Indoor Air Quality - Assessment of Molds in the Built Environment
Stachybotrys chartarum (S. atra) is a black mold that can sometimes be found growing indoors on paper of dry wall, wood, behind wall paper, on ceiling tiles, etc. in areas that are constantly moist or that have suffered water damage or leaks.
Note that not all black molds are Stachybotrys and that other molds may also occur indoors. Current Canadian recommendations for indoor mold advise building occupants to clean-up and/or remove visible mold growth and to take action to reduce or eliminate moisture.
