Diffusive samplers personal exposure

Bailey, A., and Hollingdale-Smith, P.A., A Personal Diffusion Sampler for Evaluating Time-Weighted Exposure to Organic Gases and Vapors Annals Occup. Hyg. 1977, 0, 345-356. [Pg.222]

Ullrich et al. (1996) used the OVM 3500 sampler in a study of indoor, outdoor and personal exposure concentrations involving 156 people in eastern Germany. The diffusive sampler was worn by subjects for either 2 days or 2 weeks. Samplers were also exposed simultaneously to measure VOCs in indoor and outdoor air. [Pg.58]

Atmospheric kinetic samplers, sometimes referred to as diffusion samplers , have a long history of use in roles such as personal monitors or dosimeters to evaluate personal exposure or... [Pg.19]

Based on the research of Dr. E. D. Palmes (1) at New York University s Institute of Environmental Medicine and on additional study supported by a contract from the United States Bureau of Mines, a unique personal sampler has been designed to passively collect N0X. This is accomplished by way of molecular diffusion and subsequent trapping of the molecules onto a matrix coated with triethanolamine (TEA) at the closed end of the sampler. Constructed of polypropylene, the tubular sampler shown in Figure 1 is small, lightweight, unbreakable and can be easily worn in the breathing zone of the employee whose exposure is to be monitored. No pumping mechanism is required. The components of N0X diffuse at constant, known rates towards the sealed end of... [Pg.587]

Available data based on limited exposure tests in chambers and comparisons with pumped sampling methods in the laboratory and field show the techniques can be used to determine mean concentrations of VCX3s over periods of a day to several weeks for fixed site and personal monitoring. Problems of poor recovery at the desorption stage and possible losses by back diffusion means the investigator needs to consider carefully the choice of sampler and, in the case of thermally desorbable tubes, the optimum sorbent for the investigation. [Pg.69]
