Co-Transport of Tire Wear Particles with Cd2+ and Ni2+ in Porous Media: Impact of Adsorption Affinity and Desorption Hysteresis

The environmental implications of tire wear particles (TWPs) have been extensively studied. One notable concern associated with nano-sized TWPs is their potential role as carriers that enhance the spread of co-occurring pollutants, especially in the context of aging processes. This study demonstrate...

Zusammenfassung:	The environmental implications of tire wear particles (TWPs) have been extensively studied. One notable concern associated with nano-sized TWPs is their potential role as carriers that enhance the spread of co-occurring pollutants, especially in the context of aging processes. This study demonstrated how exposure to acid, ultraviolet (UV) radiation, or ozone (O 3 ) induced alterations in the physico-chemical properties of TWPs, consequently increasing their mobility within saturated sand environments. In cotransport cases, both original TWPs and aged TWPs inhibited the transport of Cd 2+ and Ni 2+ in different degrees, whereas no obvious changes in their intrinsic mobilities. The contaminant-mobilizing ability of TWPs followed the order of original TWPs/UV-TWPs
