[NHCOLL-L:4586] Re: HgCl2

Patricia and all-

Some government agency, city, county, state, or fed,
with a local office will have a sniffer, an instrument that
can detect very low levels of mercury vapor.  They will
send a technician to check your stuff.  I had it done to
check a carpet at home where a thermometer broke.
They did not charge me. I would try calling city hall first.
