When a raindrop hits a water surface or a gas bubble bursts, a complicated fluid mechanical mechanism leads to the creation of a multitude of tiny droplets which are ejected into the surrounding air. These droplets can act as carriers for microplastic particles which were initially suspended in water. Since both rain and bursting gas bubbles are extremely frequent processes in natural and technical systems such as oceans, ponds or wastewater plants, they represent a potentially highly relevant migration path from the hydro- to the atmosphere. The aim of the present project is to obtain a detailed mechanistic understanding of this process based on a combination of model experiments and computer simulations.
