Optical microscopy remains the basic means for the study of particulate pollution. Very accurate measurement of the refractive index can be obtained by the use of the λ variation method in phase contrast microscopy. Results obtained on quartz dust and amosite fibres extracted from the human lung are discussed.La microscopie optique reste l'outil de base pour l'étude de la pollution particulaire. La microscopie en contraste de phase permet, entre autres, la mesure très précise de l'indice de réfraction par la méthode de variation de λ. Des résultats obtenus sur des poussières de quartz et des fibres d'amosite extraites du poumon humain sont discutés.Goñi Juan C., Jaurand Marie-Claude, Caye René.
