When gloves rub against surfaces, they leave behind sticky bits that break into tiny pieces smaller than a tenth of a human hair. These bits stick to everything and are hard to tell apart from real plastic pollution when scientists try to spot them with light-based tools.
Most probable mechanism
When gloves made with stearate-based compounds are rubbed against surfaces, tiny sticky residues break off into extremely small pieces. These pieces are so small and light that they easily stick to other surfaces without needing moisture, and they are hard to tell apart from real plastic pollution when scientists try to detect them using light-based tools.
Stearate-based compounds from glove materials adhere to dry surfaces through weak intermolecular forces during physical contact.
Mechanical friction during glove use causes these adhered residues to fragment into particles smaller than 10 micrometers due to their low cohesive strength and high surface energy.
Particles in the sub-10 µm range remain airborne or surface-bound under ambient conditions due to low gravitational settling and high electrostatic retention.
The chemical composition and optical properties of these fragmented stearate particles closely mimic those of synthetic microplastics, leading to spectral signal overlap in analytical detection systems.
