An Euler atmospheric transport model (Canadian Model for Environmental Transport of Organochlorine Pesticides, CanMETOP) was applied and validated to estimate polycyclic aromatic hydrocarbon (PAH) ambient air concentrations at ground level in China based on a high-resolution emission inventory. The results were used evaluate lung cancer risk the Chinese population caused by inhalation exposure PAHs. uncertainties model, exposure, analysis assessed using Monte Carlo simulation, taking into...
Black carbon (BC) emissions from China are of global concern. A new BC emission inventory (PKU-BC(China)) has been developed with the following improvements: (1) The factor database was updated; (2) a 0.1° × gridded map produced for 2007 based on county-level proxies; (3) time trends were derived 1949-2007 and predicted 2008-2050; (4) uncertainties associated quantified. It estimated that 1957 Gg emitted in 2007, which is greater than previously reported. Residential coal combustion largest...
Residential contributions are substantially magnified from energy use, emissions, air pollution, to health impacts.
In addition to many recent actions taken reduce emissions from energy production, industry, and transportation, a new campaign substituting residential solid fuels with electricity or natural gas has been launched in Beijing, Tianjin, 26 other municipalities northern China, aiming at solving severe ambient air pollution the region. Quantitative analysis shows that can accelerate transition significantly, if planned target be achieved, more than 60% of households are projected remove by 2021,...
Polychlorinated biphenyl (PCB) concentrations in surface soil samples (0-20 cm) from 52 sites (4 background, 39 rural, and 9 urban) across China 2005 are presented. The average concentration of total PCBs among all the was 515 pg/g dry weight (dw), approximately one-tenth that global background 1998. Differences less than 1 order magnitude were found between rural sites, indicating a generally uniform distribution Chinese background/rural soil. While major PCB homologue group is hexa-PCB...
Polychlorinated biphenyl (PCB) concentrations in air and soil, measured by various research groups from around the world, were compiled analyzed. Data for available most regions, particularly Europe Asia. The average (pg/m3) ΣPCB at background sites 70 (5.1−170) Europe, 79 (49−120) North America, 66 (18−110) South 270 (9−670) Central 59 (17−150) Asia, 15 (13−17) Australia. soils exhibited better global coverage compared to regions. soil (pg/g dry weight) 7500 (47−97 000) 4300 (110−25 1400...
Household energy use is an important aspect of environmental pollution and sustainable development. From a nationwide residential survey, this study revealed that household fuel "stacking"-mixed multiple fuels-is becoming noticeable over the 20 years from 1992 to 2012, particularly in northern China where space heating needed winter. Approximately 28% rural households used only one single type 1992, whereas percentage declined merely 11% 2012. The number types correlated positively with...
The presence of sulfur dioxide (SO2) in the air is a global concern because its severe environmental and public health impacts. Recent evidence from satellite observations shows rapid changes spatial distribution SO2 emissions, but such features are generally missing emission inventories that use bottom-up method due to lack up-to-date information, especially developing countries. Here, we rely on latest data available activities, control measures, factors estimate emissions for period...
Two decades of atmospheric measurements polycyclic aromatic hydrocarbons (PAHs) were conducted at three Arctic sites, i.e., Alert, Canada; Zeppelin, Svalbard; and Pallas, Finland. PAH concentrations decrease with increasing latitude in the order Pallas > Zeppelin Alert. Forest fire was identified as an important contributing source. Three representative PAHs, phenanthrene (PHE), pyrene (PYR), benzo[ a]pyrene (BaP) selected for assessment their long-term trends. Significant decline these PAHs...
Abstract. Lanzhou, which is located in a steep alpine valley western China, one of the most polluted cities China during wintertime. In this study, an Aerodyne high-resolution time-of-flight aerosol mass spectrometer (HR-ToF-AMS), seven-wavelength aethalometer, and scanning mobility particle sizer (SMPS) were deployed 10 January to 4 February 2014 study concentrations, chemical processes, sources submicrometer particulate matter (PM1). The average PM1 concentration was 57.3 µg m−3 (ranging...
The quantification of nitrogen oxide (NOx) emissions is critical for air quality modeling. Based on updated fuel consumption and emission factor databases, a global inventory was compiled with high spatial (0.1° × 0.1°), temporal (monthly), source (87 sources) resolutions the period 1960 to 2014. monthly data have been uploaded online (http://inventory.pku.edu.cn), along number other pollutant greenhouse gas free download. Differences in profiles, not total quantities, between our results...
Accurate estimation of black carbon (BC) emissions is essential for assessing the health and climate impact this pollutant. Past emission inventories were associated with high uncertainty due to data limitations, recent information has provided a unique updating opportunity. Moreover, understanding drivers that cause temporal changes research value. Here, we update global BC estimates using new on activities factors (EFs). The inventory covers 73 detailed sources at 0.1° × spatial resolution...
Abstract As China ramped-up coal power capacities rapidly while CO 2 emissions need to decline, these would turn into stranded assets. To deal with this risk, a promising option is retrofit co-fire biomass and eventually upgrade CCS operation (BECCS), but the feasibility debated respect negative impacts on broader sustainability issues. Here we present data-rich spatially explicit approach estimate marginal cost curve for decarbonizing sector in BECCS. We identify potential of 222 GW 2836...
Abstract China’s strategy to concurrently address climate change and air pollution mitigation is hindered by a lack of comprehensive information on source contributions health damage carbon emissions. Here we show notable discrepancies between CO 2 emissions fine particulate matter (PM 2.5 )-related mortality using adjoint emission sensitivity modeling attribute premature in 2017 53 sector fuel/process combinations with high spatial resolution. Our findings reveal that monetized PM exceeds...
Polychlorinated biphenyl (PCB) concentrations were measured in a concurrent air and surface soil sampling program across China. Passive samples collected for approximately 3 months from mid-July to mid-October, 2005 using polyurethane foam (PUF) disk type samplers at 97 sites subset of 51 the same year. As expected, (pg m−3) highest urban (mean 350 ± 218) followed by rural (230 180) background (77 50). The PCB homologue composition was similar China, with no distinction among site types,...
