Sulfur hexafluoride (SF6) is the most potent greenhouse gas regulated under Kyoto Protocol, with a high global warming potential. In this study, SF6 emissions from China were inventoried for 1990-2010 and projected to 2020. Results reveal that highest emission contribution originates electrical equipment sector (about 70%), followed by magnesium production sector, semiconductor manufacture (each about 10%). Both agreements discrepancies found in comparisons of our estimates previously...
1,1,1,2-Tetrafluoroethane (HFC-134a), a potent greenhouse gas, breaks down to form trifluoroacetic acid (TFA). Lack of its gridded emissions inventories makes it difficult analyze the spatial distribution emissions. This study developed framework for national and HFC-134a bank emission calculations, validation environmental impact assessments. Within this framework, we used production consumption data along with factors compile inventory China. The results reveal an increase in emissions,...
Estimating the emissions of hydrochlorofluorocarbons (HCFCs) and hydrofluorocarbons (HFCs) is great significance for assessing global ozone depletion climate change, where from fluorochemical plants play an important role. However, no research has been conducted on HCFC HFC based observation data diffusion model. This study observed concentration two HCFCs six HFCs around three typical in China. It used Gaussian plume model to explore their emissions. The results showed that difference...
Nam Co Lake, located in the Tibet Plateau region, is highest and second-largest enclosed salt water lake China, a representative area for study of long-range atmospheric transport (LRAT) climate change perfluoroalkyl polyfluoroalkyl substances (PFASs). We analyzed causes spatial heterogeneity 18 PFASs 17 samples, 7 glacial runoff 8 non-glacial samples 9 sediment or around Lake 2023. The results showed that distribution various environmental media can be influenced by melting, salinity, pH,...
Tropospheric ozone (O3) is a typical secondary pollutant and produced by series of chemical reactions precursors such as nitrogen oxides (NOx) volatile organic compounds (VOCs) under light conditions. The emission in industrial cities large complex, the relationship between O3 its not clear, making it challenged to identify key factors source influencing formation. This study used observation-based-model (OBM), based on precursors’ observation data mechanism, analyze sensitivities...
Cohort evidence linking ozone (O3) exposure with mortality was sparsely investigated among the elderly in low- and middle-income countries. This study aims to quantify risk burden attributed chronic O3 Chinese older adults. A total of 30,874 adults aged ≥ 65 years were recruited from 3 national dynamic cohorts across 29 provincial regions China, 2005-2018. Annual warm-season (April-September) year-round PM2.5 concentrations estimated through well-validated satellite-based spatiotemporal...
Trifluoroacetic acid (TFA) has been attracting increasing attention worldwide because of its increased environmental concentrations and high aquatic toxicity. Atmospheric deposition is the major source TFA, but only a few studies have reported either air or fluxes for TFA. This first study to report atmospheric TFA in China, where an annular denuder filter pack collection system were deployed at highly urbanized site Beijing. In total, 144 samples collected over course 1 year (from May 2012...
As the usage of long-chain perfluoroalkyl and polyfluoroalkyl substances (PFASs) may be gradually restricted, short-chain even ultra-short-chain PFASs have been widely produced used, which has put forward new requirements for simultaneous analysis above substances. Using solid phase extraction two-fraction elution ultra-performance liquid chromatography tandem mass spectrometry (UPLC–MS/MS), an experimental method was established ultrashort-chain, short-chain, precursor...
In recent years, due to the production and use of per- poly-fluoroalkyl substances (PFASs), research on pollution characteristics sources PFASs in surface water precipitation China has attracted increasing attention. this study, related published articles with sampling years from 2010 2020 were reviewed, concentration levels, composition possible (rivers lakes) summarized, including those Tibetan Plateau region. The results show that concentrations different areas vary greatly, ranging 0.775...
