Optical identification of car tire particles on soil using fluorescence lifetime imaging microscopy
AI summary Read the abstract
This study applied fluorescence lifetime imaging microscopy combined with image processing algorithms to optically identify tire wear particles on soil. The technique successfully detected and distinguished tire rubber microplastics from soil matrix, offering a non-destructive method for monitoring this significant microplastic source.
Tire wear is one of the major contributors of environmental pollution by microplastic. FD-FLIM in combination with an image processing algorithm are successfully applied to detect tyre wear on soil.

Analysis of tire wear particles in soil samples from roadside using TED-GC/MS
AI summary Read the abstract
Researchers developed and applied a thermal desorption gas chromatography mass spectrometry (TED-GC/MS) method to analyze tire wear particles in roadside soil samples, addressing the challenge that fluorescence interference makes conventional spectroscopic methods unreliable for tire rubber detection. They confirmed the presence and quantified tire wear particles in soil from roadsides in Germany. The study advances analytical methods for one of the most significant but undercharacterized microplastic sources in the environment.

Environmental occurrence, fate, impact, and potential solution of tire microplastics: Similarities and differences with tire wear particles
AI summary Read the abstract
This review examines tire microplastics, one of the most abundant types of microplastics in the environment, which come from tire wear on roads, recycled tire rubber, and tire repair dust. These particles carry a complex mix of chemicals including heavy metals and organic pollutants that can harm aquatic and soil organisms. Since tire microplastics end up in waterways and soil near roads, they represent a significant but often overlooked source of human microplastic exposure.
