Summary: Air pollution from road traffic is a significant health concern due to both exhaust emissions and non-exhaust emissions, with limited data on the toxicity of the latter. This systematic review aims to provide an overview of the biological effects of non-exhaust emissions, focusing on the toxicity of Tire and Road Wear Particles (TRWP) in mammalian models. A bibliographic search yielded 22 relevant papers, indicating a limited understanding of TRWP toxicity in mammalian models. The review highlights oxidative stress and inflammation as the main mechanisms underlying TRWP toxicity.

Summary: The study analyzed the mass fraction of the finest fractions of road dust from highways and expressways with asphalt and concrete surfaces. It was found that concrete pavement is less susceptible to abrasion than asphalt pavement. Sound-absorbing screens accumulate fine road dust, while strong air drafts remove smaller particles from the vicinity of the road. The mass fraction of particles smaller than 100 μm in road dust ranged from 12.8% to 3.4% for asphalt surfaces and from 12.0% to 6.5% for concrete surfaces.

Summary: Ship emissions of nitrogen and sulfur contribute significantly to coastal deposition and acidification/eutrophication near the Baltic Sea. Implementation of NECA and SECA can decrease nitrogen impacts, but eutrophication effects still persist. Geographically, the impact of shipping emissions is unevenly distributed within countries, with coastal areas experiencing higher effects than national summaries suggest.

Summary: This study investigated PM10 emissions generated from brake wear of passenger cars during different driving cycles using a finite element analysis approach. The results showed that the proposed simulation approach could predict PM10 emissions from brake wear, and there was a gradient rise in pad wear from the inner to outer radii. Furthermore, reducing the frequency of high-speed braking was found to be an effective way to decrease PM10 emissions.

Summary: There is limited data on vehicular emission characterization and the contribution of non-exhaust vehicular emissions to ambient particulate matter in real-world driving conditions in India. This study aims to analyze the trace elements, metals, and black carbon in PM2.5 and PM10 from light-duty vehicles (LDVs) and mixed vehicular fleet with heavy-duty vehicles (HDVs) through road tunnel measurements. Real-world emission factors (EFs) were estimated, and source apportionment was conducted to identify the plausible sources of road traffic emissions. The study highlights the need to regulate non-exhaust vehicular emissions.

Summary: In a novel approach, the combination of emission and air pollution aspects is used to identify vehicles that do not impact air quality. This is done by defining the term "Zero-Impact Emissions" and developing a compliance test matrix with various scenarios and boundary conditions. Simulation models are then used to test different scenarios for gasoline and diesel vehicles, showing that achieving Zero-Impact Emissions depends on the specific boundary conditions.

Summary: This paper examines the relationship between vehicle weight and PM10 and PM2.5 emissions from electric vehicles and traditional internal combustion engine vehicles. The outcome is dependent on the use of regenerative braking in electric vehicles relative to friction braking. Overall, there will be modest changes to the total local emissions of particles from a passenger car built to current emissions standards.

Summary: An increasing number of motor vehicles are causing negative environmental impacts due to exhaust gas emissions. This study focuses on the emissions produced by exhaust gases after a road vehicle starts. The research results show that emissions are lowest when the vehicle starts downhill and highest when it starts uphill. This research helps to quantify data and provide solutions for reducing emissions.

Summary: This review examines the current state of heavy metal contamination in road dust in different cities around the world. It evaluates the ecotoxicological and human health risks associated with heavy metal exposure. The findings show significant variations in contamination levels among cities, countries, and continents. Australia and Asia are identified as the regions most susceptible to heavy metal pollution, while cities in Europe, Africa, and America show no significant risk.

Summary: This study found that road traffic contributes mainly to the ambient levels of airborne particulate matter (APM) through exhaust emissions and tire/brake wear, accounting for 3.4% and 17% of PM10 respectively. Additionally, road dust and crustal material also contribute to PM10, making up 18% in total, with 7.3% being contributed by traffic resuspended dust. Therefore, policies aimed at controlling traffic-derived PM10 pollution should adequately address non-exhaust emissions.

Summary: This study evaluated the hourly particle number size distributions (PNSD) from 26 sites in Europe and 1 in the US, focusing on urban background (UB) and traffic (TR) sites. The objective was to describe the characteristics of urban ultrafine particles (UFP) in Europe. The results showed variations in PNC and BC across different regions and site types, with traffic emissions being a major contributor. The study emphasized the need for specific monitoring of PNSD and measurements of <10 nm PNC for assessing the health effects of nanoparticles.

Summary: This study analyzed the variability and sources of equivalent black carbon (eBC) mass concentrations in urban Europe, emphasizing the need for harmonization of eBC measurements. The results showed a decreasing trend of eBC mass concentrations from traffic sites to urban background sites to suburban sites to regional background sites. There was also a clear decreasing trend in eBC concentrations from Southern to Northern Europe. Furthermore, the study revealed significant spatiotemporal heterogeneity in eBC concentrations and variable contributions of different pollution sources.

Summary: This literature review summarizes toxicological and epidemiological studies of ultrafine particles (UFPs) from different transport modes, including vehicle exhaust, non-exhaust, shipping, aviation, and rail. The results suggest that particles from both fossil and biodiesel sources exhibit toxic effects, with impacts on the lung, cardiovascular system, and brain. Further research is needed to better understand the relative toxicity of UFPs from different transport modes and their implications for health risk assessment.

Summary: Unconventional oil and natural gas development (UOGD) in the United States has expanded rapidly in recent decades, raising concerns about its impact on air quality. This study conducted extensive air monitoring during the development of several large well pads in Broomfield, Colorado, providing a unique opportunity to examine changes in local air toxics and VOC concentrations during well drilling and completions and production. The study identified significant increases in VOC concentrations during drilling operations, highlighting the importance of emissions from synthetic drilling mud.

Summary: This study investigated the changes in nitrogen dioxide (NO2) air pollution levels and their disparities in California, U.S. during the pandemic of coronavirus disease 2019 (COVID-19). The results showed a decrease in NO2 concentrations, especially in urban and high-traffic areas. However, socially vulnerable populations still experienced higher levels of NO2 exposure. The study suggests that reducing NO2 disparities, particularly racial inequity, can be achieved through continued regulatory actions targeting traffic-related NOx emissions.

Summary: This study investigates the chemical composition and oxidative potential of PM10 particles in the Po Valley, Italy, and demonstrates the impact of high levels of atmosphere ammonia. The rural area had significantly higher ammonia concentrations compared to the urban site, resulting in higher levels of secondary inorganic aerosol. Although the SIA components did not contribute significantly to the PM10 oxidative reactivity, they were correlated with the oxidative potential measurements. This suggests that the contribution of SIA to PM oxidative toxicity cannot be ignored.
