Long term changes in the concentration of radium in discharge waters of coal mines and Upper Silesian rivers

Natural Radioactivity in Polish Coal Mines: An Attempt to Assess the Trend of Radium Release into the Environment

“…3 Comparison of the assessments of the daily activity of radium isotope inflows to coal mines, in discharge waters and sediments in 1995 and 2016 [MBq/day] Fig. 4 Distribution of the daily activity of radium 226 Ra + 228 Ra in water flowing into coal mines and total radium activity within each group of coal mine radium on the river beds and contamination of adjacent areas by released brines is, in our opinion, an important environmental problem in the USCB (Chałupnik et al 2017).…”

“…Since then, the daily release of radium isotopes has been assessed regularly by monitoring radium concentrations in formation waters flowing into underground workings, and in the waters that then discharge to the natural environment. However, only rough estimates were made for individual or groups of mines (Chałupnik et al 2017). Detailed analyses of radium concentrations in formation waters at all mine levels have not been conducted.…”

Heavy Metals and Cancer

“…Occupational and environmental presence of radium generates opportunities for exposure to ionizing radiation. Coal mining has been noted as one of the most relevant occupations with risk for exposure [92]. Wastewater drained from mines also carries potential for environmental radium contamination [92].…”

Radium presents further occupational hazards from exposure sources that include soil, building materials and water systems [93].…”

“…A nivel mundial, las investigaciones sobre la contaminación de las aguas continentales son un tema de actualidad. Se ha estudiado, por ejemplo, los efectos del níquel en los ríos de la cuenca amazónica (Holland et al, 2017); el impacto del radio procedente de minas de carbón en aguas de río de Polonia (Chalupnik et al, 2017); la abundancia de disolventes orgánicos en aguas de ríos, lagos y mar de China (Xu y Guo, 2017); el riesgo acuático generado por pesticidas en ríos de la cuenca del Mediterráneo (Silva et al, 2015). En Perú, la situación de los recursos hídricos continentales es crítico, pues la contaminación de las aguas, suelo, flora y fauna asociados a las cuencas de los ríos debido a los residuos de las actividades minera, petrolera, doméstica e industrial; la expansión territorial no planificada de las ciudades y los continuos derrames de hidrocarburos en la selva norte y central, configuran una visión poco alentadora sobre la conservación de dichos recursos en el país (INRENA, 1996;MINAM, 2009).…”
