Significant decreases in SO2 emissions and enhanced atmospheric oxidation trigger changes in sulfate formation pathways in China during 2008–2016
TL;DR: Wang et al. as discussed by the authors applied the Community Multiscale Air Quality (CMAQ) model coupled with the sulfur tracking model (STM) to quantify sources of atmospheric SO42− in China and their changes during 2008-2016.

Newer Generation of Scooters: Polychlorinated Dibenzo-p-dioxin and Dibenzofuran and Polychlorinated Biphenyl Reductions
Jheng-Hong Chen,Yun Hwei Shen,Hsi-Hsien Yang,Jau-Huai Lu,Lin-Chi Wang,Yen-Kung Hsieh,Chia-Fon Lee,Sheng-Lun Lin +7 more
TL;DR: In this article, the authors used a 100-second model to analyze PCDD/F and PCB emissions and compare the results with previous Tier 3 studies, which showed that de novo synthesis occurred and could be inhibited by the OBD system in Tier 6.
Journal ArticleDOI
Estimation of secondary PM<sub>2.5</sub> in China and the United States using a multi-tracer approach
TL;DR: Wang et al. as discussed by the authors developed a new method, named Multi-Tracer Estimation Algorithm (MTEA), to identify the primary and secondary components from routine observation of PM2.5.
Journal ArticleDOI
A license plate recognition data to estimate and visualise the restriction policy for diesel vehicles on urban air quality: A case study of Shenzhen
TL;DR: Wang et al. as mentioned in this paper developed a novel method to visualise and evaluate the effect of license plate restriction policy by bridging diesel truck's license plate recognition data to emission inventories, which revealed that the impact of the peak restriction on air quality was limited if it only affected nonlocal diesel vehicles.
Journal ArticleDOI
The impacts from cold start and road grade on real-world emissions and fuel consumption of gasoline, diesel and hybrid-electric light-duty passenger vehicles.
TL;DR: In this paper , on-road measurements of 10 gasoline, four diesel and six full hybrid LDPVs were performed using portable emissions measurement systems (PEMS) in Macao, China.

TL;DR: In this paper, the authors provided an assessment of black-carbon climate forcing that is comprehensive in its inclusion of all known and relevant processes and that is quantitative in providing best estimates and uncertainties of the main forcing terms: direct solar absorption; influence on liquid, mixed phase, and ice clouds; and deposition on snow and ice.

TL;DR: The results suggest that, in addition to mitigating primary particulate emissions, reducing the emissions of secondary aerosol precursors from fossil fuel combustion and biomass burning is likely to be important for controlling China’s PM2.5 levels and for reducing the environmental, economic and health impacts resulting from particulate pollution.
Journal ArticleDOI
Strong radiative heating due to the mixing state of black carbon in atmospheric aerosols
TL;DR: Simulation of the evolution of the chemical composition of aerosols finds that the mixing state and direct forcing of the black-carbon component approach those of an internal mixture, largely due to coagulation and growth of aerosol particles.
Journal ArticleDOI
Air pollution in mega cities in China
TL;DR: In this paper, the authors present the current state of understanding of the air pollution problems in China's mega cities and identify the immediate challenges to understanding and controlling air pollution in these densely populated areas.
Journal ArticleDOI
Characteristics of PM 2.5 speciation in representative megacities and across China
TL;DR: Based on PM2.5 chemical data sets from literature and from surface observations, chemical species and reconstructed speciation of PM2.5 in representative Chinese megacities and across China were compared to draw insights into the characteristics of PM 2.5 speciation as mentioned in this paper.
