Current methods for measuring microplastic fibres (MPF) are cumbersome, time consuming and unscalable routine high throughput analysis. This study reports a method rapidly extracting, quantifying analysing MPFs in laundry wastewater with several key improvements which vastly enhance overall efficiency scalability of FT-IR surveying is employed as preliminary step analysis to quickly determine what polymers present sample prior fluorescence treatment. Using random quadrating, whole 25 mm filter membranes were surveyed <30 min recovery rates. In industrial samples, polyester was the most common MPF, however acrylic, nylon, cotton rayon all ubiquitous. The also demonstrates that an excitation wavelength 365 nm optimal fluorescing PET like stained Nile Red, but not 495 nm, commonly used Finally, custom ImageJ macro written automatically enumerate describe on using just single stitched image. few seconds, concentrations up 40,000 fibres/L analysed samples lower particle size limit 20 μm. highlights need more optimised scalable workflows maintain levels reliability accuracy.
