amines from a recycler


We have an ETOH/Xylene/Formalin recycler in our lab and one of our technicians says the paraffin-embedded blocks have a fishy odor.  On more than one occasion, when this technician noticed a stinging sensation in their eyes and lungs by the time they finished cutting blocks for the morning, and tingling in the fingers by the time they finished cover slipping the slides later in the day.  We are concerned that this is related to the production of amines and thus far, the addition of acetic acid to neutralize the amines has not corrected the problem.  Has anyone else had similar experiences?
