Particle Size: Selective Sampling for Particulate Air Contaminants

Significantly expanded and completely updated, this revision of the 1985 text provides an in-dept look at particle size-selective criteria for aerosol exposure assessment. The book, prepared by the ACGIH® Air Sampling Procedures Committee, considers not only the harmonized criteria agreed upon by such scientific bodies as ISO, ACGIH®, and CEN, but also the new issues that are emerging as a result of the criteria.

The book is divided into two parts. The first covers the background and status of what is now generally agreed upon and adopted. Topics include the scientific rational for particle size- selective sampling in both working and living environments; the essential physiological background; research leading to the development of formal definitions for the inhalable, thoracic, and respirable conventions in the working environment; and the development of corresponding conventions for particles in the ambient atmospheric environment. The history and current status of practical sampling instrumentation for the measurement of various particle size fractions is discussed. A section also reviews the general framework for developing TLVs® and discusses how the new particle size-selective sampling criteria may be applied in that process.
