Field populations of daphnids historically-stressed by metal contamination may show increased resistance to those contaminants. This study was undertaken aiming to confirm/infirm three main hypotheses: (1) field populations living in historically-impacted environments are more tolerant to metal stress than populations from reference sites; (2) resistance differences are genetically-determined, ...

The legacy of mining continues to affect stream water quality throughout the western United States. Traditional remediation, involving treatment of acid mine drainage from portals, is not feasible for the thousands of abandoned mines in the West as it is difficult and expensive. Thus, the development of new methods to address acid mine drainage is critical. The purpose of this study was two fol...

Abstract To investigate the factors affecting wettability of copper mine blasting dust, primary dust was collected from an open-pit and separated into hydrophilic (HLBD) hydrophobic (HBBD) using water flotation method. The physicochemical properties HLBD HBBD were measured compared with each other. included particle size distributions (PSDs), micromorphologies, pore structures, mineral componen...
