Detection of microplastics in marine sediments of the German Coast via FT-IR spectroscopy Lorenz, Claudia (VerfasserIn) Karsten, Ulf , 1960- (AkademischeR BetreuerIn) Gerdts, Gunnar , 1960- (AkademischeR BetreuerIn) Universität Rostock (Grad-verleihende Institution) Universität Rostock Mathematisch-Naturwissenschaftliche Fakultät (Grad-verleihende Institution) Text theses Text Hochschulschrift 2014 2014 eng electronic resourceremoteComputermedienOnline-Ressource1 Online-Ressource Applying a newly developed method consisting of an extraction using the Munich Plastic Sediment Separator (MPSS), sample purification through enzymatic digestion and spectroscopic analysis via micro Fourier transform infrared imaging (µFT-IR) five North Sea sediment samples (two beaches, Sylt and three sublittoral, German Bight) were investigated for their microplastic load. The encountered abundance of microplastics < 500 µm ranged from 34 to 74 particles kg^-1 dry weight sediment. Furthermore, eleven different types of plastic polymers could be identified, with PP, PE and PS being prevalent.<eng> Claudia Lorenz Masterarbeit Universität Rostock 2015 570 http://purl.uni-rostock.de/rosdok/id00000266 urn:nbn:de:gbv:28-thesis2015-0003-6 doi: 10.18453/rosdok_id00000266 oclc: 1057380522 ppn: (DE-627)1030501858
