| Zusammenfassung |
| The purpose of this study is to develop an emission
inventory for major anthropogenic air pollutants and VOC species in the
Yangtze River Delta (YRD) region for the year 2007. A "bottom-up"
methodology was adopted to compile the inventory based on major emission
sources in the sixteen cities of this region. Results show that the
emissions of SO2, NOx, CO, PM10, PM2.5, VOCs,
and NH3 in the YRD region for the year 2007 are 2392 kt, 2293 kt, 6697 kt,
3116 kt, 1511 kt, 2767 kt, and 459 kt, respectively. Ethylene, mp-xylene,
o-xylene, toluene, 1,2,4-trimethylbenzene, 2,4-dimethylpentane, ethyl
benzene, propylene, 1-pentene, and isoprene are the key species contributing
77 % to the total ozone formation potential (OFP). The spatial
distribution of the emissions shows the emissions and OFPs are mainly
concentrated in the urban and industrial areas along the Yangtze River and
around Hangzhou Bay. The industrial sources, including power plants other
fuel combustion facilities, and non-combustion processes contribute about
97 %, 86 %, 89 %, 91 %, and 69 % of the total SO2, NOx,
PM10, PM2.5, and VOC emissions. Vehicles take up 12.3 % and
12.4 % of the NOx and VOC emissions, respectively. Regarding OFPs,
the chemical industry, domestic use of paint & printing, and gasoline
vehicles contribute 38 %, 24 %, and 12 % to the ozone formation in the
YRD region. |
