What is the primary role of air sampling in mould assessment?

The primary role of air sampling in mould assessment is to evaluate air quality when no visual sources of mould are found. This technique is critical because mould can be present in air without visible growth or colonies, meaning that assessments relying solely on visual inspections may miss significant indoor air quality issues.

Air sampling enables professionals to collect and analyze airborne spores and other particulates, allowing for the evaluation of mould levels in the environment. This information is essential in determining whether a space is safe for occupancy and in identifying the need for further remediation actions if elevated mould levels are detected.

In contrast, identifying chemical compounds, determining ventilation needs, or establishing noise levels do not directly pertain to mould assessment but rather focus on different aspects of occupational hygiene and environmental health. Therefore, while those tasks are important in their contexts, they do not capture the essence of why air sampling serves a crucial function specifically in mould assessment.
