Herewith we employ Raman imaging to directly visualise microplastics and nanoplastics which are released from the trimmer lines during lawn mowing. The signal-noise ratio of Raman imaging is significantly increased by generating an image from hundreds or thousands of Raman spectra, rather than from a single spectrum, and is further increased by combining with the logic-based and PCA-based algorithms. The increased signal-noise ratio enables us to capture and identify microplastics and particularly nanoplastics, including plastic fragments or shreds (with diameters \/ widths of 80 nm \u2013 3 \u00b5m) and nanoparticles (with diameters of &lt; 1000 nm) that are released during the mimicked mowing process. Using Raman imaging, we estimate that thousands of microplastics (0.1\u20135 mm), and billions of nanoplastics (&lt; 1000 nm), are released per minute when a line trimmer is used to mow lawn. Overall, Raman imaging provides effective characterisation of the microplastics and is particularly suitable for nanoplastics.<\/p>\n<h2>Graphical Abstract<\/h2>\n<p><img decoding=\"async\" loading=\"lazy\" class=\"alignnone size-full wp-image-10995\" src=\"https:\/\/recedebioplastics.com\/wp-content\/uploads\/2022\/11\/1-s2.0-S0304389421027576-ga1.jpg\" alt=\"\" width=\"301\" height=\"237\" \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>We came across a very interesting article that ties into our Sustainaline trim line product from Weed Recede.
