Global atmospheric emissions of 16 polycyclic aromatic hydrocarbons (PAHs) from 69 major sources were estimated for a period 1960 to 2030. Regression models and technology split method used estimate country time specific emission factors, resulting in new PAH factor variation among different countries over time. 2007 spatially resolved 0.1° × grids based on newly developed global high-resolution fuel combustion inventory (PKU-FUEL-2007). The total annual PAHs was 504 Gg (331–818 Gg, as...
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...
Emission quantification of primary particulate matter (PM) is essential for assessment its related climate and health impacts. To reduce uncertainty associated with global emissions PM2.5, PM10, TSP, we compiled data high spatial (0.1° × 0.1°) sectorial (77 sources) resolutions 2007 based on a newly released fuel product (PKU-FUEL-2007) an emission factor database. Our estimates developing countries are higher than those previously reported. Spatial bias large could be reduced by using...
Indoor combustion of crop residues for cooking or heating is one the most important emission sources polycyclic aromatic hydrocarbons (PAHs) in developing countries. However, data on PAH factors (EFs) burning indoor, particularly those measured field, were scarce, leading to large uncertainties inventories. In this study, EFs PAHs nine commonly used burned a typical Chinese rural stove simulated kitchen. The total averaged at 63 ± 37 mg/kg, ranging from 27 142 which higher than chamber...
Air pollutants from residential solid fuel combustion are attracting growing public concern. Field measured emission factors (EFs) of various air for fuels close to the reality and urgently needed better estimations. In this study, particulate matter (PM), organic carbon (OC), elemental (EC), polycyclic aromatic hydrocarbons (PAHs) combustions coal briquette, cake, wood were in rural Heshun County, China. The EFs PM, OC, EC 8.1-8.5, 2.2-3.6, 0.91-1.6 g/kg burnt a simple metal stove,...
Significance In this study, we have developed a unique global black carbon (BC) emission inventory using 10-km grid based on the latest source and factor information. The is used to model BC concentrations atmospheric aerosol climate model, with high-resolution for Asia, better resolve exposure of populations elevated concentration. even higher resolution (10 km) North China Plain. Finally, population are evaluated.
Both particulate matter (PM) and black carbon (BC) impact climate change human health. Uncertainties in emission inventories of PM BC are partially due to large variation measured factors (EFs) lack EFs from developing countries. Although there is a debate whether thermal-optically elemental (EC) may be referred as BC, EC often treated the same mass BC. In this study, (EFPM) (EFEC) for 9 crop residues 5 coals were actual rural cooking coal stoves using balance method. The dependence on fuel...
By use of biogenic silica as an inert marker, it is shown that chlorophyll a and its derivatives can be destroyed or absorbed during passage through the gut herbivorous copepod. This observation contradictory to hypothesis converted pheophorbide with 100% molar efficiency. The currently used equations for measuring pheopigment by fluorescence cannot give concentration pheopigment.
Residential wood combustion is one of the important sources air pollution in developing countries. Among pollutants emitted, parent polycyclic aromatic hydrocarbons (pPAHs) and their derivatives, including nitrated oxygenated PAHs (nPAHs oPAHs), are concern because mutagenic carcinogenic effects. In order to evaluate impacts on regional quality human health, emission inventories, based realistic factors (EFs), needed. this study, EFs 28 pPAHs (EFPAH28), 9 nPAHs (EFPAHn9), 4 oPAHs (EFPAHo4)...
Black carbon (BC) plays an important role in both climate change and health impact. Still, BC emissions as well the historical trends are associated with high uncertainties existing inventories. In present study, global from 1960 to 2007 were estimated for 64 sources, by using recompiled fuel consumption emission factor data sets. Annual had increased 5.3 (3.4-8.5 interquartile range) 9.1 (5.6-14.4) teragrams during this period. Our estimations 11-16% higher than those previous Over period,...
Emission characterization of polycyclic aromatic hydrocarbons (PAHs) from residential combustion crop residues, woody material, coal, and biomass pellets in domestic stoves rural China are compared term emission factors (EFs), influencing factors, composition profiles, isomer ratios phase distributions. The EFs PAHs vary by 2 orders magnitude among fuel types suggesting that a detailed categorization is useful the development an inventory potential abatement replacing dirty fuels with...
Indoor solid fuel combustion is a dominant source of polycyclic aromatic hydrocarbons (PAHs) and oxygenated PAHs (OPAHs) the latter are believed to be more toxic than former. However, there limited quantitative information on emissions OPAHs from combustion. In this study, emission factors (EFOPAH) for nine commonly used crop residues five coals burnt in typical residential stoves widely rural China were measured under simulated kitchen conditions. The total EFOPAH ranged 2.8 ± 0.2 8.1 2.2...
Published emission factors (EFs) often vary significantly, leading to high uncertainties in estimations. There are few reliable EFs from field measurements of residential wood combustion China. In this study, 17 fuels and one bamboo were combusted a typical stove rural China measure realistic particulate matter (PM), organic carbon (OC), elemental (EC), as well investigate the influence fuel properties conditions on EFs. Measured PM, OC, EC (EF(PM), EF(OC), EF(EC), respectively) range...
Abstract Resolving regional carbon budgets is critical for informing land-based mitigation policy. For nine regions covering nearly the whole globe, we collected inventory estimates of carbon-stock changes complemented by satellite biomass where data are missing. The net land–atmospheric exchange (NEE) was calculated taking sum change and lateral fluxes from crop wood trade, riverine-carbon export to ocean. Summing up NEE all regions, obtained a global ‘bottom-up’ land anthropogenic CO2...
Biomass pellets are emerging as a cleaner alternative to traditional biomass fuels. The potential benefits of using include improving energy utilization efficiency and reducing emissions air pollutants. To assess the environmental, climate, health significance replacing fuels with pellets, it is critical measure emission factors (EFs) various pollutants from pellet burning. However, only few field measurements have been conducted on carbon monoxide (CO), particulate matter (PM), polycyclic...
Abstract Phosphorus (P) availability in soils limits crop yields many regions of the World, while excess soil P triggers aquatic eutrophication other regions. Numerous processes drive global spatial distribution agricultural soils, but their relative roles remain unclear. Here, we combined several data sets describing these drivers with a dynamics model to simulate and assess contributions different at scale. We analysed both labile inorganic ( ILAB ), proxy pool involved plant nutrition...
Elevated atmospheric nitrogen (N) deposition has significantly influenced aquatic ecosystems, especially with regard to their N budgets and phytoplankton growth potentials. Compared a considerable number of studies on oligotrophic lakes oceanic waters, little evidence for the importance been generated eutrophic lakes, even though emphasis placed reducing external inputs control eutrophication in these lakes. Our high-resolution observations depositions riverine biologically reactive species...
