Journal ArticleDOI
Occurrence, gas/particle partitioning and carcinogenic risk of polycyclic aromatic hydrocarbons and their oxygen and nitrogen containing derivatives in Xi'an, central China
Chong Wei,Yongming Han,Benjamin A. Musa Bandowe,Junji Cao,Ru-Jin Huang,Haiyan Ni,Jie Tian,Wolfgang Wilcke +7 more
TL;DR: Gaseous compounds contributed 29 to 44% of the total health risk in March and September, respectively and both absorption into organic matter in particles and adsorption onto the surface of particles were important for PAHs and OPAHs in both sampling periods.
Journal ArticleDOI
Brown Carbon Aerosol in Urban Xi'an, Northwest China: The Composition and Light Absorption Properties.
Ru-Jin Huang,Lu Yang,Junji Cao,Yang Chen,Qi Chen,Yong Jie Li,Jing Duan,Chongshu Zhu,Wenting Dai,Kai Wang,Kai Wang,Chunshui Lin,Chunshui Lin,Haiyan Ni,Haiyan Ni,Joel C. Corbin,Yunfei Wu,Renjian Zhang,Xuexi Tie,Thorsten Hoffmann,Colin D. O'Dowd,Uli Dusek +21 more
TL;DR: The light absorption coefficient of methanol-soluble BrC at 365 nm was found to correlate strongly with both parent polycyclic aromatic hydrocarbons and their carbonyl oxygenated derivatives in all seasons, and fractional solar absorption by BrC relative to element carbon in the ultraviolet range is significant during winter.
Journal ArticleDOI
Emission characteristics of carbonaceous particles and trace gases from open burning of crop residues in China
Haiyan Ni,Yongming Han,Junji Cao,Junji Cao,L.-W. Antony Chen,L.-W. Antony Chen,L.-W. Antony Chen,Jie Tian,Xiaoliang Wang,Xiaoliang Wang,Judith C. Chow,John G. Watson,Qiyuan Wang,Ping Wang,Hua Li,Ru-Jin Huang,Ru-Jin Huang +16 more
TL;DR: In this paper, a custom-made combustion chamber was used to determine pollutants (i.e. CO2, CO, PM2.5, organic carbon (OC) and elemental carbon (EC)) of wheat straw, rice straw and corn stalk; the three major agricultural crop residues in China.
Journal ArticleDOI
A Biomass Combustion Chamber: Design, Evaluation, and a Case Study of Wheat Straw Combustion Emission Tests
Jie Tian,Junji Cao,Junji Cao,Yongming Han,Haiyan Ni,L.-W. Antony Chen,L.-W. Antony Chen,Xiaoliang Wang,Xiaoliang Wang,Ru-Jin Huang,Hans Moosmueller,John G. Watson,John G. Watson +12 more
TL;DR: In this paper, a combustion chamber for open biomass burning is presented, with a focus on crop residue combustion in Northwest China, and a series of evaluation tests are conducted, demonstrating its applicability in emission studies and demonstrating reproducibility and comparability of the derived emission factors with prior studies.
Journal ArticleDOI
Water-Insoluble Organics Dominate Brown Carbon in Wintertime Urban Aerosol of China: Chemical Characteristics and Optical Properties
Ru-Jin Huang,Ru-Jin Huang,Lu Yang,Jincan Shen,Wei Yuan,Yuquan Gong,Jie Guo,Wenjuan Cao,Jing Duan,Haiyan Ni,Haiyan Ni,Chongshu Zhu,Wenting Dai,Yong Jie Li,Yang Chen,Qi Chen,Yunfei Wu,Renjian Zhang,Ulrike Dusek,Colin D. O'Dowd,Thorsten Hoffmann +20 more
TL;DR: These three BrC fractions show large differences in light absorption and chromophore composition, but the chromophores responsible for light absorption are similar in Xi'an and Beijing in winter 2013-2014.
