La revue de la littérature ne permet pas d’affirmer des certitudes concernant la toxicité des FCR notamment du fait du petit nombre de travailleurs impliqués dans les cohortes, de la relativement courte période de surveillance et du niveau moyen d’exposition relativement bas dans les études réalisées en production.
Les FCR différent de l’amiante par leurs caractéristiques morphologiques et physicochimiques. Leur clivage transversal et leur biopersistance plus faible laissent raisonnablement supposer une toxicité moindre par rapport aux fibres d’amiante.
Deux observations concernant les FCR sont néanmoins particulièrement interpellantes :
- L’observation de corps pseudo-asbestosiques dans le liquide de lavage broncho-alvéolaire de travailleurs exposés aux FCR.
- La relation mise en évidence dans certaines études entre l’exposition aux FCR et l’existence de plaques pleurales.
Ces observations, pour leur similitude avec les fibres d’amiante, sont inquiétantes. Il est donc nécessaire dès à présent de restreindre l’usage des FCR aux applications pour lesquelles il n’y a pas de solution technique à moindre risque pour la santé. Lorsque l’utilisation des FCR est indispensable, des procédures d’utilisation ainsi qu’une surveillance de la santé des travailleurs doivent être mis en place en fonction de l’analyse de risque.
En Belgique, à l’heure actuelle, on ignore le nombre de travailleur exposés ainsi que l’intensité de leur exposition. Les médecins du travail doivent, dès lors, dans le cadre de leur mission d’évaluation des risques, établir l’inventaire des travailleurs exposés aux FCR

This book entitled Zeolites is a collection of papers recently published in the journal Crystals, focusing on zeolites as a group of hydrated aluminosilicates with unique physical and chemical properties that can have numerous and important applications. The collection opens with works related to the geological documentation of the newest deposits of natural zeolites. The second part of the book describes a variety of synthesis methods and characterizes the resulting products. Finally, some recent advances in their applications in different fields are presented at the end of the book.
