We very much appreciate scientific discussion of the article published in Scientific Reports by Deng and co-workers (Deng et al. 2017). The correction of Fig. 2 from the latter publication underlines the usefulness of scientific discourse to improve the quality of published data.
Dr. Deng and Dr. Zhang have responded to a recent letter here in Archives of Toxicology (Braeuning 2018) with a statement focused on the issue of microplastic uptake into the tissue and, to a lesser extent, also dealing with the relevance of certain endpoints to assess putative harmful effects of microplastics. A recent review by the European Food Safety Agency (EFSA 2016) is criticized in matters of its conclusions regarding oral bioavailability of plastic microparticles. The authors of the EFSA review article were aware of previous literature, e.g. the papers now cited by Deng and Zhang (2019), suggesting translocation also of very few larger microparticles across the intestinal barrier. Nonetheless, EFSA...
