Particulate matter (PM) from mining operations, engines, and ore processing may have
adverse effects on health and well-being of workers and population living nearby. In this …

In underground mines, various mining activities may generate dust or vibrations, affecting
workers' health and safety. Therefore, for worker safety, we must monitor the environment …

Using biodiesel in place of petroleum diesel is considered by several underground metal
and nonmetal mine operators to be a viable strategy for reducing the exposure of miners to …

Direct reading instruments (DRIs) for aerosols have been used in industrial hygiene practice
for many years, but their potential has not been fully realized by many occupational health …

The number and mass size distributions of refractory black carbon (rBC) cores in particles
emitted from a diesel vehicle were investigated as a function of particle mobility diameter (d …

The extensive use of diesel-powered equipment in mines makes the exposure to diesel
