The Study about Occurrence of Substances of Concern in Baltic Sea Region Buildings, Construction Materials and Sites

13 May 2025
Technical details

The study focuses on understanding hazardous substances in urban environments, especially how building materials might contribute to pollution indoors and outdoors. It covers five cities in the Baltic Sea Region: Tallinn, Helsinki, Turku, Västerås, and Stockholm. Researchers conducted targeted screening for pollutants in five different matrices: construction materials, stormwater, indoor dust and air, and residential wastewater. The main goal is to document where these hazardous substances are present and identify their sources within the partner municipalities of the NonHazCity3 project. Essentially, it provides a clear picture of where hazardous substances are found in urban areas and traces their origins.
