Article Snippet: How the data were acquired , Rheological measurements were performed using Physica MCR 301 rheometer with parallel plate measuring geometry with a TrueGap® option (plate diameter 50 mm, 1 mm gap) and built-in Peltier device enabling precise temperature control. Images of particles settling in a transparent column were captured using Basler acA2500–60um camera with Schneider-Kreuznach macro lenses Componon 2.8/28–001 with aperture 3.5 F; 6 mm extension tube; images were recorded on a hard disk using digital video camera recording software StreamPix®. Images were pre-processed and processed using ImageJ and Matlab® Image Processing Toolbox to obtain data on temporal variation of particle centroid position..

Article Snippet: Data collection , Particle settling experiments were performed in a tank (0.5 m high, 0.11×0.11m inner dimension) with transparent walls and backlight. Basler acA2500-60um camera with Schneider-Kreuznach macro lenses Componon 2.8/28–001 with aperture 3.5 F mounted perpendicular to the front wall of the tank was used to capture images of particles settling in test solutions. Data were recorded by digital video camera recording software StreamPix®. ImageJ and Matlab® Image Processing Toolbox® enabled data pre-processing and processing, and next the assessment of time-resolved microplastic centroid position and orientation. Samples of test solutions (about 10 ml) were taken to measure rheological properties using Physica MCR 301 rheometer with a coaxial cylinder measuring geometry and a built-in Peltier device for temperature control..
