EPA Edison, NJ laboratory, mid-October 2001.

A van was contaminated with mercury vapor using a large (2'x3') polyethylene tray lined with carpeting. A measured weight of mercury, of controlled droplet size, was sprinkled on the carpet. Initial mercury vapor levels were measured with a Russian Lumex 915 mercury vapor analyzer. The levels were above the instrument's range and so a German Mercury Instruments VM-3000 having a lower sensitivity but a higher range was substituted. This simulation was concluded and the levels were continuously high. It took some weeks for the residual mercury absorbed on to surfaces and absorbed into porous upholstery etc. to dissipate once the plastic tray was removed.

EPA Edison, NJ laboratory, mid-October 2001.

A simulation of a mercury-contaminated dwelling being prepared in a 30'x10'x8' office trailer. The mercury contamination is to be effected in a similar manner as in the van. The trailer is now (mid-December) in the final stages of being outfitted with a sofa and other furnishings and curtains. The scientist in charge suspects that the mercury vapor levels will be very high, well above ATSDR's minimal risk level of 0.2 micrograms per cubic meter and probably above the EPA's suggested relocation level of 10 micrograms per cubic meter. This experiment is due to begin in late December.
