“…We recently proposed to investigate the potential of a commercial device for a direct detection in water of MPs [4], mainly for industrial applications. We observed MPs very clearly and we were able to provide a method of prescreening using ultra-high resolution imaging cameras.…”

We use hyperspectral imaging to identify the plastic types constituting mixtures of microplastics directly in water. For the current study we used known microplastics made by milling original pristine plastic sheets and mixed them in water. Using database information and spectral information measured on those pristine plastic we created a decision table enabling the identification. This technique is used under these conditions paving a way towards on-field and in-line measurements.
