“…An attempt was made to relate the regional AQI to the observed TGM concentrations. The hourly AQI showed positive correlation with the hourly concentrations of SO 2 and PM 10 released from coal combustion in China [Streets and Waldhoff, 2000;Ye et al, 2003]. The hourly mean TGM concentrations were plotted against three AQI ranks in Figure 7.…”

To evaluate the impact of regional mercury (Hg) emissions and understand possible source regions of atmospheric Hg in Eastern China, 2 year observation for speciated atmospheric Hg was conducted at the Dameishan Atmospheric Observatory, a mountain site near the east coast of China. The observed concentration of total gaseous Hg (TGM) was 3.3 ± 1.4 ng m À3 . During the sampling period, gaseous oxidized Hg and particulate bound Hg were 6.7 ± 4.3 pg m À3 and 180 ± 110 pg m À3 in winter and 5.9 ± 3.4 pg m À3 and 130 ± 100 pg m À3 in spring, respectively. The relatively high mean concentration of TGM was mainly caused by regional anthropogenic emissions and occasional long-range transport from domestic source regions. Seasonal variation in the TGM concentration was observed with lower values in the wet monsoon season (from May to September) and higher values in the dry monsoon season (from October to April). Backward trajectories and potential source contribution function analysis suggested that anthropogenic Hg emission from coal combustion in the Yangtze River Delta region was the most likely cause for the elevated TGM concentrations. Relatively clean air originating from the East China Sea was the most possible cause for the observed low TGM concentrations. Positive correlation between TGM concentration and air quality index suggests that emissions that influenced regional air quality contributed to the elevated TGM concentrations.

We develop a source-specific high-resolution emission inventory for the Shandong region of eastern China for 2000 and 2020. Our emission estimates for year 2000 are higher than other studies for most pollutants, due to our inclusion of rural coal consumption, which is significant but often underestimated. Still, our inventory evaluation suggests that we likely underestimate actual emissions. We project that emissions will increase greatly from 2000 to 2020 if no additional emission controls are implemented. As a result, PM 2.5 concentrations will increase; however O 3 concentrations will decrease in most areas due to increased NO x emissions and VOC-limited O 3 chemistry. Taking Zaozhuang Municipality in this region as a case study, we examine possible changes in emissions in 2020 given projected growth in energy consumption with no additional controls utilized (BAU), with adoption of best available end-of-pipe controls (BACT), and with advanced, low-emission coal gasification technologies (ACGT) which are capable of gasifying the high-sulfur coal that is abundant in China. Emissions of NH 3 are projected to be 20% higher, NMVOC 50% higher, and all other species 130-250% higher in 2020 BAU than in 2000. Both alternative 2020 emission scenarios would reduce emissions relative to BAU. Adoption of ACGT, which meets only 24% of energy service demand in Zaozhuang in 2020 would reduce emissions more than BACT with 100% penetration. In addition, coal gasification technologies create an opportunity to reduce greenhouse gas emissions by capturing and sequestering CO 2 emissions below ground. r

“…Fortunately, the prevailing winds are generally easterly. The SO 2 emissions in Hong Kong are 5 times smaller than those of adjacent Guangdong County, in southern China: 0.15 Mt y −1 versus 0.72 Mt y −1 (Streets and Waldhoff, 2000). High sulphur-content fuel oils were banned in Hong Kong in 1990, and regulations were put in place for the sulphur content of automotive diesel not to exceed 0.2% by mass (April 1995) and 0.05% SO 4 † CW 10.7 (5.1) 47 9.8 (5.4) 47 11.6 (6.6) 59 8.8 (5.5) 61 9.5 (5.0) 59 SSP 9.7 (5.1) 46 9.4 (4.6) 51 9.7 (5.1) 55 8.8 (5.5) 59 9.0 (6.0) 60 YL 11.5 (5.1) 23 9.9 (6.1) 53 11.0 (6.6) 59 9.3 (6.1) 61 9.5 (5.6) 59 V CW 7.8 (5.4) 47 5.1 (2.6) 47 7.5 (7.2) 59 6.0 (5.1) 61 6.1 (4.8) 59 SSP 8.6 (6.9) 46 6.9 (5.6) 51 6.…”

Abstract. Five year (1995Five year ( -1999 datasets for inorganic major and trace components in PM 10 from three monitoring sites in Hong Kong are presented. The concentrations of most chemical constituents show a high degree of seasonality, with high concentrations in winter but low ones in summer, resulting from the combined effects of summer monsoon scavenging and the influx of the continental air mass of the winter monsoon. High correlations exist within crustal components, as well as within sea-salt components. Non-seasalt sulphate and ammonium ion contributions to the PM 10 mass are similar at all sites and are greatest in the winter months, showing the importance of non-local contributions. The concentrations of chemical components in PM 10 from this study are compared with those in wet deposition in Hong Kong, as well as with PM 10 results from other countries. In general, the Asian countries experience more elevated concentrations of PM 10 .
