Building pollutants

Pollutant discovery and establishment of a campus-wide harmful substance register

From 1950 to 1990 in particular, substances and additives were used in the construction industry which are now known to be harmful to human health. The use of "dirty" building materials such as PCBs or asbestos is largely prohibited today.
Still, contaminated sites in buildings can be a problem because the materials last a long time. Under certain circumstances, they can evaporate or be released during construction work.
With this homepage, the University of Hohenheim would like to document such sites, inform about precautionary measures, and show what is being done to make these contaminated sites safer.

Remarkable pollutant finds in recent years

The process was triggered by the discovery of PCB-bearing grout in the office rooms of the East Yard of the Hohenheim Palace in spring 2019. In the years 2009 and 2016 old problems with the buildings and the way these were dealt with surprised members and management of the University:

PCB discovery 2019 in Palace (in process):
On 10 May 2019 the university obtained the examination result of a building materials analysis of the East Yard of the Palace with PCB values that it considered to be highly critical. more

Previous asbestos problem in the Biology building (renovation completed):
In March 2016, improper construction work released asbestos in the Biology building. The people in the building were exposed to an unknown asbestos concentration. Meanwhile, the renovation has been completed. more

Earlier PCB in lecture halls 4 and 5 (renovation completed):
In autumn 2019, the university was informed about high PCB values in the room air of lecture hall 4 in the Palace and closed it immediately. Earlier, there were measurements by the University Building Office in the years 2003, 2008, and 2009 about which the University was not informed. Meanwhile, the renovation has been completed. more

Use for campus-wide pollutant screening

Since spring 2019, the university management has also been advocating for a campus-wide pollutant screening of harmful substances in buildings. The focus is on the pollutants PCB, PCP, asbestos, and synthetic mineral fibers. This was triggered by years of health hazards to several university members caused by PCB-containing building materials in the Brand wing of Hohenheim Palace, of which the affected persons and the university management were informed in spring 2019.
The University finds itself in the difficult situation of having to rely on the cooperation of the Ministry of Finance, which is the owner of the building and manages the campus buildings via its non-university subsidiary, the Stuttgart-Hohenheim University Building Authority, for all issues relating to its buildings.

The University of Hohenheim has commissioned 100 air measurements to speed up the screening and subsequent removal of harmful substances. These measurements will now be carried out step by step and on an as-needed basis. The measuring locations and results will be published here.

In the future, even in the case of smaller construction maintenance measures in buildings with suspected pollutants, an analysis of harmful substance will be carried out by an expert before the start of the construction measure. Previously, this was only done for larger renovations.
