IMA WORKING GROUP ON “Asbestos, asbestiform minerals, and other respirable minerals that pose potential negative health risks”.

In the actual scenario, there is ambiguity in the definitions of asbestos and non-asbestos species and this leads to widespread confusion in the regulatory process and consequences for the social and health issues. Ambiguity and miscommunications can lead to unnecessary media hysteria and public alarm! There is NEED FOR UNIQUE CLEAR DEFINITIONS AND CLASSIFICATION. The main goal of the international working group is to open the discussion on the definitions of “fiber”, “asbestos”, “asbestiform”, “EMP”, “ECF” and related terms and the role of asbestiform fibers other than asbestos like erionite and ferrierite.
