采用气相色谱法和电子捕获检测技术,对1999和2005年繁育季节结束时在意大利罗马周边地区采集的未能孵化的红隼(falco tinnunculus)卵进行研究,得出多氯联苯(PCB)、滴滴涕(DDT)及其衍生物和其他有机氯化合物的浓度。结果表明,在所有的PCBs中,同类物153和180所有被测卵中均有检出,且浓度最高。相同鸟巢不同年份收集的卵中含有的PCB同类物类型和数量相似。本研究发现硫矿附近的隼卵中含有非典型性的低氯同类物,该结果有力地支持了地中海和欧洲大陆的成年红隼仅进行短距离迁徙或不迁徙的结论,即暗示着隼卵污染物来自于当地环境。研究还发现同一窝中不同卵中的PCBs类型相似,但浓度却随着产卵的时间顺序延伸而不断降低。

猛禽监测计划是一项长期的(40年以上)、遍及英国的暴露监测计划,目的是确定猛禽肝脏和卵中指定杀虫剂和污染物的浓度。本文描述了猛禽监测计划的工作过程,尤其侧重描述其中一些用以监测猛禽体内污染物的重要科学和政策动因,以及猛禽监测计划的特别目标、范围和方法。我们还发布了过去未曾发表的数据,这些数据充分说明猛禽监测计划在逆转化学污染物产生的影响中是一项成功的缓解措施,且猛禽监测计划能够确定并评估化学物质对具有高保护价值物种的风险,并最终宣告和提炼出监测方法理论。另外,我们讨论了这项计划如何用于更广泛的保护需求。

就能源使用和碳足迹来说,炼铁和炼钢这类初级加工过程往往引起人们的极大关注。而轧制工序,虽然对能源需求很大,但钢铁企业在考虑自身的环境责任和节能机会时,却往往会将其忽略。初级加工过程相比于成品加工过程,能耗高,而且具有重要的影响。绿色轧制的关键主要在于收得率(和避免废品重熔),它就像能源的直接利用一样重要。以意大利阿维迪的全无头带钢生产(ESP)厂的设计和调试项目为案例,介绍现代化轧机如何为绿色钢铁工业做贡献。技术的有关特点包括近终形连铸和直接轧制及取消中间加热所带来的节能效果,传动和能量转换技术的进步,通过收得率最大化而实现节能的方案。还介绍了一些以绿色轧制为宗旨的重要的合作,包括与大学的合作,特别是剑桥大学的WellMet2050项目。作为结论,归纳了一般工业中使用钢铁的绿色原则,为设计打开重要思路。

An atmosphere-only model system for making seasonal prediction and projecting future intensities of landfalling tropical cyclones(TCs)along the South China coast is upgraded by including ocean and wave models.A total of 642 TCs have been re-simulated using the new system to produce a climatology of TC intensity in the South China *** comparisons of the simulations from the atmosphere-only and the fully coupled systems reveal that the inclusion of the additional ocean and wave models enable differential sea surface temperature responses to various TC characteristics such as translational speed and *** particular,interaction with the ocean does not necessarily imply a weakening of the TC,with the coastal bathymetry possibly playing a role in causing a near-shore intensification of the *** results suggest that to simulate the evolution of TC structure more accurately,it is essential to use an air-sea coupled model instead of an atmosphere-only model.

Progress in Natural Science:Materials International 2004年第9期 49-55+98页

作者： James f.Lynch,Timothy f.Duda Woods Hole Oceanographic Institution MA02543 1053 USA Woods Hole Oceanographic Institution MA02543 1053 USA

Two conclusions are obtained by analyzing the fluctuation data of the temperature field and the sound transmission in the South China Sea from ASIAEX 2001 volume interaction experiment. first of all, the peak to peak value of the particle vertical mean displacement due to the internal waves exceeds 40 m. Secondly, the peak to peak value of the sound transmission fluctuations represented by the pulse leading edge fluctuations of the travel time average exceeds 100 ms. Based on that, the major components of the internal waves are obtained by analyzing the spectrum of the temperature field fluctuations. The spectrum structures of the temperature field fluctuations in the across shelf and the along shore directions are compared respectively, and the spectrum structures of the sound transmission in such two different directions are also compared. The multi path signals and the travel time of the pulse are respectively used to capture the information of the sound transmission fluctuations, and their spectrum structures are compared also.
