What is CWP? | Miners' health matters
The details. A typical pair of lungs contain approximately 700 million alveoli. Because respirable dust particles are so small, they're able to travel all the way into the alveoli, where they can cause irritation inside the air sac. In response to the dust particles, the lung's defence mechanism kicks in.
