Description of key information

The results indicated that 0.1% w/w of Chlorendic anhydride was smaller than 10 μm.

Additional information

The different particle sizes defined in EN 481 are:

- inhalable fraction (the mass fraction of particles that can be inhaled by nose and mouth. Particles >100 μm are not included in the inhalable convention

- thoracic fraction (the mass fraction of particles that passes the larynx). It has been shown that 50% of the particles in air with an aerodynamic diameter of 10 μm belong to the thoracic fraction.

- respirable fraction (the mass fraction of particles that reaches the alveoli) It has been shown that 50% of particles with an aerodynamic diameter of 4 μm belong to the respirable fraction

This shows that chlorendic anhydride does not contain significant content of thoracic or respirable fractions but that 31.2% represent an inhalable fraction.
