Demonstration of Direct-on-filter FTIR to Estimate Silica, Kaolinite, and Calcite Mineral Fraction in Respirable Coal Mine Dust Samples
Respirable coal mine dust (RCMD) has long been recognized as an occupational health hazard. In addition to coal, RCMD can contain minerals such as crystalline silica (i.e., most often present as quartz). There has been a resurgence of lung diseases among US coal miners since the late-1990s which …

Investigating the Effects of Particle Loading and Agglomeration on Respirable Coal Mine Dust Particle Classification by SEM-EDX
… mine dust (RCMD) still poses serious occupational health hazards to coal miners and can lead to incurable lung diseases such as coal workers' pneumoconiosis (CWP, also referred to as "black lung"). Further, CWP can develop into a more severe form known as progressive massive fibrosis (PMF). …

Rapid FTIR analysis for respirable crystalline silica monitoring in coal mines using readily available sampling equipment
… exposed to respirable coal mine dust (RCMD) in conjunction with respirable crystalline silica (RCS). Overexposure can pose serious health risks, including development of coal workers' pneumoconiosis (CWP) (also known as "black lung"). CWP has the potential to progress to a more consequential form …

Application of Fourier-transformed-infrared spectroscopy to quantitate amorphous silica in personal air samples in sugarcane cutters
In recent years, chronic kidney disease of unknown origin (CKDu) has risen to an epidemic level in Latin America. Specifically, in agricultural communities of sugarcane cutters, the burden of the disease is unusually high. Several hypotheses exist as to the cause of the disease, focusing on various …

Toward Rapid Silica Analysis of CPDM Samples using Portable Fourier Transform Infrared Spectrometry
Continuous personal dust monitors (CPDMs) are widely used to monitor respirable coal mine dust (RCMD) to reduce miners' exposures, but they are unable to directly assess respirable crystalline silica (RCS) concentrations, which are linked to the recent rise of respiratory diseases among coal …
