18. dix A Other Studies on Mercury Lamp Treatment and Handling A number of other studies have been conducted both on DTCs and on the release of mercury from fluorescent lamps that were broken without any emission controls Some of these studies are discussed here to provide more information about mercury release from broken lamps In 1994 EPA s Office of Research and Development Control Technology Center produced a report entitled Evaluation of Mercury Emissions from Fluorescent Lamp Crushing EPA document no EPA 453 D94 018 The conclusions from this report were that the amount of mercury emitted from a spent lamp depends on the way the lamp is handled after it is removed from service The report concluded that by recovering the mercury in the spent lamps as opposed to disposing of them without recycling the net amount of mercury ultimately released to the environment is reduced Specifically the researchers found that even in a well covered drum top crusher some mercury is emitted during crushing However they also concluded that crushers can be designed to emit up to 90 less mercury through the inclusion of a vacuum collection system to prevent release of mercury from the lamp feed system and air pollution control media such as a cyclone a HEPA filter and a carbon adsorber The Minnesota Department of Health in consultation with the Agency for Toxic Substances and Disease Registry Division of Health Assessment and Consultation pe
