Summary: This study aims to analyze tire wear particulate matter (TWP) from tread rubber with different formulations and compare the concentration of TWP with different wear devices. The TWP concentration was higher when natural rubber (NR) was solely used as the tire tread material, but decreased when NR was mixed with butadiene rubber. Changing the type of carbon black (CB) also reduced the amount of TWP in the 2.5 μm size range. The TWP concentration increased with increasing speed and vertical load, and similar trends were observed in tests using different wear devices.

Summary: Brake wear emission is becoming a significant contributor to vehicle-related particulate matter, but there is still limited knowledge about its emission features and determining factors. Experimental results show that separating brake pads and discs releases more particles, larger speed reduction exponentially increases emissions, and the enhancement of nanoparticles is related to the evaporation of organic constituents in the pads. The emissions from front and rear brake assemblies are not consistent with braking torque distribution due to different braking pressures. A parameterization scheme based on kinetic energy loss is developed to predict the variation of brake wear particle (BWP) emissions under real-world driving conditions.

Summary: A method of capturing TWPs in tunnels to prevent their release into the environment was proposed and verified through experiments, showing a capture efficiency exceeding 50%. The optimal capture ratio occurs at 60 km/h and is mainly determined by the pressure difference between tunnel ends, with health-related TWPs smaller than 10 ?m being the main source captured. This method provides guidelines for alleviating pollution caused by TWPs.

Summary: Microplastics, as emerging anthropogenic stressors, pose potential threats to ecosystems and human health. While the presence of microplastics in water is well-documented, their distribution in the air is limited. This study investigates the occurrence of microplastics in suspended particulate matter in Tempe, Arizona, and finds that microplastics are present in all collected samples, ranging in concentration from 0.02 to 1.1 microplastics/m3 with sizes ranging from 5 to 5000 μm. Fibrous microplastics are the most prevalent, accounting for over 82% of the microplastics. The study also characterizes the chemical composition of the airborne microplastics using micro-Raman spectroscopy, revealing a variety of polymers, with polyvinyl chloride being the most abundant.

Summary: The study found that a single two-week calibration is insufficient for accurate NO2 measurements due to the variable environmental conditions. Temperature, relative humidity, and ozone were identified as critical parameters that require correction in the calibration model. To address this, a period-specific calibration model was developed and re-trained every six weeks. This improved calibration significantly enhanced sensor performance compared to the manufacturer's calibration, resulting in more accurate NO2 measurements in a sensor network.
