Common contaminants.

Only in a healthy environment can we feel completely at ease. It is important that living and working areas are free from pollutants which can strain the human body and lead to long-term diseases. A comprehensive assessment of pollutants is therefore indispensable for any renovation. For the sake of users’ and construction workers’ health, we must be aware of the risks that can arise in buildings unbeknownst to its occupants. 

Many substances which had been commonly used in former building materials can be harmful to health and cause illness. Lindner’s analytical evaluation of building material samples and room air measurements provides information as to whether the legal limits have been exceeded and a rehabilitation has to be carried out. 

A brief list of the most frequently encountered pollutants are given below. The full list is far longer, so before any demolition work takes place it is essential to involve a certified refurbishment specialist who can classify the risks and requirements for dismantling. Lindner has the personnel and know-how – contact us and let us take care of the assessment, planning, specification and professional execution of your buildings’ renovations.


PCB (polychlorinated biphenyls) are organic chlorine compounds, which are mainly used as plasticizers. Since 2001, their use is prohibited. When the limit of 3,000 ng / m³ is reached, immediate rehabilitation is required as PCB is carcinogenic and can lead to hair loss, liver damage, or damage to the immune system.

Where to find PCB

  • Coated ceiling boards
  • Paints and varnishes
  • Adhesives
  • Jointing compounds
  • Capacitors


PCP or DDT are harmful components that may occur in wood preservatives. Depending on the concentration, these ingredients act as carcinogens. In smaller amounts, they can damage organs or the immune system.

Where to find PCP or DDT

  • Wood fixtures
  • Wall paints


PAHs (polycyclic aromatic hydrocarbons) such as naphthalene or fluorine are often fluorescent and only slightly water soluble. They are carcinogenic because they can react to human DNA.

Where to find PAH

  • Tar
  • Pitch-containing adhesives
  • Bitumen sheets
  • Humidity barriers

Mineral wool

Mineral wool is a material made from artificially produced mineral fibres. This non-combustible insulating material is less harmful than asbestos because it degrades more quickly, but it also has a carcinogenic effect. The mineral wool which we have used since 2000 is completely free from pollutants.

Where to find mineral wool

  • Impact sound insulation
  • Spray insulations
  • Roof extensions
  • Acoustic ceilings
  • Partitions
  • Floors
  • Facades
