In the framework of the Climate KIC programme "Pioneers into Practice" we had an opportunity to host Ms. Barbara Massalska at LIAE in October. Barbara is an organic geochemist working at the Polish Geological Institute. Her current research involves the reconstruction of primary producer communities in the Zechstein Sea (Permian) based on organic geochemical indices and biological markers. Microplastic pollution studies has been in her circle of interest already a while ago. At the LIAE Barbara acquired sampling, preparation and analysis techniques used to study microplastic pollution for the assessment of freshwater ecosystems status and changes. We wish Barbara neverending success in applying the gained practical skills at future studies!
