南通市冬季PM2.5中水溶性离子污染特征

根据南通市2016和2017年冬季大气多参数站自动监测PM2.5数据和在线离子色谱分析仪Marga监测的PM2.5中水溶性离子数据,分析了南通市冬季PM2.5中水溶性离子污染特征。结果表明,南通市2016和2017年冬季,ρ(PM2.5)分别为58和54μg/m 3,均高出其年均值(14μg/m^3);ρ(水溶性离子)总占ρ(PM2.5)百分比分别为74.5%和74.3%;二次离子ρ(NO3^-、SO4^2-和NH4^+)占ρ(PM2.5)百分比分别为66.8%和66.6%;各水溶性离子占比大小依次为:NO3^-、SO4^2-、NH4^+、Cl^-、K^+、Na^+、Ca^2+、Mg^2+。对ρ(NO3^-)/ρ(SO 4^2-)分析表明,移动源已经成为南通市冬季的主要污染源,且呈逐年增强趋势。对氯氧化率和硫氧化率的分析表明,南通市冬季存在较明显的二次污染,SO2的转化程度大于NO2。除Na^+和Mg^2+外,其他离子与PM2.5均呈显著相关性,NO3^-、SO4^2-与NH4^+之间的相关系数最高,Cl^-与除Na^+外的所有阳离子均呈显著相关性。     

A Survey of Trace Metals in Vegetation, Soil and Lower Animal Along Some Selected Major Roads in Metropolitan City of Lagos

The concentration of trace metals (Cd, Cu, Pb and Zn) in a total of 144 samples of grass, soil and lower animal (earthworm, Lybrodrilus violaceous) were collected and analysed for their metallic content. Levels of cadmium ranged from 0.01–0.07 g g^–1; 0.01–0.12 g g^–1 and from trace–0.05 g g^–1 dry weight for plant, soil and animal samples respectively. Mean concentration of copper ranged 0.10–1.48 g g^–1; 0.10–2.90 g g^–1 and 0.01–0.08 g g^–1 for samples in similar order as above. The levels of Pb varied from 0.01–0.14 g g^–1; 0.02–0.23 g g^–1 and from trace–0.07 g g^–1 while that of Zn ranged from 0.19–1.80 g g^–1; 0.51–3.35 g g^–1and 0.01–0.08 g g^–1 also in the same order of samples as mentioned above. Levels of metals in soil samples were higher than the background levels with the exception of Zn but lower than European Union (EU) limits. The results generally revealed the presence of metals in plant and animal samples and metal dynamics up the food chain is highly possible. Acceptable recoveries of the spiking experiment validate the experimental protocol.

和田市土地利用结构变化研究

我国正处在城市化急速发展的时期。城市从数量、规模等各方面都在膨胀，这给城市土地利用带来了一系列问题。本文在综合分析和田市城市土地利用现状和未来发展要求的基础上，为解决人类在高强度经济活动中，特别是在农村经济建设和城乡建设快速发展的条件下。针对如何解决土地资源的合理利用、环境恶化及持续发展之间的矛盾。提出了和田市未来合理开发利用土地资源、产业结构的调整、城市功能区的布局和进行城市建设等方面可行性方案。     

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.

城市生活垃圾理化性质的动态特性分析

对太原市城市生活垃圾的组成、化学元素及重金属等进行了1年(每月2次)共24次的分析。结果表明,太原市生活垃圾的组成在焚烧过程中,能产生低位热值(Q低)的有机物占(44.28±2.24)％,不产生低位热值的无机物占(13.94±2.01)％,混合物(破碎的动植物碎片及粘附在其上面的灰、土、砂)占(43.36±8.67)％。垃圾中可燃物比例较高,水分含量较低,有利于焚烧和热解,低位热值(Q低)平均值为(5590.8±1252.3)kJ/kg,但低位热值随季节变化较大。垃圾中化学元素硫(S)、氯(Cl)、氮(N)、氢(H)、碳(C)、氧(O)的年平均值分别为(0.20±0.13)％、(0.48±0.11)％、(0.87±0.18)％、(2.56±0.76)％、(30.78±4.06)％、(16.42±5.17)％,与其他城市相比,S、N、Cl的含量较高。垃圾中的重金属铅(Pb)、镉(Cd)的年平均值分别为41.94mg/Kg和1.806mg/kg;汞(Hg)含量变化较大。焚烧后的灰渣中,Pb部分挥发,Cd得到富集,但几乎无Hg检出。

上海设施蔬菜主要品种污染物含量调查评估

通过对上海郊区单栋大棚、连栋大棚和现代化智能温室生产的叶菜类和茄果类设施蔬菜的主要品种污染物（农药和硝酸盐）含量抽样调查，并以附近大田蔬菜作为对照，分析结果发现，上海郊区设施蔬菜农药和硝酸盐的污染物含量普遍高于大地蔬菜，且超标状况比较严重。究其因，设施蔬菜生产较常规大田蔬菜生产农药与化肥使用水平高，而且在封闭环境条件下污染物降解速度慢，容易残留或积累超标。
