Application of artificial intelligence in the analysis of asbestos fibers

Richard Lee et al. Front Public Health. .

Abstract

Automated asbestos fiber detection and identification has been the goal of asbestos microscopists for decades. The advent of inexpensive memory, fast digital processing, machine learning, and microscope automation provide the enabling platform for success. This paper will review recent developments in fiber detection and identification by PCM and SEM and will present recent progress in employing artificial intelligence in the TEM classification of asbestos and non-asbestos amphiboles in the evaluation of elongated minerals in raw materials. To date, this project has been self-funded.

Keywords: amphibole; artificial intelligence; asbestos; automation; identification.

Comparison of images from two different samples as seen in the transmission electron microscope. The left image shows non-asbestos particles (black arrow) while the right shows asbestos particles (red arrow). These morphological classifications originated with an evaluation of the minerals in hand samples and comply with definitions found in accepted protocols (18, 19).
