Joint committee "Chemistry, Air Quality, Climate" from ProcessNet / GDCh / DBG

The joint committee ?Chemistry, Air Quality and Climate? (GA-CLK) sees itself as an expert group for chemical and chemical-technical aspects of Atmospheric Chemistry chemistry, air quality and climate change. In connection with scientific questions and environmental and regulatory measures, the committee pursues the following objectives:

     

  • Discussion and evaluation of the state of research and development in specific subject areas of CLK
  • Identification of knowledge deficits and, if necessary, need for action
  • Launch of R&D initiatives to remedy deficits
  • Elaboration of statements on regulatory measures in the areas of CLK

The working committee is interdisciplinary; however, there is a focus on atmospheric sciences. He does not do research himself, but discusses and evaluates research. Its members come from university institutes and other research institutions, from environmental authorities and from industry. The current chair is Prof. Dr. Peter Wiesen (Wuppertal). The working committee bundles the expertise and interests of several scientific societies (ProcessNet, GDCh and DBG) and is therefore integrative and not in competition with other bodies of these societies. A particular concern of the committee is the processing of topics that are of social and / or industrial importance. The core of the work is the close interlinking of basic and applied research. The purely academic interest is not in the foreground.

The working committee currently has several main topics that are being worked on in parallel. These include:

1. Atmospheric Chemistry and climate
Atmospheric Chemistry in its entirety and specific aspects of its manifestation in the context of climate change and protection were the core topics of the establishment of the working committee and still determine a significant part of its professional orientation today. The focus is always on the chemical aspects.

2. Urban air quality
In the European Union, air quality is determined by limit or guideline values specified in laws or ordinances. New scientific findings may require a reassessment and changes to the assessment basis. Many guideline and limit values relate exclusively to specific problems such as vegetation protection, the risk of cancer in humans or an official framework for the application of certain measures.

3. Semi-volatile organic compounds
In contrast to chemistry in water, Soil and air, science still has a lot of catching up to do with those substances that switch back and forth between environmental media (so-called multi-compartment substances). Research on the distribution and fate of semi-volatile and, at the same time, persistent (ie poorly degradable) organic substances is particularly complex because they can carry out several cycles through the atmosphere ('grasshopper effect').
