Moulds and fungi

When moulds and fungi reproduce, they release countless tiny spores that can become airborne. Health problems can arise when large numbers of these spores are inhaled, ingested or come into contact with the skin.

Stachybotrys chartarum (S. chartarum, also known as ‘Black mould’) is a greenish-black mould that grows on material with high cellulose content, such as fibreboard, that has become extremely wet and has remained wet for some time.

While S. chartarum is growing and is still wet, a wet slime covers its spores and prevents the spores from becoming airborne. It is only when the mould dries out and the spores become airborne that they can become a problem.

Those with pre-existing asthma and those with weakened immune systems, as well as infants and the elderly are at the greatest risk. Most people who experience adverse effects associated with mouldy buildings fully recover following removal and clean-up of the mould contamination.
