Why is laboratory analysis important during environmental investigations?

Laboratory analysis provides objective evidence about contaminants present in a building or workplace environment. While site inspections and monitoring equipment may indicate potential issues, laboratory testing confirms the type and level of contamination present.

For example, mould spores collected during an investigation can be examined under a microscope to identify the species and concentration present in the indoor environment. 

This information helps environmental consultants determine whether contamination levels are typical or elevated and supports decisions about remediation, ventilation improvements, or further monitoring.
