The efficient removal of phosphorous from water is an important but challenging task. In this study, we validated the applicability of a new commercially available nanocomposite adsorbent, i.e., a polymer-based hydrated ferric oxide nanocomposite （HFO-201）, for the further removal of phosphorous from the bioefftuent discharged from a municipal wastewater treatment plant, and the operating parameters such as the flow rate, temperature and composition of the regenerants were optimized. Labora- tory-scale results indicate that phosphorous in real bioeffluent can be effectively removed from 0.92 mg· L^-1 to 〈 0.5 mg· L^-1 （or even 〈 0.1 mg·L^-1 as desired） by the new adsorbent at a flow rate of 50 bed volume （BV） per hour and treatable volume of 3500-4000BV per run. Phosphorous removal is independent of the ambient temperature in the range of 15℃-40℃. Moreover, the exhausted HFO-201 can be regenerated by a 2% NaOH ＋ 5% NaC1 binary solution for repeated use without significant capacity loss. A scaled-up study further indicated that even though the initial total phosphorus （TP） was as high as 2 mg·L^-1, it could be reduced to 〈 0.5 mg·L^-1, with a working capacity of 4.4-4.8 g·L^-1 HFO- 201. In general, HFO-201 adsorption is a choice method for the efficient removal of phosphate from biotreated waste effluent.

Branched glycerol dialkyl glycerol tetraethers (GDGTs) were analyzed in peat samples taken from the Zoigê grassland, located on the eastern margin of the Qinghai-Tibetan Plateau. The mean annual air temperature (MAAT) and pH in the 210 Pb-dating peat core were reconstructed based on the cyclization of branched tetraethers (CBT) and methylation of branched tetraethers (MBT) indices for the last 150 years. The results showed that the MAAT and pH values involved three stages of variation over the last 150 years. The pH was stable and the MAAT decreased slowly by about 1°C from 1851 to 1927. The pH decreased rapidly by 0.6 and the MAAT decreased significantly by 2.5°C between 1927 and 1979. The pH and MAAT increased by 0.8 and 5°C, respectively, since the 1980s. The reconstructed temperatures correspond well to the mean winter temperatures reconstructed using tree-rings from the Jiuzhaigou Valley, situated at the boundary between the Qinghai-Tibetan Plateau and the Sichuan Basin. The estimated MAAT was similar to the temperatures reconstructed using tree-rings, indicating an increasing trend, as shown by local instrumental records from 1957 to 2001. These results provide further confidence in the application of proxies based on glycerol dialkyl glycerol tetraethers in peat records for continental paleoclimate reconstruction.

High-precision 210Pb dating technology was applied to a peat core with a time span of about 150 years that was taken from Hongyuan, Sichuan Province, China. The concentrations of total mercury (Hg) and stable isotope compositions of mercury in the peat core were measured using a LUMEX 915 instrument and multi-collector inductively coupled plasma mass spectrometer, respectively. Total mercury (Hg) concentrations in the peat core had a clearly increasing trend from the bottom to top of the core while δ 202Hg values (relative to NIST 3133) of peat had a decreasing trend. The total mercury (Hg) concentration varied from 16.7 to 101.3 ng/g and the δ 202Hg values ranged from –0.44‰± 0.14‰ to –1.45‰± 0.22‰. We clearly show that the study area experienced mercury pollution after the industrial revolution, and the mercury emitted from natural sources and anthropogenic sources had different Hg isotope signatures.

人类嗓音作为听觉环境的重要组成部分,包含了大量副语言信息以帮助识别个体身份,尤其对于盲人而言,视觉面孔经验的缺乏使得嗓音信息成为其感知对方个体特征的主要来源。通过结合正常视力者和盲人在嗓音选择性加工和嗓音身份加工方面的研究,尝试揭示普遍的人类嗓音加工模式以及盲人特异的嗓音加工机制。此外,与视觉面孔加工相关的梭状回脑区也参与并卷入了两类人群的嗓音加工任务,以此为基础梳理的视听整合模型和基于去掩蔽效应的跨模态重组假说,为这两类人群嗓音加工神经基础的差异性提供了相应的解释机制,未来研究希望可以进一步探究盲人的嗓音加工策略,以及考察左侧颞上沟/回脑区在嗓音加工中的作用。

Dear Editor,A few studies have focused on exploring APOE gene- related effects on cognitive functions and brain activities in healthy populations. Bondi et aL found that ε4 carriers perform significantly worse on the California Verbal Learning Test than non-carriers in non-demented old subjects （mean age, 72 years）ε11. But the results are not entirely consistent. For example, Scarmeas et aL found no effect of the E4 allele on neuropsychological performance[2] in young adults, and Jochemsen et al. found that the ε4 allele is associated with age-related cognitive decline[3]. Furthermore, protective and negative effects of the E2 allele on cognition are inconsistent[4＇ s]. APOE E2 is thought to be a protective allele for AD in the elderly population due to its role in the superior cognitive performance of ε2 carriers compared to E3 or E4 carriers[5]. However, the ε2 allele has also been found to have a negative effect on AD pathology[4].

通过^(210)Pb定年建立相应时间标尺,获得了若尔盖红原县泥炭柱中多环芳烃(PAHs)的含量和垂直分布特征。结果表明,泥炭中总PAHs的浓度为36.2～408ng/g dw,PAHs与泥炭TOC的含量具有较好的相关性。自20世纪初开始,PAHs浓度呈明显上升趋势,在1960年代初期达到峰值,其后开始下降。PAHs组成上主要以3～4环化合物为主,其中菲占总PAHs的45%,其次是荧蒽(16%)和芘(10%),体现出大气沉降来源的PAHs组成特征。PAHs成因判识指标表明,该地区泥炭中PAHs主要源自燃煤和汽车尾气排放;结合气流轨迹分析,我们认为四川盆地可能是其主要源区。泥炭中PAHs的浓度变化与泥炭TOC的含量、温度和降雨量有关。
