This article discusses common indoor molds that produce mycotoxins and the materials on which they are commonly found. The general public thinks that black indoor molds are toxigenic because of the publicity that Stachybotrys chartarum (a.k.a Stachybotrys atra in the old literature), a black mold, received in the recent years. However, the colour of the indoor […]

Interpreting Numerical Data of Viable Airborne Mould Samples
Another article on airborne mould samples provides guidelines for interpreting numerical data of viable air samples. To see the guidelines for non-viable air samples click Guidelines for Interpreting Non-viable Air Samples. The guidelines may be used to decide whether further investigations are required after initial investigations. As was indicated in the last Issue, numerical laboratory […]
How To Interpret Laboratory Results for Airborne Fungal (Mould) Samples
Laboratory results for airborne mould and bacteria concentrations can be difficult to interpret for two major reasons. Maximum exposure limits have not been set Currently, there are no set maximum exposure limits (MELs) or threshold level values for airborne indoor mould and bacteria concentrations. Setting MELs would be difficult for reasons which include limitations in […]
Guidelines for Interpreting Numerical Data of Non-viable (Spore Traps) and Viable Airborne Mould Samples
In this article we discuss additional guidelines for interpreting numerical data for viable and non-viable airborne mould samples. The guidelines may be used to decide whether further investigations are required after initial investigations. However, numerical laboratory results cannot be used as the primary determinant of whether there is a mould problem but should always be […]
Your Classification Guide to Common Mold Types
Molds (also spelled “moulds”) are simple, microscopic organisms that can grow virtually anywhere, both inside buildings and outdoors. Mold colonies can grow inside damp or wet building structures. And mold spores are a common component of household and workplace dust. Health effects from exposure to mold can vary greatly depending on the person and the […]
