What is the main route of exposure in mold remediation projects?

In mold remediation projects, the primary route of exposure is inhalation. This is particularly significant because mold spores and mycotoxins are aerosolized during the remediation process. When disturbed, such as during cleaning, removal, or demolition of contaminated materials, these spores can become airborne and readily enter the respiratory system when inhaled.

Inhalation poses a considerable risk because the respiratory tract is directly linked to the lungs, which makes it an efficient pathway for mold spores and other microbial contaminants to enter the body. This is why personal protective equipment (PPE), such as respiratory protection, is essential during mold remediation operations to minimize the risk of health effects associated with inhaling these harmful particulates.

While skin absorption, ingestion, and injection can also present risks in various contexts, they are not the primary concern in the context of mold remediation. Skin contact can happen, but effective PPE reduces that risk significantly. Ingestion would likely occur only if contaminated materials were handled and then transferred to the mouth without proper hygiene practices, but this is less common in remediation work. Injection is not a typical concern in mold exposure scenarios.
