If people experience health reactions while indoors, indoor pollutants may be the cause.

These include mould spores and bacteria as well as chemical solvents, particles, fibres and allergens. In such cases, a precise pollutant analysis is advisable in private premises and required in commercial premises. Analysis provides the basis for targeted action; without it, an assessment cannot be made because pollutants can occur in areas that are not visibly apparent, particularly in indoor air.

Indoor air measurements or other appropriate samples are therefore taken first to assess the situation. If elevated values are found, the emission sources must be identified: the materials or treatments responsible for the contamination. Sampling and laboratory analysis must follow standardised procedures for which recognised guidelines are available.

It is particularly important that those affected receive a clear assessment of the possible health risk and the symptoms they have experienced. A technically sound laboratory report alone is of little use if a non-specialist cannot understand it. Individual advice and appropriate solutions therefore always come first for us.

As experienced experts in hazardous materials in buildings and indoor environments, we examine indoor air, household dust or suspect materials for chemical and biological pollutants, depending on the situation and the question being investigated. We then identify the sources associated with the contamination found. The expert report summarises the results, assesses the risk to residents or employees and recommends measures to reduce or eliminate exposure.
