车载巡测在区域射频电磁环境质量监测与表征中的应用分析

对北京中央电视塔周围25 km²区域电磁环境质量分别进行了射频的网格法手工监测和车载巡测自动监测，通过SPSS软件等对两种监测方法获取的数据进行了统计对比分析，发现两组数据在总体水平及数值分布特征上较为接近，因此车载巡测监测可以替代网格法监测。以车载巡测数据为基础，绘制了实测数据的道路电磁地图，利用插值法绘制了区域电磁地图，对区域电磁环境质量进行了直观表征。从回应公众关注和城市电磁规划出发，建议今后可利用车载巡测监测加强时域和频域的监测。     

合成洗涤剂对小鼠诱变性研究

连续５天腹腔注射同一剂量（１／５ＬＤ５０）的合成洗涤剂，取小鼠骨髓细胞测定嗜多染色红细胞的微核率，研究表明，３种合成洗涤剂（加大香洗衣粉，洁牌餐具洗涤剂，恩威高级餐具洗洁精）使小鼠微核率有所增高，但恩威，洁牌餐具洗涤剂与对照无显著性差异。     

潜水含水层水位观测孔水位伪变化的观测与分析

结合CIRP试验场包气带的介质结构及渗透性特征，在S9孔进行了短期的孔中水位、孔口气压和温度测量，测量结果表明，观测孔水位波动与大气压变化有关，水位波动具有伪变化。水位伪变化对于试验场潜水位的监测有一定影响，因此，应对带有伪变化的水位观测结果进行必要的修正，以反映潜水位的真实动态。     

Temperature and Concentration Effects in Biomonitoring of Organic Air Pollutants

Up to now only very few studies in biomonitoring of organic air pollutants have been published taking into account the strong influence mean temperatures have on the accumulation process into plants during the course of the exposition. Temperature governed sorption as well as the plants vitality pose a major source of uncertainty making inter-study comparisons difficult. Different surface-to-volume ratios of plant foliage lead to strongly varying concentration effects in different plant species. Moreover a plants content of waxes and lipids must be considered in order to relate xenobiotic concentrations to the compounds being most efficient in the bioaccumulation process. Some of these factors are evaluated in regard to the use of plants as biomonitors for organic air pollutants. Another aim is to deduce the mean ambient gas phase concentrations from PAH concentrations determined in the biomonitor plants using vegetation-air partitioning coefficients which have been corrected for temperature dependent sorption as well as the plants lipid content. Restrictions of such approaches and methods of biomonitoring in general are discussed.     

Obligations to animals are based on rights

Some feminist philosophers criticize the idea of human rights because, they allege, it encapsulates male bias; it is therefore misguided, in their view, to extend moral rights to non-human animals. I argue that the feminist criticism is misguided. Ideas are not biased in favour of men simply because they originate with men, nor are ideas themselves biased in favour of men because men have used them prejudicially. As for the position that women should abandon theories of rights and embrace an ethic that emphasizes care: women who made this choice would not so much liberate themselves from the patriarchy as they would conform to its representation of women as emotional, subjective and irrational. There is, then, no good reason to withhold ascribing rights to non-human animals, based on the criticisms of rights made by some feminists.Some of the material in the discussion of the feminist critique of rights originally appeared in my The Case for Animal Rights: A Decade's Passing inA Quarter Century of Value Inquiry: Presidential Addresses of the American Society of Value Inquiry, edited by Richard T. Hull, pp. 451–455. Amsterdam and Atlanta, GA: Rodopi, 1994.

东南大陆岩石圈板块地体构造

东南大陆的地质构造模型,具有欧亚大陆边缘向洋增生的独特形式。除外来地体之外,或以扩张、地幔上涌,洋壳向大陆地壳转化,并不断向洋增生;或是大陆分裂,地幔柱——热点物质不断注入变薄和破裂了的地壳,形成区域性新的生长构造层,构造岩浆地质体表现为有独特属性的“A型”花岗岩和流纹岩链。这些高DI值的富硅富碱富钠质岩石,出现在欧亚大陆边缘的重力梯度带上。裂解带的地壳结构模式是上地壳存在着重力不稳定的硅铝低速带;中地壳有洋——陆过渡型地壳的“类裂谷型”结构,P波速度为6.3～6.4km/s的中间壳层;在下地壳下部有速度为7.0～7.4km/s的壳——幔混合型高速层;随着“异常”的上地幔的形成,有大范围的热活动和壳——幔边界穹窿,穹窿的地盖比正常区为为薄。由于化学库和化学边界层的横向不连续,可划分出古老基底和后期地质发展史完全迥异的两个亚板块;和以壳层(或幔层)断裂为边界特点的八个地体;一个以分裂为主,并具热点径迹的最新生长构造层的扩张——裂解构造岩浆地体。     

Fractionation of Cu, Pb and Zn in certified reference soils SRM 2710 and SRM 2711 using the optimized BCR sequential extraction procedure

Sequential extraction of metals from solid media is a common analytical tool used in environmental and exploration geochemistry. A number of procedures exist, but without harmonization and standardization, meaningful comparisons are tenuous without baseline data. A newly developed, standardized sequential extraction procedure (optimized BCR) was applied to two contaminated certified reference soils from Montana, US (SRM 2710 and SRM 2711) for Cu, Pb and Zn. Four operationally defined fractions were isolated, acid extractable, reducible, oxidizable, and residual (by aqua regia). Fraction-specific concentrations, percentages and recoveries for Cu, Pb and Zn were used to explore differences between the optimized BCR procedure and three other sequential extraction schemes with published data for SRM 2710 and 2711 (i.e. Tessier scheme, Geological Survey of Canada scheme and the original BCR scheme). Results indicate significant differences between the four schemes, even for schemes that are closely associated (i.e. the original and optimized BCR schemes). Order-of-magnitude fraction-specific concentration differences were observed, especially for Pb in the reducible fraction. Differences between schemes are worrisome because trends varied between metals, between fractions and between reference soils. These data reinforce the need for increased adoption of standardized sequential extraction procedures and further examination of different solid media.
