MVOCs are only found at elevated concentrations when there is live, growing mold present. Growing mold increases the likelihood of active, spore-bound micotoxins that have been shown to cause severe respiratory problems. The sample collection process for general indoor air contaminants, including solvents and BTEX, is identical to the collection process for MVOCs. In most cases, a grab sample is collected which takes only a few seconds to complete. Rapid sampling enables quick screening of a large number of indoor air environments.
