Abstract
Asbestos ore was sampled from a historical anthophyllite mine in Staten Island, New York. High-resolution transmission electron microscopy (HRTEM) was used to image the structure of nineteen fibers of the anthophyllite asbestos. The anthophyllite was characterized by a high level of chain width disorder, involving wide chain multiplicity faults (CMFs) that were frequent in fibers, randomly spaced, and ranged from one to eight chains in width. This chain width disorder was manifest by streaking of electron diffraction rows of chain width. The anthophyllite asbestos fibers were found to be produced by longitudinal splitting rather than crystal growth. Such splitting is a function of cleavage along CMFs rather than crystal boundaries. The morphology of the fibers is consistent with anthophyllite asbestos mined in Finland associated with lung cancer and mesothelioma. These findings may have regulatory implications.
期刊介绍：
Archives of Environmental & Occupational Health , originally founded in 1919 as the Journal of Industrial Hygiene, and perhaps most well-known as the Archives of Environmental Health, reports, integrates, and consolidates the latest research, both nationally and internationally, from fields germane to environmental health, including epidemiology, toxicology, exposure assessment, modeling and biostatistics, risk science and biochemistry. Publishing new research based on the most rigorous methods and discussion to put this work in perspective for public health, public policy, and sustainability, the Archives addresses such topics of current concern as health significance of chemical exposure, toxic waste, new and old energy technologies, industrial processes, and the environmental causation of disease such as neurotoxicity, birth defects, cancer, and chronic degenerative diseases. For more than 90 years, this noted journal has provided objective documentation of the effects of environmental agents on human and, in some cases, animal populations and information of practical importance on which decisions are based.
