Summary: This study investigated the refueling emissions from China 6 vehicles equipped with the onboard refueling vapor recovery (ORVR) system and found that they have significantly higher proportions of small alkanes and alkenes (C2-C3) and lower proportions of C6-C8 hydrocarbons compared to vehicles without emission control measures. The market-share-weighting emission factors (EFs) of total hydrocarbons (THCs) and total VOCs for China 6 vehicles indicate a control efficiency of approximately 98.8% compared to vehicles without emission control. The study also developed a high spatiotemporal resolution refueling emission inventory for a typical Chinese city, showing a significant reduction in refueling emissions with the implementation of the ORVR system.

Summary: Hair products application in hair salons is a potential source of volatile organic compounds (VOCs) emissions. A study conducted on 139 representative hair salons and 88 hair products revealed the VOC emission factors for various products. The VOC emissions from hair products application in Beijing increased from 362.77 tons in 2011 to 393.40 tons in 2020. Hair styling spray, hair dye, perm cream, and hair mask were the major contributors to total emissions, accounting for 93.68% together. High VOC emissions were mainly concentrated in six central urban districts. The per capita VOC emissions in 2020 were 0.018 kg VOCs/person/year. Projections suggest that implementing VOC content limit standards for hair products could reduce VOC emissions by 9.72% by 2030 compared to 2020, emphasizing the need for VOC control measures in hair products application.

Summary: CIPP is a plastic manufacturing technology used in the U.S. that has not been evaluated for compliance with federal air pollution laws. The study found that the emissions of VOCs during CIPP manufacturing were not limited to the curing period but also before and after. Styrene and other hazardous air pollutants were emitted. The estimated VOC emissions for styrene CIPPs ranged from 0.9 to 16.6 U.S. tons, and for nonstyrene CIPPs ranged from 0.09 to 1.6 U.S. tons. Low-cost VOC sensors were found to be unreliable for accurately measuring styrene emissions.

Summary: To control the volatile organic compounds (VOCs) species with high ozone formation contribution in two coastal industrial cities in northeast China, the ambient concentrations of 99 VOCs species were measured and monthly anthropogenic VOCs emission inventories were developed. Positive matrix factorization (PMF) model and potential source contribution function (PSCF) were used to analyze the source contribution and location of VOCs sources. The results showed that petroleum industry, organic chemical industry, and mobile vehicle emission were identified as the main sources contributing to ozone formation. Key anthropogenic sources identified include organic raw chemicals manufacturing, structural steel coating, petroleum refining process, petroleum products storage and transport, off-shore vessels, and passenger cars.

Summary: The objective of this study is to incorporate soil hydraulic properties into the erodibility factor (K) of USLE-type models. By modifying and improving the existing equations for soil texture and permeability, the study successfully included information on saturated hydraulic conductivity (Ksat) into the calculation of K factor. Using the Random Forest machine learning algorithm, two independent K factor maps with different spatial resolutions were generated. The results show that the decrease in K factor values has a positive impact on the modeling of soil erosion rates.
