      <subfield code="a">Passive badges have been utilized for many years throughout the industrial hygiene community for the sampling of organic vapors in air. A laboratory comparison was made of the 3M 3500 organic vapor monitor versus charcoal tubes in both short-term and full-shift scenarios. Back diffusion, humidity effects, concentration effects, storage stability, competing solvents, intermediate-dusration spikes, short-duration spikes, and fluctuating concentrations were all investigated</subfield>
