Environmental Initiative Prioritization with a Delphi Approach: A Case Study

India is fast finding its place in the industrialized world and that is beginning to raise its environmental consciousness. The Delphi technique was used to prioritize specific needs and articulate a sustainable urban improvement strategy for the city of Mumbai (formerly Bombay). The Delphi technique is a means of achieving consensual validity among raters by providing them feedback regarding other raters' responses. Mumbai has several indigenous environmental groups that were tapped for activists and leaders; the study was conducted using ten environmentalists. In the initial phases the responses resulted in a range of possible program alternatives. The last two stages helped to seek out information that generated a consensus on the part of the respondent group. Statistical analysis methods included a hierarchical cluster analysis, mean, median, mode, and percent of agreement calculations using SPSS software. The face-to-face discussion in phase 4 clarified some issues and helped the group as a whole to outline the strategy for putting in place the essential elements of a framework to improve the quality of life in an urban environment.     

Mapping of temperature and line-of-sight errors in constituent retrievals for MIPAS/ENVISAT measurements

An optimized code for the near real-time retrieval of line of sight, temperature and volume-mixing ratio profiles of five key species (O₃, H₂O, HNO₃, CH₄ and N₂O) from infrared limb spectra recorded by the Michelson Interferometer for Passive Atmospheric Sounding (MIPAS) experiment on board the ENVISAT-1 satellite was developed as part of an ESA-supported study. In this code line of sight and temperature are retrieved simultaneously among themselves, but sequentially with respect to the volume-mixing ratio of the five key species. The sequential retrieval leaves unaccounted the mapping of line of sight and temperature errors in the retrieved volume-mixing ratio of the constituents. This paper illustrates an algorithm that provides the a-posteriori evaluation of temperature and line-of-sight-induced error on the retrieved volume-mixing ratio of the MIPAS key species. It is shown that in most cases temperature and line-of-sight-induced error provides a significant contribution to the total volume-mixing ratio error. The variability of this error as a function of latitude, season and atmospheric model is also analyzed.

环境监测中的新工具--酶免疫检测技术

酶免疫检测技术，是根据抗原抗体反应具有高度的特异性，将酶标记物的抗体作为标准试剂来鉴定未知的抗原。ＥＩＡ技术是环境污染物筛选试验的良好工具，其与气相色谱。高效液相色谱结合，能极大地提高环境监测能力。将酶联免疫吸附检测试剂盒在环境监测中的应用结果，与ＧＣ，ＨＰＬＣ等传统分析方法相比，具有良好的相关性。     

江苏省工业污染排放特征及其成因分析

采用环境库兹涅茨曲线模型模拟江苏省1991年以来经济增长和工业污染之间的动态演进关系,应用分解分析法对2001～2004年间部分污染物排放变化的成因进行了定量分析.结果表明,江苏省工业污染排放量和人均GDP之间的关系类型有U型、倒U型、U型+倒U型以及N型4种,目前大部分污染物呈增长态势.将污染物排放变化的成因分为规模效应、结构效应和广义技术效应3类,结果显示,规模效应促进污染物排放量增加,结构效应和广义技术效应的作用方向不确定,但广义技术效应对污染物控制有决定性作用,强力的环境政策和管理措施能够有效地控制污染物排放.     

Electricity consumption: The growth pattern as an ecological indicator

Ecological problems are mainly caused by growth processes. The energy input is a key indicator for ecosystems. In this context, the use of the most valuable kind of energy is of special importance. Economic systems may be considered as special ecosystems. The most valuable kind of energy used in economic systems of industrialised countries is electricity. For some industrialised countries the growth pattern of electricity consumption and its relation to the gross domestic product is considered in this contribution. A linear relation between both indicators for about 3 decades after the Second World War and a coupling of these indicators starting at 1973 has been found. The aim of the contribution is to present this relation and to initiate a discussion about its reason and its interpretation.
