EN ISO 13138 Air quality - Sampling conventions for airborne particle deposition in the human respiratory system - Particle deposition criteria are presented for size-selective aerosol samplers so as to approximate the deposition efficiency of distinct areas of the human respiratory system. Sampling criteria are given for extrathoracic, tracheobronchial, and alveolar collection of both fine and ultrafine nonfibrous particles. The deposition criteria, together with a particle metric related to health-effects, such as particle surface area or mass, then determine specific sampling needs. The criteria complement internationally accepted sampling conventions defined in terms of penetration, rather than deposition within the respiratory tract. The traditional conventions were developed around available instrumentation and particle mass, and are considered conservative indicators of exposure. However, the deposition criteria are expected to lead to better correlation between air quality assessment and adverse health effects, especially when sub-micrometer particles are significant. The sampling criteria are necessarily approximations in view of the variety of ambient conditions and the diversity both between and within individuals given different activity levels. Despite the variations, specific reference human breathing characteristics are adopted so as to obtain definite yet meaningful criteria. The criteria, once established, are expected to stimulate instrument development and to be applied initially in health effects research. Estimation of an uncertainty component associated with the bias between candidate and ideal sampler is outlined for the case of mass-based sampling. Relationships between estimates from penetration as compared to deposition mass-based sampling are given in the mean over a set of particle size distributions. Such relationships are needed for historical continuity, and the associated uncertainties are indicators of the disparity between penetration and deposition.
