Phosphorus is an essential macronutrient that plays a crucial role in the regulation of biological productivity and biogeochemical cycling other biogenic elements. As large tidal wetland dominated by reeds Liaoning province, China, Shuangtai estuary unique ecosystem class. To better understand spatial temporal distributions total phosphorus (TP) sediments during period reed growth, eight sampli...
Chun-Tian Cheng*, K.W.Chau Department of Civil Engineering, Dalian University of Technology, Dalian, 116024, P.R. China Department of Civil and Structural Engineering, Hong Kong Polytechnic University, Hung Hom, Kowloon, Hong Kong Abstract: Flooding disaster is one of the most damaging natural disasters in China, with annual average losses costing more than 200 billion yuan in recent years. Aft...
The present paper divides the generally recognized Xianbei tombs into five groups. The first group is in the Hailar River valley; the second group, in the West Liaohe River valley; the third group, in the Chaoyang area; the fourth group, along the boundary between Inner Mongolia and Shanxi; and the fifth group, in northern Shanxi, middle Inner Mongolia and the zone a little west of them. In cul...
Inclusion of Perfluorooctane Sulfonate (PFOS) in the Stockholm Convention because of its exemptions, has resulted in increased annual production of PFOS-containing chemicals in China to accommodate domestic and overseas demands. Accordingly, concern about environmental contamination with perfluorinated compounds (PFCs), such as PFOS, has arisen. However, little information is available on the s...
Seven crude oils of known source and maturity, representing a natural sequence of increasing degree of biodegradation, were collected from reservoirs in the Liaohe Basin, NE China, in an effort to determine the magnitude and direction of isotopic shift of carbon and hydrogen in individual n-alkanes during microbial degradation. The results show that biodegradation has little effect on the carbo...
Hardly any previous studies have focused on the granitic dykes which intrude into Paleoproterozoic Liaohe Group in Liaodong Peninsula, northeast of North China Craton. In situ zircon U-Pb dating, Lu-Hf isotopic and geochemical analyses three representative monzogranite were taken this study. These relatively high content SiO2 (72.20%–74.78%) K2O (2.83%–6.37%), characteristics high-K calc-alkali...
