Fig. 7: Efficiency of WWTPs for microplastics removal.
From: Longitudinal study on the multifactorial public health risks associated with sewage reclamation

Removal efficiency (%) of all solid particles (P) and microplastics (MPs) between influent and effluent samples collected from six different WWTPs (P1-P6) after both pre-treatment protocols. Total Particles (T) and Sieved > 300 µm (S).
