A new ion chromatography coupled with tandem mass spectrometry （IC-ESI-MS/MS） method, with automated sampling and on-line preconcentration, has been developed for the determination of perchlorate in Antarctic snow and ice at low part-per-trillion （ng]L） levels. To the best of our lmowledge, this is the first time that an analytical method is used for the determination of perchlorate in Antarctic snow and ice. The IC-ESI-MS/MS instrumentation consisted of an ICS2000 ion chromatography （IC） system coupled to an API3200 electrospray tandem mass spectrometer （ESI-MS/MS）. On-line preconcentration was realized through a six-port injector valve, a TAC-ULP1 concentrator column and an AS auto-sampler. Multiple reaction monitoring （MRM） mode was used to quantify the perch/orate anion. The transition of 35Cl]604- （m/z 98.9） into 3SC11603 （m[z 82.9） was monitored for quantifying the main analyte, and the transition of 37C11604 （m/z 100.9） into 37C1~603- （m]z 84.9） was monitored for examining a proper isotopic abundance ratio of 3sCl to 37C1, which was used as a confirmation tool. The limit of detection （LOD） and limit of quantitation （LOQ） for the method was 0.2 ng/ L and 0.5 ng/L, respectively. And this new method exhibited acceptable accuracy and precision for samples at ng/L levels. All the tested snow and ice samples were found to contain measurable amount of oerchlorate, ran^in~ from 10 nell to 340 nell..

Nitrogen is a vital element for life on Earth. Its cycling between the surface(atmosphere + crust) and the mantle has a profound influence on the atmosphere and climate. However, our understanding of the origin and evolution of Earth's nitrogen is still incomplete. This review presents an overview of the current understanding of Earth's nitrogen budget and the isotope composition of different reservoirs, laboratory constraints on deep nitrogen geochemistry, and our understanding of the origin of Earth's nitrogen and the deep nitrogen cycle through plate subduction and volcanism. The Earth may have acquired its nitrogen heterogeneously during the main accretion phase, initially from reduced, enstatite-chondrite-like impactors,and subsequently from increasingly oxidized impactors and minimal CI-chondrite-like materials. like Earth's surface, the mantle and core are also significant nitrogen reservoirs. The nitrogen abundance and isotope composition of these three reservoirs may have been fundamentally established during the main accretion phase and have been insignificantly modified afterwards by the deep nitrogen cycle, although there is a net nitrogen ingassing into Earth's mantle in modern subduction zones. However, it is estimated that the early atmosphere of Earth may have contained ～1.4 times the present-day atmospheric nitrogen(PAN),with ～0.4 PAN being sequestered into the crust via biotic nitrogen fixation. In order to gain a better understanding of the origin and evolution of Earth's nitrogen, directions for future research are suggested.

Following along with South Korean Pop culture sweeping across Chinese Mainland, Chinese market of South Korea tour is developing rapidly. An analysis demonstrates that the movie and television industry of South Korea is one of the most essential factors to attract the potential tourist from China. South Korean Pop culture is directly affecting rather the image of South Korean as a tourist destination than tourists＇ purchasing. And the paper suggests a set of ＂4S＂ strategy for South Korean to combine the elements of South Korean movies with those of tourism, so as to create an industrial development pattern characterized as ＂movies ＋ tourism＂.
