    The rising cases of coal worker's pneumoconiosis since the early 2000s have driven research into respirable coal dust. Prolonged quartz dust exposure is deemed to be the primary cause of the resurgence in pneumoconiosis. This study examines how quartz present in coals of various ranks produces hydroxyl radicals (oOH), a reactive oxygen species link ...

    During COVID-19, the general public widely used face-worn products (FwPs) to mitigate viruses spread via airborne transmission. This study investigated the effectiveness of various FwP categories in reducing submicron aerosol transmission by evaluating total outward leakage (TOL) across particle sizes. Nine FwP categories were tested: ASTM F2100 Le ...
