Molds, fungi and their spores are a natural part of the environment. They are ubiquitous, which is to say they are found everywhere, constantly encountered and widespread. Mold problems in homes and buildings may stem from many sources, however the most common are associated with excessive moisture or elevated humidity for extended periods of time. When certain conditions are met, most importantly temperature and humidity or available moisture, growth may accelerate and amplify.

When disturbed, mold may release microscopic spores into the air in much the same way a dandelion releases seed pods. Air currents can distribute spores far from the original source where, once settled and if appropriate growing conditions exist, new colonies can be established. Aerosolized mold spores may affect those with sensitivities, resulting in symptoms such as itchy, watery eyes, sore throat and in some cases may trigger asthma.

Much has been reported in the media about the negative effects of exposure to mold. Though few species of mold are considered toxic to humans, many are considered to be irritants and a contributing factor to a number of afflictions. Depending on exposure (amount and type) and immune response (sensitivity), common exposure symptoms include:

• Runny nose
• Coughing
• Shortness of breath
• Headaches
• Recurrent colds
• Eye irritation
• Dizziness
• Nausea
• May trigger asthma

Those most susceptible include infants and young children, elderly and convalescents, and immune compromised individuals.
Exposure to elevated levels of mold spores for prolonged periods of time can certainly be cause for concern. For this reason, it is always best to have mold evaluated and removed by certified professionals who have the training and expertise required to identify moisture sources, evaluate mold growth (visible or suspected), contain damage to the smallest possible area, effectively remove contaminated materials and perform or recommend procedures to prevent recurring contamination.
