This work presents preliminary results from a survey that includes both the literature and the so-far established European legislation
concerning microplastics (MPs) sampling procedures. Our findings suggest that even though the MPs sampling and collection
methods can significantly affect the result of their quantification and identification, a clear harmonization in microplastics sampling
protocols still does not exist. Secondly, we will describe two different possible sampling approaches. The first includes the use of the
automatic on-site sampler which is already installed at the outflow of the Thessaloniki Wastewater Treatment Plant (TWWTP). The
second possible sampling scenario includes the construction of a mechanism that could immerse a custom-made screening device at
the effluent channel for a certain time period. The advantages and disadvantages between the two approaches and the next steps
are presented and discussed.
