New Way Of Finding Mold In Homes And Other Buildings
With mold contamination of homes an ongoing concern — and a special threat to the 2.5 million foreclosed houses in the U.S., shuttered with little ventilation — scientists are reporting a new method to detect and identify low levels of airborne mold. The report, which describes a simple, fast method that could provide an early indication of potential contamination, appears in ACS' journal Environmental Science & Technology.
Sutapa Ghosal and colleagues indicate that mold contamination of homes, especially after water damage from storms and floods, is an ongoing concern. Although most molds are harmless, scientists have linked some with health risks to humans. Traditional methods for detecting mold contamination involve identifying the spores that mold release into the air. Those tests are labor- and time-intensive, often requiring that the mold grow in the laboratory. Moreover, not every mold can grow under these conditions. That's why the researchers have sought to develop a fast and easy method that can reliably detect and identify low levels of airborne mold — even single spores.
