Tire wear particles (TWPs), as one of pristine microplastics and non-exhaust emission pollutants, have received extensive attention from scholars worldwide in recent years. In the context of the increasing number of related research results, this study evaluated the current status of TWPs research based on bibliometric analysis and meta-analysis and then discussed in-depth the environmental implications involving transport, transformation of released additives in potential and combined pollution with other microplastics in TWPs researches. Results showed that the regional layout of TWPs research was mainly concentrated in Europe and North America, but with specific countries of the United States, Germany, China, the United Kingdom, and Sweden. Thus, Asia and Africa should timely carry out related research on TWPs considering their large vehicle ownerships. In addition, keyword co-occurrence analysis based on CiteSpace showed that biotoxicity, environmental distribution and human health risks are the current research hotspots. Furthermore, the content of TWPs varied greatly by country and environmental media according to the meta-analysis. It is warranted to be urgently investigated on the distribution, quantitative analysis, migration, additives transformation with toxic effects and control measures of TWPs under the influence of various complex factors such as energy innovation and smart driving. The obtained findings can help understand the developing status of TWPs and then promoting their related investigations in future.

This study employed a high-speed rotating crushing process to modify pyrolyzed carbon black (CBp) using self-lubricating and low-friction polytetrafluoroethylene (PTFE). The effects of PTFE content on the dispersion, mechanical properties, wear resistance, and thermal stability of modified PTFE-CBp/natural rubber (NR) composites were investigated. The rotating crushing process from the high-speed grinder altered the physical structure of PTFE, forming tiny fibrous structures that interspersed among the CBp particles.

Concentrations of microplastics are both temporally and spatially variable in streamflow. Yet, an overwhelming number of published field studies do not target a range of flow conditions and fail to adequately capture particle transport within the full flow field. Since microplastic flux models rely on the representativeness of available data, current predictions of riverine exports contain substantial error.

The ecological impact of tire wear particles (TWP), a significant source of microplastics pollution, is increasingly concerning, especially given their potential effects on the health of aquatic ecosystems. This study investigates the size-dependent ecotoxicological responses of zebrafish (Danio rerio) to TWP exposure, focusing on physiological, metabolic, and microbial community impacts over a 15-day exposure period followed by a 15-day excretion period. Through integrated analysis of gut microbiome composition, liver transcriptomics, and host physiological markers, we found that smaller TWP particles (< 120 μm) induced oxidative stress, evidenced by increased SOD and MDA levels, and inhibited growth by reducing body mass and gut length.

Detecting and quantifying tire wear particles (TWPs) in the environment pose a unique environmental challenge due to their chemical complexity. There are emerging concerns around TWPs due to their potential high numbers of particles released, outnumbering microplastics, as well as the leaching of toxic additives such as 6-PPD which has been linked to the death of salmon even when present at very low levels (<0.1 μg/L).

The concentration, character, and distribution of microplastics in coastal marine environments remain poorly understood, with most research focusing on the abundance of microplastics at the sea surface. To address this gap, we conducted one of the first comprehensive assessments of microplastic distribution through the marine water column and benthic sediment during the wet and dry season in the coastal waters of the San Pedro Bay Southern California, USA. Microplastic concentrations in the water column did not vary significantly across season but were significantly higher in nearshore environments and at the surface of the water column.
