Response to Comment on “Plastic Teabags Release Billions of Microparticles and Nanoparticles into Tea”

We thank Busse et al. (1) for their interest in our paper describing the release of micro- and nanoparticles from plastic teabags. (2) The objective of our study was to determine whether plastic teabags could release micro- and/or nanoplastics and to estimate the numbers of particles released. In accordance with our findings, Busse et al. (1) confirm that plastic teabags release plastic particles. However, as they used different experimental approaches and analytical techniques, the results of the two studies can not be compared. Here, we address the specific points raised by Busse et al. (1) and provide additional details to address misinterpretations of our work.
