Presence of contamination by As Cd, As, Pb, Se, and Hg in coals of the Cundiboyacense area, Colombia
Coals of Cundiboyacense area were studied in order to determine their presence and quantify of content of contaminants such as cadmium (Cd), arsenic (As), lead (Pb), selenium (Se), and mercury (Hg), which are compared with Clarke index for coals of the same rank. Coal samples were taken from active...

| description | Coals of Cundiboyacense area were studied in order to determine their presence and quantify of content of contaminants such as cadmium (Cd), arsenic (As), lead (Pb), selenium (Se), and mercury (Hg), which are compared with Clarke index for coals of the same rank. Coal samples were taken from active mining fronts and are analyzed by proximate analysis, petrographic and inductively coupled plasma mass spectrometry (ICP-MS). The results show that analyzed samples contained metals such as Pb (15.5 mg•kg-1), Se (16.05 mg•kg-1), Cd (0.55 mg•kg-1) and As (16.05 mg•kg-1) above the world average for coal of the same rank and higher concentrations than the carboniferous area of northern Colombia, the Hg content is low (< 0.08 mg•kg-1). The content of these elements generates environmental concern. According to the Environmental Protection Agency of US (EPA) the maximum allowed for Se, Pb, and Cd is 0.05 mg•kg-1(ppm). It is suggested that conducting specific studies that allow prefetching and / or use of coals. |

Coals of Cundiboyacense area were studied in order to determine their presence and quantify of content of contaminants such as cadmium (Cd), arsenic (As), lead (Pb), selenium (Se), and mercury (Hg), which are compared with Clarke index for coals of the same rank.

It is suggested that conducting specific studies that allow prefetching and / or use of coals. 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.
