These days, we live in a so-called plastic-society: most of the products are made of or are packaged with plastics. This is also reflected in the increasing plastic production with 311 million tonnes in 2014 worldwide (PlasticsEurope, 2015). Regarding their size, plastic particles can be divided into macro-, meso- and microplastic, whereby the focus of my PhD will be on microplastic particles <5 mm (Arthur et al., 2009; European Commission, 2013). Depending on their origin, microplastics can be categorized in primary and secondary microplastic. Secondary microplastics, accounting for approximately 80% of all microplastics, are a result of the breakdown of larger plastic items caused by weathering via UV-radiation or mechanical stress (Browne et al., 2007; Cole et al., 2011). Due to the breakdown of larger particles, secondary microplastic particles are much more bioavailable for aquatic organisms. When covered with biofilm small plastic particles can sediment and become available for nematodes in fine sediments.
During my PhD I would like to investigate the ingestion, egestion and the effects of microplastic particles on the nematode speciesCaenorhabditis elegans by conducting ingestion and egestion experiments, chronic toxicity tests according to the specifications of the ISO 10872 guideline and life-cycle experiments.
