Environmental measurement techniques diffusive monitors

Compared with methods for the workplace, methods for diffusive sampling of non-occupational indoor air and ambient air have been less well developed. The range of concentrations and environmental conditions used to evaluate samplers for workplace monitoring is not directly applicable to non-occupational environments. However, diffusive monitors are Ending increasing use in non-occupational environments. This chapter discusses the principles governing diffusive sampling and the factors that can influence sampler performance, and reviews studies that have applied the technique for the measurement of VOCs in indoor air.
