Research Projects
N-nitrosamines, along with other pollutants, have become a cross-sectoral, persistent, and important health issue in various areas of occupational, environmental and product protection in recent years. They are among the organic nitrogen compounds with a high carcinogenic potential. The aim is to provide a new method with which, firstly, nitrosamines in air and, secondly, also in other matrices can be measured more sensitively than before with simultaneous robustness and result validity.
Project management at the H-BRS
Prof. Dr Michaela Wirtz
The occurrence of N-nitrosamines is an important public health issue. Due to their good water solubility, they enter the aquatic environment via industrial and municipal input pathways. For companies, they are a major problem due to their carcinogenic potential, diversity and versatile occurrence due to frequent formation in technical processes. The aim is to develop a sensitive, sufficiently selective, economical, and on-site analytical method with sample preparation that can be automated as much as possible.

Publications
In addition to the publications listed in the publications list, a wide range of chemical and analytical scientific issues were evaluated in the years from 2006 to 2016, however, these were not published in scientific journals due to the protection of industrial interest.
