Stahler et al. (2008) found that breaking one lamp on wood, short pile or shag carpet results in almost immediate high mercury concentrations, but if a window is opened and the broken lamp cleaned up, the concentrations fall below 300 ng/m3 in 10 min or less (for the initial scenarios tested). It also appears that variations in exposure levels are primarily due to wattage. Brand A was used for the six original scenarios and it has lowest average concentrations (except brand F, which is also a low wattage lamp), but other brands with higher wattages generally resulted in greater concentrations at 15, 30 and 60 min. There are insufficient data on exposure scenarios utilizing spent lamps. However, there are data that show spent lamps release less mercury than new lamps, and therefore exposure scenarios limited to new lamps represent the worst
case exposure scenario. Spent lamps are not likely to be of greater
health risk when compared to the risk from new lamps.
