dichlorobenzene (newer products).  This faculty member is not doing any chemistry but rather investigates materials and their mechanical properties.

All thoughts are appreciated.

Thank you,
