Major measures to reduce mercury pollution in light sources abroad
Mercury plays an important role in the light-emitting mechanism of light sources, and it can improve the luminous efficiency. Therefore, most of the illumination sources currently used contain mercury. However, mercury is a highly toxic heavy metal. How to avoid or minimize mercury pollution in lighting sources has become an urgent problem to be solved. Many industrialized countries have taken many measures to reduce mercury pollution in lighting sources, and have achieved good results. These measures mainly include the following: First, to raise people's awareness of mercury pollution in lighting sources, many countries have clearly defined the mercury-containing light bulbs as harmful wastes through legislation, prohibiting people from discarding mercury-containing bulbs and taking measures. Strengthen the recycling of used light sources. Second, instruct the manufacturer to improve the quality of the light source and reduce the mercury content in the lamp. For example, the Swedish Environmental Protection Agency has developed a plan called “From Cradle to Grave†to solve the problem of mercury pollution in the light source through economic leverage. If the relevant manufacturers do not do enough in this regard, they will be subject to certain economic penalties. Third, promote energy-saving light sources. Countries are vigorously promoting compact energy-saving fluorescent lamps instead of incandescent lamps and promoting the use of energy-saving light sources such as high-intensity gas discharges. Under the premise of ensuring the quality of lighting, the use of electricity is reduced, thereby reducing mercury pollution.
