          Abstract

          La neumoconiosis es caracterizada por el depósito nodular difuso de polvo en los pulmones como resultado de la exposición prolongada a polvo bituminoso o de antracita en los trabajadores de las minas de carbón. La neumoconiosis de los mineros del carbón también se denomina enfermedad del pulmón negro o antracosis. Un minero del carbón que padece o desarrolla una Antracosis puede presentar numerosos nódulos redondeados pulmonares en poco tiempo. Dichos nódulos aparecen en ocasiones en ausencia de una antracosis simple. A nivel histológico pueden parecerse a los nódulos reumatoides, pero tienen una zona periférica de inflamación aguda. Estos nódulos representan la respuesta inmunológica a la diátesis reumatoide asociada. En Colombia la minería es un factor estratégico a nivel económico para su desarrollo. Sin embargo, existen factores negativos derivados de ésta que giran en una carrera sin control ni reglas claras; esta actividad hace trámite en el territorio, arrastrando una estela de problemas sobre la sociedad, el ambiente, el bienestar y la salud de las personas.

          Pneumoconiosis is characterized by diffuse nodular dust in the lungs as a result of prolonged exposure of workers in coal mines to bituminous dust or anthracite. Pneumoconiosis presented in coal miners is also called black lung disease lung. A coal miner who develops Anthracosis can present numerous pulmonary rounded nodules in a short time. These nodules appear sometimes in the absence of a simple anthracosis. Histologically they may look like resemble rheumatoid nodules, with the difference; they have a peripheral area of acute inflammation. These nodes represent the immune response associated to rheumatoid diathesis. In Colombia, mining is a strategy for economical development. However, there are negative factors arising rotating it in a race without control or clear rules; This activity is pending in the territory, dragging a trail of problems on society, the environment, welfare and People's health

          A pneumoconiose é caracterizada por poeira nodular difusa nos pulmões como resultado da exposição prolongada a poeiras betuminosas ou antracite nas minas de carvão. Pneumoconiose de mineiros de carvão também chamado preto ou preto doença pulmonar pulmão. Um mineiro de carvão que sofre ou desenvolve uma antracose pode apresentar numerosos nódulos pulmonares arredondados em um curto espaço de tempo. Estes nódulos aparecem às vezes na ausência de uma antracose simples. Histologicamente podem assemelhar-se a nódulos reumatóides, mas têm uma área periférica de inflamação aguda. Esses nódulos representam a resposta imune associada à diátese reumatóide. A mineração na Colômbia é um fator estratégico economicamente para o desenvolvimento. No entanto, existem fatores negativos decorrent surgindo girando-o em uma corrida sem controle ou regras claras. Esta atividade está pendente no território, arrastando um rastro de problemas na sociedade, o meio ambiente, bem-estar e da saúde das pessoas.

              Mapping and Prediction of Coal Workers’ Pneumoconiosis with Bioavailable Iron Content in the Bituminous Coals

              Based on the first National Study of Coal Workers’ Pneumoconiosis (CWP) and the U.S. Geological Survey database of coal quality, we show that the prevalence of CWP in seven coal mine regions correlates with levels of bioavailable iron (BAI) in the coals from that particular region (correlation coefficient r = 0.94, p < 0.0015). CWP prevalence is also correlated with contents of pyritic sulfur (r = 0.91, p < 0.0048) or total iron (r = 0.85, p < 0.016) but not with coal rank (r = 0.59, p < 0.16) or silica (r = 0.28, p < 0.54). BAI was calculated using our model, taking into account chemical interactions of pyrite, sulfuric acid, calcite, and total iron. That is, iron present in coals can become bioavailable by pyrite oxidation, which produces ferrous sulfate and sulfuric acid. Calcite is the major component in coals that neutralizes the available acid and inhibits iron’s bioavailability. Therefore, levels of BAI in the coals are determined by the available amounts of acid after neutralization of calcite and the amount of total iron in the coals. Using the linear fit of CWP prevalence and the calculated BAI in the seven coal mine regions, we have derived and mapped the pneumoconiotic potencies of 7,000 coal samples. Our studies indicate that levels of BAI in the coals may be used to predict coal’s toxicity, even before large-scale mining.
