The complex, varied composition (i.e., rubbers/elastomers, carbon black, fillers, additives, and embedded road materials) wide density range of tire wear particles (TRWPs) present challenges for their isolation identification from environmental matrices. Reliable quantification is important understanding the fate potential adverse effects TRWPs. To address monitoring needs, work adapts a series steps methods commonly applied microplastic analysis single-particle-level enumeration TRWPs samples. We method performance two-stage separation with saturated NaCl sodium polytungstate to isolate sediment matrices, compatibility microrubber reagents used digestion use elasticity heat resistance observations differentiate bitumen particulates, which are visual interference. found that alkaline digestions (NaOH KOH) compatible microrubbers, but hydrogen peroxide hypochlorite can cause lose flatten or break when probed. adapted were dust samples, subset identified was qualitatively confirmed by both scanning electron microscopy pyrolysis-gas chromatography-mass spectrometry. Further, compilation aspect ratio measurements between 63 500 μm (N = 780) isolated urban sediments shows diversity TRWP shapes in environment.

Microplastic (MP) pollution has garnered widespread attention because of its negative effects, even in the most remote areas Earth. However, research on MP deposition deserts, which account for 45% Earth’s total land area, remains limited. Desert environments, characterized by large temperature fluctuations, high ultraviolet radiation, and strong winds, accelerate degradation, aging, wind erosion, deposition, migration microplastics (MPs). In desert regions, MPs originate primarily from human activities, such as tourism waste, agricultural mulch residues, artificial water storage systems. Additionally, transport, entrainment, atmospheric wildlife further influence abundance these areas. As soils intensifies, it negatively affects local microbial activity, crop yields, reproduction rare wildlife, climate. response, mitigation strategies, biodegradation, organic alternatives, wasteland transformation, have been proposed. challenges remain, including a lack specific data limited economic incentives environmental protection measures. Drawing existing research, this paper provides comprehensive summary main sources areas; factors their fate; detrimental effects ecosystems (including microorganisms, animals, plants, climate); current response Valuable insights are extracted available data, highlighting status offering useful reference future area.
