"Toxic mold" is becoming a problem of monumental proportions. Exposure to mold growth in residential, public and commercial buildings is believed to have caused serious medical conditions. Property damage from mold growth has destroyed millions of dollars in real estate and forced homeowners to the curb.  In an effort to protect people from the detrimental effects of toxic mold, congressman John Conyers introduces H.R. 5040, "The Melina Bill".

Air in the indoor environment has a natural tendency to carry microbes. This fact, coupled with tighter, energy efficient buildings have caused an exponential growth in the health risks due to such. This emphasizes the need for air sampling to monitor occupied spaces which include residential environments and commercial building environments.
