While there is no specific amount of breakage that is considered accidental, less than 5% is generally acceptable. The simple assumption of a complete evaporation of the Hg content from a broken light bulb apparently results in a wide overestimation of air concentrations of Hg over time. Some news reports have raised concerns that broken CFLs could result in harmful air concentrations of mercury in the room where the bulb is broken… A new method was developed for measuring mercury released from broken bulbs. Businesses and industries that qualify as universal waste handlers must follow specific requirements for storing, transporting and disposing of these wastes.

An article in the August 2009 official magazine of the Illuminating Engineering Society of North America concluded that a worst-case scenario of mercury exposure (PDF) from a broken bulb is equivalent to eating one serving of fish. Mercury is essential to a fluorescent bulb's ability to emit light; no other element has proved as efficient. this mercury released when the bulbs are discarded and broken have varied widely. HOW MUCH MERCURY IS IN A CFL BULB? (See the Nov. 23 blog.) A small percentage of this mercury can be released into the air if the bulbs are broken. 2. CFL bulbs contain a very small amount (4-6 mg) of elemental mercury inside the glass tubing. Its “quicksilver” identity fueled car brands; its thermal properties made it ubiquitous at one time in thermometers of every sort. Take the broken glass to one of the recycling centers above. A Jerome 411 Gold Film Mercury Vapor Analyzer 10 was used to detect mercury vapor released from the broken bulbs. Mercury vapor released from broken compact fluorescent light bulbs can exceed safe exposure levels for humans, study finds. With the assumption that all mercury released is elemental vapor, it was found that between 17 and 40% of the mercury in broken low-mercury fluorescent bulbs is released to the air during a Mercury, lead and other heavy metals all have the potential to be hazardous wastes. EPA CFL Clean-up Site. For those concerned about the potential risks from mercury vapor in broken CFLs, an August 2009 article written by scientists at Lawrence Berkeley … ... Fluorescent Light Bulbs … This term includes mercury-containing wastes like certain batteries, thermostats, barometers, manometers, temperature and pressure gauges, certain switches, and light bulbs. (2011, July 6). Indeed, most of the released Hg may re-condense, due to the low volatility of Hg.
