What are MVOCs and when are they typically present?

Microbial Volatile Organic Compounds (MVOCs) are specifically produced by actively growing microorganisms, such as mold, bacteria, and other fungi. These compounds are byproducts of microbial metabolism and can be emitted into the air as a result of microbial activity.

When conditions are favorable for microbial growth—such as adequate moisture, organic material, and suitable temperatures—microorganisms can proliferate, leading to an increase in the production of MVOCs. These compounds can often be detected in indoor environments, particularly those that have suffered water damage or where mold growth is present. The presence of MVOCs can be an indicator of microbial contamination and is often assessed during remediation processes to help identify areas that may require further treatment.

Understanding MVOCs is crucial for professionals in the field of microbial remediation, as these compounds not only indicate microbial activity but may also contribute to poor air quality and health issues for occupants in affected spaces.
