Chapter 1 – Recap: RCS and its potential health effects
Long term daily exposure to high levels of RCS, normally over many years, can cause the debilitating lung disease silicosis. There may also be an increased risk of lung cancer.
The images show healthy lungs vs lungs damaged by exposure to RCS.

Healthy Lungs

Lungs damaged by exposure to Respirable Crystalline Silica
In the image of damaged lungs, we see small cloudy areas mainly in the middle and upper parts of the lungs, areas affected by RCS exposure.
