交通运输业可持续发展与ISO14000

运输业发展必须与环境协调统一，形成相互促进的良性循环；要实现良性循环，必须从技术和组织两个方面采取措施；推行ISO14000系列标准，是实施运输业可持续发展战略的一项重要措施。     

Practical environmental monitoring of major construction projects

Independent teams undertook environmental monitoring of particular concentrations of major construction projects forming part of Hong Kong’s U.S. $20 billion airport infrastructure programme located in dense urban areas. The team combination of environmental specialists with experienced civil engineers enabled pragmatic mitigation measures to be developed and accepted by the construction personnel with the result that potentially significant adverse impacts were averted. The authors discuss the mechanism and success of this innovative approach.     

淮海经济区核心区污染排放对重点区域城市PM2.5贡献研究

基于WRF-CMAQ空气质量模型，采用开关污染源排放的敏感性试验方法，定量分析了淮海经济区核心区污染排放对京津冀区域、"2+26 "大气污染传输通道城市、汾渭平原地区和长三角区域PM_2.5的贡献.结果表明，对京津冀区域，污染贡献比例最大值出现在10月份，同时对不同城市的贡献值在10%以内变化；对" 2+26"大气传输通道城市，影响的时空差异变化明显，其中对聊城市、菏泽市和济南市的贡献值均超过了10%；对汾渭平原地区的贡献总体较弱，最大贡献值低于5%；对长三角区域，贡献值在不同城市间的时空差异变化明显.考虑到淮海经济区地处京津冀和长三角过渡地带，且对京津冀和长三角区域PM_2.5影响较大，建议尽快将淮海经济区核心地区纳入国家大气污染重点控制区.

无铅汽油尾气颗粒物组分及其毒性研究

为研究无铅汽油的降铅效果。及其排出尾气颗粒物的有机提取物组分对小鼠细胞免疫功能的影响，采用大流量采样仪采集无铅汽油尾气颗粒物，用石墨炉原子吸收光谱法检测了颗粒物的铅含量，并采用气相色谱和质谱方法分析了颗粒物有机提取物的组分，同时，用凝胶电泳方法比较无铅汽油颗粒物的有机提取物在加铅和不加铅的条件下，对小鼠巨噬细胞的凋亡影响，结果显示，无铅汽油尾气排出颗粒物上仍有微量的铅，约为0.11mg/g。颗粒物有机提取物中含有大量的有害物质，如多环芳烃，杂环化合物等，通过凝胶电泳法显示，无论是有铅还是无铅，颗粒物有机提取物都能引起小鼠腹腔巨噬细胞的凋亡，在有铅的情况下，对巨噬细胞的凋亡影响更为明显，通过研究可以认为，无铅汽油对减轻汽车尾气的铅污染具有积极作用。但颗粒物上仍吸附大量的有害物质，对机体的免疫功能仍具有危害。

稀土元素镧对金鱼藻生长生理及细胞叶绿体结构的影响

研究了稀土元素镧对金鱼藻叶绿素总量、抗坏血酸氧化酶、过氧化氢酶、过氧化物酶等代谢指标和细胞叶绿体亚显微结构的影响，以及金鱼藻对镧的吸收积累作用，结果表明，短期内低浓度（２－１１０ｍｇ／Ｌ）的镧对金鱼藻生长有一定刺激促进作用，但随处理时间的延长及处理浓度的提高，抑制作用明显增强，并破坏细胞叶绿体结构；金鱼藻对镧有较强的吸收积累能力。     

Hydrogen storage and distribution systems

Hydrogen storage and transportation or distribution is closely linked together. Hydrogen can be distributed continuously in pipelines or batch wise by ships, trucks, railway or airplanes. All batch transportation requires a storage system but also pipelines can be used as pressure storage system. Hydrogen exhibits the highest heating value per weight of all chemical fuels. Furthermore, hydrogen is regenerative and environment friendly. There are two reasons why hydrogen is not the major fuel of toady’s energy consumption: First of all, hydrogen is just an energy carrier. And, although it is the most abundant element in the universe, it has to be produced, since on earth it only occurs in the form of water. This implies that we have to pay for this energy, which results in a difficult economic task, because since the industrialization we are used to consuming energy for free. The second difficulty with hydrogen as an energy carrier is the low critical temperature of 33 K, i.e. hydrogen is a gas at room temperature. For mobile and in many cases also for stationary applications the volumetric and gravimetric density of hydrogen in a storage system is crucial. Hydrogen can be stored by six different methods and phenomena: high pressure gas cylinders (up to 800 bar), liquid hydrogen in cryogenic tanks (at 21 K), adsorbed hydrogen on materials with a large specific surface area (at T < 100 K), absorbed on interstitial sites in a host metal (at ambient pressure and temperature), chemically bond in covalent and ionic compounds (at ambient pressure), oxidation of reactive metals e.g. Li, Na, Mg, Al, Zn with water. These metals easily react with water to the corresponding hydroxide and liberate the hydrogen from the water. Finally, the metal hydroxides can be thermally reduced to the metals in a solar furnace.
