At least one type of Aspergillus species produces aflaxatoxin which is both a toxin and carcinogen. The most common form may cause coughing, fever, chest pains, and breathlessness.

Assessment
Mold assessment is the process of identifying the location, and extent of mold located within a building.

Biocide

Fungus
An organism of the kingdom of fungi, feeding on organic matter.

HEPA
A high efficiency particulate air filter used as part of the remediation process.
