Environmental effect on Sjorgen's?

Greetings,
I have been experiencing symptoms of Sjogren's Syndrome from shortly after our office relocated.  Dry skin, rash, horrible mouth burning and soreness, thrush, insatiable thirst, bleeding sinuses and such.  About half of my co-workers have reported similar problems since we moved last year, particularly with mouth problems.  One of these co-workers was just diagnosed with Sjogren's and I am concerned that I have it, too.  Being a male with no hx of RA makes this a longshot, but my symptoms are significant.  I have an appointment with an RA doc to be evaluated.  

I am convinced that these symptoms are being caused by my workplace environment, an old factory which is built at the ocean's edge and currently has manufacturing companies as tenants.   There is water in the basement and there are hazardous chemicals and resins down the hall from my office. Moreover, my symptoms (with some delay) worsen and at least partially resolve based on whether I'm at work or not and whether the heat or air conditioning is running on high or not.  This pattern is also true for my co-workers.  Accordingly, I predicted the recent exacerbation of symptoms I am currently experiencing since the heat has been turned back on.  It's hard to believe that this is all coincidental, but I cannot find a direct link between environmental irritants and Sjogren's Syndrome or its symptoms.  Is there any validation of this relationship?  

Any help you can offer would be genuinely appreciated.
