Settled Asbestos Dust Sampling and Analysis compiles the most significant data on asbestos in settled dust. This ready reference presents an analysis of settled dusts and surface particles of all sizes for asbestosthat is useful for qualitative and quantitative assessment and helps to determine the source of fibers. The main scope of this reference includes sample collection, sample analyses, and interpretation of settled dust data, as well as the use of such data for purposes including asbestos abatement projects and in-place management programs. Sections on lead and other particulates are also included.

Asbestos minerals have novel properties which make them highly desirable for industrial use. While the health hazards of asbestos have long been recognized and are well documented in the medical literature, ecological and environmental research involving asbestos fibers has only been undertaken in the past 25 years and the significant deleterious effects of asbestos materials on soil and plant ecology has been much less well publicised. This book examines non-occupational exposure and environmental effects of asbestos relating to animal and plant growth in the natural environment. Major nutrient imbalances and excess concentrations of trace metals have been identified as main causes for the poor plant response. Given the complexity of the asbestos analysis and the extent of the problem, this book attempts to bring together the multitude of subjects pertaining to asbestos in the natural environment with the aim of contributing to a better understanding of the chemical characteristics of asbestos-rich materials and their effect on plant growth.

The Defence Research Establishment Atlantic(DREA) has traditionally used scanning electron microscopy (SEM) coupled with energy dispersive x-ray (EDX) spectrometry to identify asbestos fibers in solid insulating materials. This analysis typically utilizes fiber morphology to determine the presence of asbestiform fibers and EDX analysis to characterize asbestos type. The characterization is accomplished by comparison of the relative amounts of magnesium, silicon and iron present in the fibers. The EDX detector traditionally used in asbestos characterization employs a protective beryllium shield that effectively blocks the passage of low energy x-rays. Thus characteristic x-rays from 'light elements' (those below sodium in atomic weight) are not detected. Recently, DREA acquired a commercial EDX detector that employs a polymer shield that allows for detection of x-rays from elements as low as boron in atomic weight. This report summarizes results of a study on the effects of using a light element detector on characterization of both asbestos standards and commercial asbestos-containing insulating material. The study showed that 'light element' SEM/EDX can be used to characterize asbestos fibers in bulk insulations.

Evaluates the risks and human health impacts of asbestos and other fibrous minerals Despite continuous efforts to eliminate asbestos from commercial use, it remains a serious occupational and environmental hazard. Health Risk Assessment for Asbestos and Other Fibrous Minerals provides a rigorous discussion of risk assessment methodology for elongate mineral particles, covering basics, theory, models, and practical applications, enabling readers to participate in carrying out efficient and informed health risk assessments, to estimate potential adverse effects for exposed populations, and to determine the acceptability of risks at a given level of exposure. Coverage includes: Mineralogy, health effects, pathology, exposure assessment, modeling, and characterization of risks for asbestos and similar toxic materials Necessary integration of epidemiology, toxicology, industrial hygiene, and environmental health expertise when performing a health risk assessment Emerging and not-well-known hazards, e.g. erionite and other naturally occurring fibrous minerals Contributions by Garry Burdett, Bruce Case, Lucy Darnton, Daniel Hall, Arseniy Korchevskiy, Brooke Mossman, Cassidy Strode, Robert Strode, and Ann Wylie Case studies and examples of risk calculations Health Risk Assessment for Asbestos and Other Fibrous Minerals is a highly practical reference on the subject for occupational and public health professionals, industry and government regulators, industrial hygienists, and risk assessors, along with epidemiologists, biostatisticians, toxicologists, and other scientific professionals.
