This groundbreaking book explores the complex world of elongate mineral particles (EMPs) critical occupational and environmental agents with significant public health implications. It carefully distinguishes between asbestiform EMPs, which pose serious health hazards to humans, and non-asbestiform elongate particles such as cleavage fragments, which have different characteristics and lower (or negligible) health risks. This distinction is vital for accurate risk assessment and appropriate regulatory approaches in both occupational and environmental contexts.
The comprehensive volume covers multiple scientific aspects of EMPs, including their geological origins and mineralogy, specialized analytical characterization methods, toxicological properties and carcinogenic potential, and the specific dimensional parameters that influence their toxicity. It also addresses classification methodologies for distinguishing between asbestiform and non-asbestiform particles, examines how EMPs interact with the human respiratory system, evaluates current regulatory frameworks while identifying needed improvements, and presents illuminating case studies on EMP risk assessment.
Elongate Mineral Particles: Characterization, Classification, and Risk Analysis is written for professionals across multiple disciplines. This book serves as an essential resource for health and safety specialists, industrial hygienists, toxicologists, epidemiologists, mineralogists, public health personnel, and pathologists. Its accessible yet scientifically rigorous approach makes it valuable for any scientist or practitioner interested in understanding the mineralogy and health effects of asbestos and other fibrous minerals, providing the readers with the knowledge needed to address these important public health challenges.
