A: A committee of the World Health Organization estimates that as many as 30 percent of new or remodeled buildings may have unusually high rates of sick building complaints. While this is often temporary, some buildings have long-term problems which linger, even after corrective action. The National Institute for Occupational Safety and Health (NIOSH) reports that poor ventilation is an important contributing factor in many sick building cases.
A: Mold requires nutrients, water, oxygen, and favorable temperatures to grow. Nutrients for mold are present in dead organic material such as wood, paper or fabrics; mold can also derive nutrients from some synthetic products such as paints and adhesives. Mold requires moisture, although some mold species can obtain that moisture from moist air when the relative humidity is above 70 percent. Many molds thrive at normal indoor temperatures; few if any molds are able to grow below 40°F or above 100°F.
A: Excessive mold spores indoors can trigger allergic reactions, breathing disorders, and asthma attacks. Mold can cause adverse health effects, regardless of whether the mold is alive or dead.
A: Any mold can be dangers if an individual has developed sensitivites to it. Some molds that produce toxins are considered by many doctors to be more dangerous than others. Some of the molds that produce dangerous toxins include Stachybotrys, Aspergillus, Trichoderma, and Penicillum. These molds are most commonly found indoors when water damage occurs.
A: If the mold covers more than 10 square foot of space a professional mold remediation company should be contacted. In some cases professional remediation is recommended even if there is less than 10 square feet. The mold should be removed under controlled conditions to prevent the mold spores from being transported throughout the indoors. As a general rule, mold should be removed and not encapsulated or treated (e.g. sprayed with bleach). Professional remediation companies should never perform the testing and the remediation due to a conflict of interest.
A: While there are hundreds of molds that are black in color, the term “black mold” is generally used to reference Stachybotrys. Stachybotrys is a black, shiny mold that grows on very wet drywall, particle board, ceiling tiles, and wood. Because this mold produces potent toxins and some medical experts have attributed it to serious illness including neurological disorders, excessive bleeding, gastrointestinal disorders, and inflammation, it has received more notoriety than other types of mold.
A: Sick building syndrome (SBS) is a situation in which occupants of a building experience acute health effects that seem to be linked to time spent in a building, but no specific illness or cause can be identified. The complaints may be localized in a particular room or zone, or may be widespread throughout the building.
A: Building occupants complain of symptoms associated with acute discomfort. These symptoms include headaches; eye, nose, and throat irritation; a dry cough; dry or itchy skin; dizziness and nausea; difficulty in concentrating; fatigue; and sensitivity to odors. With SBS, no clinically defined disease or specific chemical or biological contaminant can be determined as the cause of the symptoms. Most of the complainants feel relief soon after leaving the building.
