Evidence implicating fibre diameter in the development of mesotheliomas and pulmonary fibrosis is now generally accepted but the contribution that the length of mineral fibres makes is not so well established. As the difference in length of fibers found in the urban situation, and that in the occupational and para-occpational environments is revealed, so the importance of length may increase. Our investigations, reported here, confirm the concept that fibre length is a significant factor in the development of these asbestos related diseases.
