Scattering of mold spore clusters

Research Overview

Status: Ongoing
Substances: Aspergillus fumigatus mold
Nominated: December 2001

Background Information

NTP is currently conducting studies to better understand how exposure to mold may cause disease. Areas being studied include:

  • Fungal organisms which may be causing human health effects
  • Target organs for fungal toxicity
  • Dose-dependent effects, with emphasis on respiratory and immune health effects
  • Identification of biomarkers of exposure and effects

There have been many reports connecting mold exposure to a variety of symptoms including allergic, respiratory, and neurological problems. Increased exposure to mold may be in part due to:

  • Natural disasters
  • New construction methods
  • Better sealing and insulation in buildings

These NTP studies will help us understand the potential causes of symptoms from mold exposure, with the goal of creating healthier buildings and reducing mold-related health issues.

NTP Studies & Findings

NTP is conducting numerous studies in mice to identify potential harm from short and long-term exposure to select molds. These studies will provide toxicology data which can be used by:

  • Other government agencies
  • The public
  • Other stakeholders

The table below lists ongoing NTP studies on molds which include a link to the testing page and any reports or status updates.
