Different phosphorus compositions (TP, IP and OP) were determined in surface sediments of the Yellow Sea (YS) and the East China Sea (ECS),sampled from two cruises between March and June, 2011. The results showed that, contents of TP were from 10.50 micromol x g(-1) to 24.10 micromol x g(-1), IP ranged from 7.14 micromol x g(-1) to 17.10 micromol x g(-1)(More)
OBJECTIVE This study examined the risk factors for decreased bone mineral density (BMD) in postmenopausal women with schizophrenia. METHODS Cluster sampling method was adopted in this large-sample, cross-sectional study. A total of 219 postmenopausal female inpatients with schizophrenia were selected and interviewed in Beijing. The average age of the(More)
A survey was carried out in the Yellow Sea and the East China Sea from March 17 to April 06 of 2011. Dissolved CH4 in various depths were measured and sea-to-air fluxes were estimated. Methane concentrations in surface and bottom waters ranged between 2.39-29.67 nmol x L(-1) and 2.63-30.63 nmol x L(-1), respectively. Methane concentrations in bottom waters(More)
The distributions and pollution status of heavy metals in the suspended particles were investigated in the Wanquan and Wenchang/Wenjiao estuaries and the coastal area of eastern Hainan in July 2008. The concentrations of metal elements (Al, Fe, Mn, Cr, Cu, Ni, V, Zn) were determined by ICP-AES after microwave digestion. Multivariate statistical methods (e.(More)
