Chapter 1 – RCS and its potential health effects
The RCS particles are so fine that, if we inhale them, they can penetrate deep into the lung.
Tap the hotspots in the image to find out more about RCS particles in the lung.
There are three to find, when you’ve found them all, move on!

The ‘Respirable fraction’ is under 10 microns in size and reaches deep in the lung.
The thoracic area is where particles of 10-30 microns settle.
The largest inhalable particles (30-100 microns in size) settle in the larynx area.
