Uptake of polymer particles into the gut of exposed daphnids on the example of selected polymers (as indicated below each picture) with different characteristics. All were internalised as visible by the white coloration of the gut. In addition, negative control Tween 40 only is shown (top right). In the lower middle right panel, a daphnia exposed to positive control micronized tire rubber is shown, here black particles are visible, as well as the light green coloration typical for control animals. PA6 exposure without Tween 40 (lower right panel) confirmed that the white coloration is indeed a result of microplastic exposure
