The convention to be used is not always straightforward, but generally depends on what part of the respiratory system is affected by the aerosol particles. For example, if an aerosol (for example, silica) is expected to be hazardous mainly in the alveolar regions of the respiratory system, then the respirable convention applies. On the other hand, if an aerosol is extremely soluble (for example, KCN), then the inhalable convention should be used for monitoring or setting exposure limit standards. The conventions are often applied for approximating mass fractions, but they may also be used in the evaluation of total surface area or the number of particles in the collected material.
The conventions have now been adopted by the International Standards Organization (Technical Report ISO TR 7708), the Comit? Europ?en de Normalisation (CEN Standard EN 481), and the American Conference of Governmental Industrial Hygienists (ACGIH) (1). The definition of respirable aerosol is the basis for recommended exposure levels (REL) of respirable coal mine dust as promulgated by NIOSH (Criteria for a Recommended Standard, Occupational Exposure to Respirable Coal Mine Dust). The respirable aerosol definition also forms the basis of the NIOSH sampling method for respirable particulates not otherwise regulated (NIOSH Manual of Analytical Methods).
The conventions constitute a part of the performance characteristics required of aerosol samplers for collecting aerosol according to the relevant health effects. This guide therefore does not specify particular samplers for measuring the aerosol fractions defined here. Detailed guidelines for evaluating any given sampler relative to the conventions are under preparation. Several advantages over instrument specification can be attributed to the adoption of these performance-associated conventions:
The conventions have a recognized tie to health effects.
Performance criteria permit instrument designers to seek practical sampler improvements.
Performance criteria promote continued experimental testing of the samplers in use with the result that the significant variables (such as wind speed, particle charge, and so forth) affecting sampler operation become understood.
1.1 This guide defines conventions for personal samplers of specific particle-size-dependent fractions of any given non-fibrous airborne aerosol. Such samplers are used for assessing health effects and in the setting of and testing for compliance with permissible exposure limits in the workplace and ambient environment. The conventions have been adopted by the International Standards Organization (Technical Report ISO TR 7708), the Comit? Europ?en de Normalisation (CEN Standard EN 481), and the American Conference of Governmental Industrial Hygienists (ACGIH) (1). The conventions were developed (2) in part from health-effects studies reviewed (3) by the ACGIH and in part as a compromise between definitions proposed by the ACGIH (3) and by the British Medical Research Council (BMRC) (4). Conventions are given here for inhalable, thoracic, and respirable fractions.
1.2 This guide is complementary to Test Method D4532, which describes the performance of a particular instrument, the 10-mm cyclone, and operational procedures for use. The procedures, specifically the optimal flow rate, are still valid although the estimated accuracy differs somewhat from use with previous aerosol fraction definitions. Details on this instrument and also the Higgins-Dewell cyclone have recently been pu......
