| 1 | Complex sources of air-soil-water pollution processes in the Miyun reservoir region显示文摘The comprehensive impact of atmospheric dry deposition and wet deposition and the pollution sources of farmlands, mining areas, and towns along the Baihe River on the water quality of Miyun reservoir is investigated from the angle of the complex sources of air-soil-water pollution processes, in the context of the 1990-2001 precipitation chemical data at Shangdianzi station--a WMO regional background air pollution monitoring station 15 km far from the Miyun reservoir, in conjunction with the atmospheric dry deposition and wet deposition data of the 2002-2003 Beijing City Air Pollution Observation Field Experiment (BECAPEX). Analysis results suggest that the major ions in precipitation in the Miyun reservoir region in this period were SO, NO, NH and Ca2+; wet acid deposition quantity of Miyun reservoir in the summer half year (April to September) was greater than the quantity in the winter half year (October to March), and the annual wet acid deposition in the reservoir exhibited a rising trend with the mean 1038.45 t, the maximum 1766.31 t occurred in 1996, and the minimum 604.02 t in 1994; the long-term averaged pH of atmospheric precipitation in the Miyun reservoir region was 5.20, i.e. weakly acidic, and the interannual variation of pH values displayed a falling trend. pH values of water body at various depths in the Miyun reservoir were all greater than 7.0, but they exhibited vertical and horizontal nonhomogeneity, and at the same region pH decreased vertically with depth; the 2002 and 2003 annual dustfalls in the Miyun reservoir were 13513.08 t and 3577.64 t, respectively, and the spring dustfall was the number one in a year, accounting for the 61.91% and 44.56% of the annual totals of 2002 and 2003, respectively. Because the atmospheric dry deposition and wet depositions contain multiple types heavy metal elements and harmful elements, they to some extent exacerbated the eutrophication, acidification and potential heavy metal pollution of the reservoir water. The above comprehensive analysis results reveal the complex source characters of the air-soil-water pollution process and the multi-sphere interaction effect. Besides, summer (rainy season) is a season when local soil pollutants enter the water system of reservoir after being washed out by torrential rain or heavy precipitation, which starts the air-soil- water chaining pollution processes, and results in the water pollution of rivers and reservoirs. It is found from the statistical analysis in this paper that the water pollution of Miyun reservoir was correlated with the rain wash-out and confluent flow in the peripheral and upstream local region of the reservoir, and the pollutant concentration of the reservoir water was significantly correlated with the upstream local region precipitation. Those correlation characters reveal the effect of the air-soil-water multi-spheric interaction of reservoir water pollution process. This paper presents the point of view of the complex source analysis of reservoir water pollution and a technical approach for tracing the spatial distribution of the upstream pollution source of the water systems of reservoir. | YANG Dongzhen, XU Xiangde, LIU Xiaoduan, XU Qing, DING Guoan, CHENG Xinghong, CHEN Huailiang, ZHOU Huaigang, WANG Zhenfa, WANG Wenyan Key Laboratory of Atmospheric Chemistry, Center for Atmosphere Watch and Services, Chinese Academy of Meteorological Sciences, CMA, Beijing 100081, China Key Laboratory of Meteorological Disasters, CAMS, Beijing 100081, China National Center for Geological Testing, Beijing 100037, China Meteorological Bureau of Henan Province, Zhenzhou 450000, China Shangdianzi Background Atmospheric Pollution Observation Station, Miyun County, Beijing 101507, China | 2005 | Science China Earth Sciences2005，48，z2： | 4 |

| 8 | 全球养鸡业的集约化发展对禽流感之繁衍和流行的影响显示文摘在人类驯化野生禽类的4500年间,禽流感一直在人类间流传,而且历来是人类面临的传染性最为严重的疾病。只是1997年以来,随着H5N1亚型高致病性禽流感(HPAI)在人类中传播的危险得到普遍的承认,死亡率高于60%的禽流感也就成了人类健康最为潜在的威胁。H5N1目前还局限于鸟类间。如果病毒能够获得在人类中传播并保留其毒性的能力,H5N1(60%的死亡率)理论上可以引发人类史上危害最大的传染病。如果这种传染病暴发, | Miyun Park | 2008 | 中国家禽2008，30，23： | 0 |
| 9 | Chemical constituents and coagulation effects of the flowers of Rosa chinensis Jacq.显示文摘In this paper,the flowers of Rosa chinensis Jacq.were investigated and 14 compounds were isolated and identified,namely kaempferol(1),quercetin(2),isoquercitrin(3),afzelin(4),quercitrin(5),phenylethyl glucopyranoside(6),avicularin(7),juglanin(8),nicotiflorin(9),phenylethyl-6′-O-galloyl-β-D-glucopyranoside(10),tiliroside(11),methyl gallate(12),8-O-methylherbacetin-3-O-β-D-sophoroside(13),gallic acid(14).Among these compounds,compounds 7,9,12 and 13 were isolated from R.chinensis for the first time.These compounds and extracts of R.chinensis.were studied for coagulation activity in vitro.The results showed that tiliroside(11)had good effect on promoting blood coagulation,and the effect of tiliroside was better than that of Yunnanbaiyao.Juglanin(8)and nicotiflorin(9)could significantly shorten thrombin time(TT)and significantly elevated fibrinogen(FIB),which proved that juglanin and nicotiflorin had good procoagulant effect. | Peiqing Wang Miyun Hu Li Wang Jiaojiao Qu Yuhang Liu Changqin Li Zhenhua Liu Changyang Ma Wenyi Kang | 2023 | Journal of Future Foods2023，3，2： | 0 |
