日照市大气质量指数分区预报

利用1999年1月至2002年7月日照市环境监测站监测的污染物浓度资料和探空及本站地面气象资料,分析了日照地区可吸入颗粒物(PM_(10))、二氧化硫(SO_2)、氮氧化物(NO_x)浓度变化的时空分布特征及气象要素的变化对污染物浓度时空分布特征的影响。在此基础上,建立了可吸入颗粒物(PM_(10))、二氧化硫(SO_2)、氮氧化物(NO_x)浓度指数预报方程及大气质量指数分区预报流程。并用VB6.0语言编程在微机上建立了简洁流畅、操作简便的大气质量指数分区预报系统。实际预报结果较好。

How and why is Aquatic Quality Changing at Nahanni National Park Reserve, nwt, Canada?

Nahanni National Park Reserve is located at southwestern NWT-Yukon border. One of the first UNESCO World Heritage sites, Nahanni lies within Taiga Cordillera and Taiga Shield Ecozones. Base and precious metal mining occurred upstream of Nahanni prior to park establishment. Nahanni waters, sediments, fish, and caribou have naturally elevated metals levels. Baseline water, sediment and fish tissue quality data were collected and analyzed throughout Nahanni during 1988–91 and 1992–97. These two programs characterized how aquatic quality variables are naturally varying in space and time, affected by geology, stream flow, seasonality, and extreme meteorological and geological events. Possible anthropogenic causes of aquatic quality change were examined. Measured values were compared to existing Guidelines and site-specific objectives were established.

An integrated assessment model for cross-country pipelines

The cross-country petroleum pipelines are environmentally sensitive because they traverse through varied terrain covering crop fields, forests, rivers, populated areas, desert, hills and offshore. Any malfunction of these pipelines may cause devastating effect on the environment. Hence, the pipeline operators plan and design pipelines projects with sufficient consideration of environment and social aspects along with the technological alternatives. Traditionally, in project appraisal, optimum technical alternative is selected using financial analysis. Impact assessments (IA) are then carried out to justify the selection and subsequent statutory approval. However, the IAs often suggest alternative sites and/or alternate technology and implementation methodology, resulting in revision of entire technical and financial analysis. This study addresses the above issues by developing an integrated framework for project feasibility analysis with the application of analytic hierarchy process (AHP), a multiple attribute decision-making technique. The model considers technical analysis (TA), socioeconomic IA (SEIA) and environmental IA (EIA) in an integrated framework to select the best project from a few alternative feasible projects. Subsequent financial analysis then justifies the selection. The entire methodology has been explained here through a case application on cross-country petroleum pipeline project in India.

厦门港和员当湖表层沉积物中的石油烃和多环芳香烃

2002年4月厦门港沿岸设9个站，员当湖设两个站采集表层沉积物，用有机溶剂萃取，硅胶柱色层分离，气相色谱—质谱联机带SIM数据采集系统对样品的石油烃类(M／Z=55)，多环芳香烃类进行分析，结果显示员当湖石油烃和多环芳香烃质量分数分别高达1397和1376．5ng／g。厦门港船只活动，厦门港四周工业废水、车辆燃油滴漏是石油烃和多环芳香烃污染的主要来源。
