Stachybotrys chartarum

Stachybotrys chartarum is a fungus that belongs to the division Ascomycota. It is commonly known as "black mold" or "toxic black mold" due to its dark green or black appearance and its potential to produce mycotoxins. This species is often found in water-damaged buildings and can pose significant health risks to humans.

Description

Stachybotrys chartarum is a saprophytic fungus that thrives on materials with high cellulose content, such as drywall, wood, and paper. It requires constant moisture to grow, making it prevalent in areas with water damage or high humidity.

Health Effects

Exposure to Stachybotrys chartarum can lead to a variety of health issues, particularly in individuals with respiratory conditions, allergies, or weakened immune systems. Symptoms of exposure may include coughing, sneezing, eye irritation, skin rashes, and in severe cases, pulmonary hemorrhage in infants. The mycotoxins produced by this mold, such as trichothecenes, are believed to be responsible for these adverse health effects.

Detection and Remediation

Detecting Stachybotrys chartarum typically involves visual inspection and sampling of the affected areas. Air sampling and surface sampling are common methods used to identify the presence of this mold. Remediation involves removing the contaminated materials, addressing the source of moisture, and thoroughly cleaning the affected areas to prevent regrowth.

Prevention

Preventing the growth of Stachybotrys chartarum involves controlling indoor humidity levels, promptly repairing water leaks, and ensuring proper ventilation in areas prone to moisture accumulation. Regular maintenance and inspection of buildings can help mitigate the risk of mold growth.
