Black Mold Remediation & Health Impact: Stachybotrys Chartarum

Stachybotrys chartarum is described as an indoor mold that has been associated with cases of pulmonary hemorrhage in the Cleveland, Ohio area. The study applied two quantitative methods to air samples from a residence where an infant developed pulmonary hemorrhage. Quantitative polymerase chain reaction and a protein synthesis inhibition assay were used to determine S. chartarum spore concentrations and airborne toxicity in samples taken before, during, and after remediation. The remediation programme removed contaminated wallboard, paneling, and carpeting from the water-damaged areas of the home. In addition, a sodium hypochlorite solution was applied to surfaces during remediation.
