Comparability of semivolatile organic compound concentrations from co-located active and passive air monitoring networks in Europe
Passive and active air-sampling results from 10 years of monitoring for 28 semivolatile organic compounds at six sites across Europe are compared and recommendations for interpreting passive air-sampler results are offered.

Graphical tools for the planning and interpretation of polyurethane foam based passive air sampling campaigns
Charts display the length of the linear uptake period, the time to equilibrium, and the loss of depuration compounds for the PUF-PAS. Required are only the length, temperature, and wind speed of deployment and the chemical partitioning properties.
