A study conducted by researchers at the University of Minnesota School of Public Health has found that most containers used for the storage and transportation of used fluorescent lamps to recycling centers do not provide adequate levels of protection against mercury vapors emitted from broken lamps. Mercury vapors inhaled or absorbed through the skin can cause neurological damage; the lamps present occupational and environmental hazards. The study’s purpose was to find out what packaging configuration would reduce the amount of mercury vapor being released. The Environmental Protection Agency has encouraged fluorescence bulb users to package old lamps protectively against breakage.
