Form what you have described, it sounds like you have been subjected
to zinc fumes. Other symptoms include throat dryness, coughing,
weakness, general aches, nausea, vomiting, chills and fever. I don't
think it results in any permanent damage to the body like lead does,
unless the case is very severe. Zinc is an essential element for the
body. Obviously, the fumes should be avoided & I think that you will
find that the contractors have an obligation to extract the fumes
from the work area, not distribute them around your building.

Subject: Dataloggers

Re Anne Pat Smith's query on the relative merits of dataloggers vs.
hygrothermographs.  I have been using dataloggers for about 6 years
and found them to be very useful for monitoring areas and buildings
where frequent servicing is difficult.  While a datalogger is not as
accurate as a properly calibrated and positioned hygrothermograph,
most can go a year or more between calibrations, can be happily left
alone for long periods, provide data that can be easily manipulated
to produce a variety of graphs and reports, and tucked away in
awkward spaces.  I would see them as a good choice for a "remote
storage" location.
