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.

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.
