Environmental aging and biodegradation of tire wear microplastics in the aquatic environment

Journal of environmental chemical engineering, Journal Year: 2023, Volume and Issue: 11(5), P. 110604 - 110604

Tire wear microplastics (TWM) are formed by friction between tires and road surfaces during driving they belong among the most abundant in environment. However, information about their fate environment is still unknown. The aim of this study was to investigate aging TWM freshwater under controlled laboratory conditions over 12 weeks. development biofilm, changes physical properties chemical composition, leaching biodegradation were followed. results showed colonization surface microorganisms (up 45 mg/g), which, however, began detach from particles after eight weeks, reducing amount biofilm. initially leached zinc organic compounds (expressed as dissolved carbon - DOC), but concentrations low decreased with time. increase DOC observed 10 possibly due decomposition biofilm release matter. Aging resulted density TWM, morphology composition did not change. This confirms biodegradability tests, which no within Overall, indicated that readily biodegradable therefore may accumulate persist aquatic

Tire and road wear particles (TRWP) are continuously formed by automotive traffic on roads. This study reports effects of long-term degradation over 2 years in water soil the presence microbes TRWP cryo-milled tire tread (CMTT). Degradation had little measurable effect physical properties TRWP; a shift towards larger particle sizes was mainly due to mechanical stress from stirring. The total quantified extractables (TQE) 27 chemicals transformation products determined were reduced 90 % CMTT 85 soil. Most this decrease occurs within first months. For both materials, however, speed loss TQE decreased drastically time. Its kinetics approximated two phases 1st order kinetics, resulting half-lives 17 days for diphenylguanidine (DPG) phase 1 520 6-PPD-quinone (6-PPDQ) biodegradation water. soil, tend be clearly longer compared but remained <1000 such as benzothiazole sulfonic acid (BTSA), N,N'-diphenyl-p-phenylendiamine (DPPD) hydroxybenzothiazole (OH-BT).

Review of Health Effects of Automotive Brake and Tyre Wear Particles

Toxics, Journal Year: 2025, Volume and Issue: 13(4), P. 301 - 301

Published: April 11, 2025

Non-exhaust emissions from brakes and tyres are becoming the major transport-related contributor of particulate matter (PM) pollution in cities. Furthermore, tyre microplastics unintentionally released all environmental compartments. The European Union introduced for first time worldwide limits (PM10) (total abrasion mass) with Euro 7 regulatory step. Thus, interest brake particles regarding health impacts has significantly increased recent years. In this review, we summarise studies that assessed impact on human, mammalian, aquatic, terrestrial cells organisms. compared to other sources. We also critically examine sampling methodologies studies.
