Source Apportionment Using Radiocarbon and Organic Tracers for PM2.5 Carbonaceous Aerosols in Guangzhou, South China: Contrasting Local- and Regional-Scale Haze Events
Junwen Liu,Jun Li,Yan-Lin Zhang,Di Liu,Ping Ding,Chengde Shen,Kaijun Shen,Quanfu He,Xiang Ding,Xinming Wang,Duohong Chen,Soenke Szidat,Gan Zhang +12 more
TL;DR: Investigation of the atmospheric behavior of carbonaceous aerosols during hazy and normal days using radiocarbon ((14)C) and biomass burning/secondary organic aerosol (SOA) tracers during winter in Guangzhou, China found that haze episodes were formed either abruptly by local emissions or through the accumulation of particles transported from other areas.
Journal ArticleDOI
Occurrence of butyltin compounds in the waters of selected lakes, rivers and coastal environments from China
TL;DR: In this paper, the presence of butyltin compounds was investigated for the first time in selected lakes, rivers and coastal environments of China using headspace solid phase micro-extraction after hydride generation with sodium tetrahydroborate (NaBH4).
Journal ArticleDOI
Organochlorine pesticides in surface soils from obsolete pesticide dumping ground in Hyderabad City, Pakistan: Contamination levels and their potential for air-soil exchange
Ambreen Alamdar,Jabir Hussain Syed,Riffat Naseem Malik,Athanasios Katsoyiannis,Junwen Liu,Jun Li,Gan Zhang,Kevin C. Jones +7 more
TL;DR: The need of spatio-temporal monitoring of OCPs at local and regional scale to assess and remediate the future adverse implications of organochlorine pesticides is emphasized.
Journal ArticleDOI
Diurnal and nocturnal variations of PAHs in the Lhasa atmosphere, Tibetan Plateau: Implication for local sources and the impact of atmospheric degradation processing
TL;DR: In this paper, the USEPA priority polycyclic aromatic hydrocarbons (PAHs) and benzo[e]pyrene were detected in the air samples collected at two suburban sites in Lhasa city.
Journal ArticleDOI
Atmospheric deposition of polycyclic aromatic hydrocarbons (PAHs) to a coastal site of Hong Kong, South China
Fobang Liu,Fobang Liu,Yue Xu,Junwen Liu,Di Liu,Jun Li,Gan Zhang,Xiangdong Li,Shichun Zou,Senchao Lai +9 more
TL;DR: The contribution of atmospheric deposition to PAH concentrations in the sediments was estimated to be 30% to 40% in the coastal regions of South China as discussed by the authors, and the annual mean washout ratio, defined as the ratio between the particle-associated concentrations of PAHs in precipitations and aerosols, was 3.4 × 105 in this study.
