Microalgae sticks to microplastics and transports them to the seabed. "Science for Environment Policy"
Résumé
Fragments of microplastics are readily incorporated into groups of microscopic algae, altering the rate at which the plastics move through seawater, a recent study has found. In laboratory tests, polystyrene microbeads, which usually sink to the bottom of seawater at a rate of 4mm a day, sank at a rate of several hundreds of metres a daywhen part of microalgae aggregates.
