乌鲁木齐市大气中二氧化硫的灰色预测

根据灰色系统理论,联系乌鲁木齐市大气环境的实际状况,建立了精度检验为一级的灰色预测模型,经模型检验其精度完全满足要求。对乌鲁木齐大气中的SO2值进行预测分析的结果表明,乌鲁木齐市大气中SO2值呈上升的趋势,在未来几年中,乌鲁木齐市大气中SO2的预测值超过国家三级标准值(即大气中SO2的质量浓度年均值≤0.10mg/m3),这种发展趋势应引起有关部门的关注。     

水胺硫磷降解优势菌的筛选及其降解条件的研究

本文从已驯化好的活性污泥菌是悬液中分离筛选出水胺硫磷的降解优势菌，并对其降解条件进行了实验研究，当温度为２５℃，ＰＨ为６．５～７．５，水胺硫磷进水浓度１３５ｍｇ／Ｌ，停留时间为１２ｈ，在供氧条件下，水胺硫磷降解率可达７２．３％，而混合菌在最佳条件下，其水胺硫磷降解率为５５．８％，本文还要菌种进行了鉴定。     

南、黄海及青岛地区大气气溶胶中无机氮组分的研究

于2004年冬季在青岛地区采集了大气气溶胶TSP(总悬浮颗粒物)样品,并于2005年3月和5月航次采集了黄、南海TSP和安德森分级样品,分析了气溶胶中无机氮组分(NO2-、NH4 、NO3-)的浓度,探讨了相应区域大气颗粒物中各种无机氮离子的区域分布、粒级分布.青岛地区冬季TSP的月平均值为102.00～227.00 μg·m-3;黄海TSP浓度为80.00～130.00 μg·m-3,低于青岛地区;南海TSP浓度最低,在30.167μg·m-3以下.NH4 -N是南、黄海及青岛地区大气气溶胶中主要的无机氮组分,占到总无机氮含量的53.14%～94.72%;其次是NO3--N,占到总无机氮含量的4.75%～46.64%;NO2--N对无机氮的干沉降贡献很小,仅占不到0.54%.NO3--N的粒径范围较宽,多数呈现双峰分布,峰值出现在4.7～7.0 μm和2.1～3.3 μm范围内;NH4 -N的粒径分布范围较窄,主要集中于1.1μm以下的细粒子范围内;NO2--N性质不稳定,其分布比较复杂.近年来,汽车尾气排放量的增大增加了青岛地区大气气溶胶中NO3--N的含量.

Current status and research on E-waste issues in Asia

Rapid economic growth in Asia and the increasing transboundary movement of secondary resources will increasingly require both 3R endeavors (reduce, reuse, recycle) in each country and appropriate control of international material cycles. Recently, managing electrical and electronic waste (E-waste) has become an important target for domestic and international material cycles from the viewpoints of environmental preservation and resource utilization efficiency. To understand the current status of E-waste issues in the context of international material cycles and to discuss the future tasks related to achieving 3R in the region, we organized the National Institute for Environmental Studies (NIES) E-waste Workshop in December 2004. This article reviews past studies on E-waste and briefly describes the topics presented and discussions held at the workshop. The topics at the workshop included E-waste generation, recycling systems, international trade, and environmental impacts. In addition, we discussed various issues such as terminology, current environmental concerns, and possible solutions. Transboundary shipments of E-waste should be conducted taking into consideration the concept of sustainable development. The direction of future research and possible collaborations are also discussed.

Recycling and pollution control of the End of Life Vehicles in China

The quantity of vehicles has increased rapidly in recent years in China; however, the recycling of End of Life Vehicles (ELV) faces several problems and barriers including the collection difficulty and the environmental pollution caused by improper dismantling. In this paper, based on analysis of the basic situation regarding management and recycling of ELV in China, the ELV flow was introduced, and the potential ELV quantity was estimated. The current management regulations and policies were summarized, and dismantling and pollution control technologies for ELV recycling were introduced, too. It was suggested that with the rapid growth of ELV quantities, more regulations will be enacted, and the recycling network will be more effective; the dismantling technology and pollution control measures will be upgraded, and the recycling and remanufacturing industries will be more combined. The government should pay more attention to improve the management and supervision of, and encourage the development of, high level enterprises.
