Understanding Mould
One of the most common questions received by Vertex Analytics laboratory revolves around the presence and treatment of mould. In this article, we’ll explore the intricacies of mould assessment, mould testing and why these processes are essential.
Mould Overview
Mould growth in indoor spaces is a multifaceted problem, impacting both building structures and occupant health. The term “mould” encompasses various fungi species such as fungus, mildew, and sooty mould. Addressing mould testing queries can be challenging due to this terminology, but all these terms refer to fungi capable of colonising organic materials like fabrics, wood, carpet, and upholstery.
- Mould Example: The image above captures a colony growing within carpet fibres. If left undetected, this colony can cause permanent staining and damage. In severe cases, structural materials like timber may be compromised.
Once mould is established, it rapidly produces spores, contaminating air and surfaces. These spores can promote dust mites, further degrading indoor air quality.
- Mould Example: This image shows how mould spores can also cause the growth of allergens, causing dust mites.
Health and Allergenic Potential
Exposure to mould spores and fragments (hyphae, detritus) can cause various health issues, from mild allergies to severe respiratory problems. Common symptoms include:
- Allergy-like reactions (sneezing, itchy eyes)
- Airway inflammation
- Asthma exacerbation
- Immune system sensitisation
Certain moulds produce mycotoxins, which can lead to serious health problems, especially for individuals with weakened immune systems or chronic lung conditions. According to the World Health Organisation, damp and mouldy environments increase the risk of respiratory symptoms and infections.
The Need for Mould Testing and Mould Assessment
One of the significant challenges in managing indoor mould is the lack of specific legislation in Australia. Unlike asbestos, there are no clear standards for acceptable mould levels. Professionals often use comparative measures, ensuring indoor mould levels do not exceed outdoor levels. Surfaces should be free of active mould colonies and excessive spore counts, but such assessments depend on expert sampling and analysis. The absence of regulatory guidelines complicates remediation efforts, insurance claims, and legal actions related to mould-induced health issues.
Adding to this complexity is the variability in mould types and their associated health risks. Without standardised guidelines, identifying and categorising these moulds becomes more challenging, making it difficult to assess the severity of contamination accurately. This further stresses the importance of professional mould assessment and mould air quality testing by experts. These tests not only provide a clear picture of the extent of mould presence but also guide appropriate remediation measures. Accurate mould inspection reports are crucial for property owners, ensuring safety and compliance and helping navigate potential legal and financial implications. Until regulatory frameworks are established, professional mould exposure testing remains a vital tool in managing indoor air quality and safeguarding health.
Despite this, occupants or site managers can perform their own mould air quality testing and mould exposure testing to confirm suspected mould problems.

Conclusion
Mould in indoor environments is a significant issue, affecting both structural integrity and occupant health. The lack of specific legislation in Australia makes mould assessment and remediation challenging. Until comprehensive regulations are established, contacting Vertex Analytics for mould inspection reports and mould exposure testing is a practical approach.
