We demonstrate that direct imaging is a powerful tool for the detection and recognition of microplastics in water, even in case of complex matrices. We use a commercial high-resolution imaging device (Valmet FS5, Valmet Oy.) originally developed for the observation of wood fibres and particles in papermill pulp samples. We show how to discriminate microplastics from other particles in suspension in real water samples. We show differences between several common plastic types in homemade samples.
