📚As all of us more or less know, MPs/NPs are formed, among others, after the degradation of single-use plastic products, by UV light exposure ☀️ and/or mechanical stresses. There is also the potential for particles to be released directly, without the need for material fragmentation, as research has shown that materials (such as 😷) can have a significant amount of loosely attached plastic particles.
During my STSM journey, we’ll try to investigate what is actually released from single-use plastics into the water, after extensive weathering conditions. The plastic leachates are examined with several characterization and analytical techniques.
🔬Today is the turn of dynamic light scattering (DLS) measurements. DLS has been extensively used for the measurement of NPs and of particles within the size range 800 nm-5 µm.
Herein, the several prepared aqueous samples containing plastic leachates were analyzed by DLS to examine the size of the released particles after weathering.
