Uncertainties in this screening characterization include assumptions about room size, ventilation, age of lamp, the distribution of mercury in the room, and also the choice of the toxicity benchmarks used to develop the hazard quotients.Ĭopyright © 2011 Elsevier Inc. A review of release scenarios, along with duration-adjusted toxicity benchmarks, indicated that few releases produced levels of concern, but some scenarios resulted in exceedance of risk targets and require further study. I bought a package of these bulbs for our home recently and found everyone of them cracked open and wondered if the ones handling these broken bulbs might have a bad case of mercury poisoning. ![]() ![]() When the room was ventilated and the broken CFL was cleaned-up, mercury concentrations were generally lower. For questions about this fact sheet, contact the New York State Department of Health at 51 or 80. For the no clean-up scenario, hazard quotients were generally less than 1, suggesting an unlikely health risk. Detailed information on disposal of mercury and mercury-containing items is available from the New York State Department of Environmental Conservation, Division of Environmental Remediation at 51. (2008) were compared to human toxicity benchmarks to calculate hazard quotients. ![]() Concentration data from multiple exposure scenarios tested in a study by Stahler et al. Human health risk to infants/toddlers and adults was evaluated based on two exposure scenarios from compact fluorescent lamp (CFL) breakage first in a room with no ventilation and no clean-up, and second in a room with adequate ventilation and clean-up.
