Resumen

Carbones de la zona cundiboyacence fueron estudiados, con el fin de determinar la presencia y cuantificar los contenidos de elementos contaminantes como: cadmio (Cd), arsénico (As), plomo (Pb), selenio (Se) y mercurio (Hg), estos elementos son comparados con los índices de Clarke para carbones del mismo rango. Las muestras de carbón fueron tomadas de frentes de explotación activa y son analizadas mediante análisis próximos, petrográficos y por espectrometría de masas con plasma acoplado inductivamente (ICP-MS). Los resultados revelan que las muestras analizadas presentan contenidos promedio de metales como Pb (15,5 mg•kg-1), Se (16,5 mg•kg-1), Cd (0,55 mg•kg-1) y As (16,05 mg•kg-1) por encima del promedio mundial para carbones del mismo rango y sus concentraciones son mayores a los carbones de la zona norte carbonífera de Colombia, el contenido de Hg es bajo (< 0,08 mg•kg-1). El contenido de estos elementos genera preocupación ambiental ya que de acuerdo a la Agencia de Protección Ambiental de los Estados Unidos (EPA), el límite máximo permitido para el Se, Pb y Cd es de 0.05 mg•kg-1(ppm). Se sugiere realizar estudios específicos, que permitan la recuperación previa y/o utilización.

Palabras clave
