  "field": "Environment",
  "definition": "Passive sampling is based upon distribution of solutes between the sampled medium, e.g. a water body, and a collecting medium, the sampler or sampling medium. Flow of solute from one medium to the other continues until equilibrium is estab-lished in the system, or until the sampling session is terminated by the user. The amount of solute in the sampling medium is then determined analytically and can be used to calculate the concentration in the sampled medium. With exposure until equilibrium, the sampled medium concentration can be calcu-lated based on the solute distribution factor between the two media involved.",
