Biological contamination

Biological contamination

The contamination of a building environment caused by bacteria, molds and their spores, pollen, viruses, and other biological materials (e.g., animal and human dander insect and arachnid excreta). It is often linked to poorly designed and maintained HVAC systems. People exposed to biologically contaminated environments may display allergic-type responses or other physical symptoms.
