2. Sources OF MOLD Pores wafting through the air
Undiscovered or unaddressed moisture
Grows on wood, paper, carpet, foods

3. TYPE OF POLLUTANT
Mold is a secondary pollutant. This is because it results from the interaction of the pores and a natural atmospheric constituent, mainly moisture. These conditions make it possible for the mold to survive and grow.

4. HUMAN HEALTH EFFECTS
Common health issues that result from exposure to mold are allergic reactions and asthma attacks.

5. ENVIRONMENTAL EFFECTS
Just as it does in buildings, mold can cause damage to wood. This leads to dry rot, which can create structural issues for trees.

6. PREVENTION/REDUCTION
Because mold’s main cause is moisture, most methods strive to eliminate it. These include increasing ventilation, using air conditioners and de-humidifiers, and using exhaust fans when completing kitchen tasks.
