• Description:
  Development of alternative protocols for performance evaluation of personal aerosol samplers has shifted to the forefront of aerosol science and practice. Traditional evaluation protocols developed for large wind tunnels utilizing full-size manikins are time consuming and expensive. In addition, the accuracy and precision of the tests performed in a large wind tunnel are often not sufficient, particularly because of the limitations in achieving uniform aerosol concentration in the test zone (Kenny et al., 1997, Ramachandran, Sreenath, and Vincent, 1998). Several approaches have recently been proposed to solve this problem. One of them suggests using the scaling relationship and semi-empirical aspiration models (Ramachandran et al., 1998). This allows to address spatial and temporal concentration uniformity issues. Another approach introduces a small torso as an integral part of a simplified protocol which can be utilized in a smaller wind tunnel (Witschger et al., 1998). This protocol permits significant reduction of the number of experiments involved in the comprehensive performance evaluation of personal aerosol samplers. At the same time, accuracy and precision of these experiments can be maintained at acceptable levels. In this study, the simplified protocol was evaluated with three commercially available personal aerosol samplers using a full-size manikin and a small (simplified) torso.
