January 15, 1997. Repeated water incursions cause high humidity. Hot summers and an uninsulated hot water pipe provide significant sources of heat throughout the year. No air circulation keeps mold spores contained. Potential Health Issues Major concerns are toxicity and concentration.
Mold spores are always present in air so high concentration is an issue.
Besides books, they may infect floors, walls, furniture. High concentrations have adverse affects, may cause infections, and molds are powerful sensitizers. Debilitating allergies, athsma or respiratory problems may be triggered, even in people not prone to such health problems. While serious toxic consequences require repeated exposure, vomiting and illness may be caused by a single exposure to a high concentration of mold. Spores remain viable for up to 22 years.
