“…Mercury, the most persistent hazardous pollutant in heavy metals, can migrate and transfer anywhere via flowing rivers and atmospheric circulation [4,5,6], continually accumulate in organisms [7], and even pollute the Earth’s biosphere by cycling in major environmental compartments and across national boundaries on a global scale for a long time [8,9]. It was reported that approximately 50% of mercury in the environment is from anthropogenic sources [10,11].…”

With the increasing awareness of energy conservation and environmental protection, high energy-consuming incandescent lamps have been largely withdrawn from the stage of mainland China’s lighting industry because the main raw material for electricity production-coal-produces mercury pollution when burned and energy-saving fluorescent lamps have made considerable progress. However, fluorescent lamps emit mercury, which still causes environmental pollution. In this work, the existing problems in the development of fluorescent lamps, and in the collection and treatment of spent fluorescent lamps were analyzed. The contributions of various external factors to the above problems were evaluated based on fuzzy theory. Finally, solutions to control the pollution of mercury from fluorescent lamps and spent fluorescent lamps were proposed. Results show that the biggest problem that causes mercury pollution is the first among three factors: energy conservation and mercury emission from fluorescent lamps and spent fluorescent lamps, spent fluorescent lamp collection and spent fluorescent lamp treatment. The best way to solve these problems is by developing an energy-saving and environment-friendly light emitting diode (LED) industry in mainland China.
