Mercury Emissions by Use of Compact Fluorescent Lamps and by Generation of Electrical Energy Based on Fossil Fuels

Compact fluorescent lamps (CFL) are an efficient alternative lighting. However, they contain mercury (Hg), metal having adverse effects on health and the environment. The objetive of this study was to compare mercury emissions from the use of CFL and electric power generation based on fossil fuels in Argentina, Bolivia, Ecuador and Venezuela. Indicators were constructed from data published by the World Bank and national institutions in the electricity sector of the countries analyzed, and the emission factors mercury activity published by the United Nations Environment Programme. The results show that Venezuela is the country with most CFL incorporated in its territory, Argentina is the country with more emissions of mercury to the environment by thermal power generation and on Ecuador is the country with more reduction of mercury emissions by saving in thermal generation due to the use of CFL.
