I would be hesitant to identify things based on what they smell like.
Some air fresheners smell like mothballs to me.
Might be something you should get more specific sampling done.

This may sound strange, but some of the men's urinal deodorant blocks have similar chemicals.

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,
