Baseline Surface Mold Guidelines Revealed

Surficial samples were collected on Bio-Scan400™ for mold evaluation in buildings and homes. Bio-Scan400™ is a sample collection device for environmental surface sampling. Over six thousand five hundred Bio-Scan™ samples were collected over a period of five years (2004-2008) from both residential and commercial facilities across the United States to find out the types and abundance of mold growing on indoor surfaces such as dry-wall, insulation liner, carpet and other building materials. This study establishes a reliable reference including numerical value in terms of counts/cm2 for evaluating mold in a building. Findings suggest that numerically 50 counts/cm2 should be adapted as a cutoff value for determining normal background mold levels in buildings; although mold population dynamics vary greatly with the nature and composition of the surface.
