不同气氛下燃煤SO2的排放规律研究

在立式管状电加热炉上对合山高硫煤在不同的气氛、温度以及Ca／S比的条件下进行了动态燃烧实验，对收集的气体产物进行了红外光谱分析，并讨论了CO2浓度以及温度等因素对SO2释放的影响。结果表明：不同浓度的CO2气氛对煤燃烧过程中硫的释放以及石灰石的固硫效率有着不同的影响，在高于900℃以后，较之空气气氛下，无论是否存在钙基固硫剂，其它三种02／C02气氛下S02的排放量都比较低，且在不同C02浓度下，温度对S02的排放影响不一致。

销毁遗弃化学武器的环境风险评价方法研究

为履行《禁止化学武器公约》，各缔约国销毁化学武器的工作已启动。根据当前世界上化学武器的销毁情况，并针对二战期间在中国遗弃的化学武器的特点，给出了一套适应化学武器销毁流程的环境风险评价方法和技术。这套方法对将在我国进行的销毁遗弃化学武器风险评价工作有一定的实际意义。     

定量风险评价标准探讨

围绕定量评价标准对风险的度量和制定风险评价标准的基本原则等方面的进展和存在的问题进行了初步的探讨，分析归纳了国处有着的个人风险和社会风险标准，提出具有重大危害性的工业设施对员工或公众造成的风险，不应显著高于人们在日常生活中接触到其他风险；每年１０＾－６的死亡风险是可以忽略不计的个人风险水平等观点。     

准确测定高锰酸盐指数考核样的方法

根据长期的实际操作经验，要准确测定高锰酸盐指数值，在样品分析中，水浴时间不能少于35min；K值在0．980-1．010；滴定时温度保持在70℃。以提高测定结果的准确度。     

环境影响评价中的"风险评价"实例

Biogenic VOCs emission inventory development of temperate grassland vegetation in Xilin River basin, Inner Mongolia, China

Given the key role of biogenic volatile organic compounds(VOCs) to tropospheric chemistry and regional air quality, it is important to generate accurateVOCs emission inventories. However, only a less fraction of plant species, in temperate grassland of Inner Mongolia, has been characterized by quantitative measurements. A taxonomic methodology, which assigns VOCs measurements to unmeasured species, is an applicable and inexpensive alternation for extensive VOCs emission survey, although data are needed for additional plant families and genera to further validate the taxonomic approach in grassland vegetation. In this experiment, VOCs emission rates of 178 plant species were measured with a portable photoionization detector( PID). The results showed the most of genera and some families have consistent feature of their VOCs emission, especially for isoprene, and provide the basic premise of taxonomic methodology to develop VOCs emission inventories for temperate grassland. Then, the taxonomic methodology was introduced into assigning emission rate to other 96 species, which no measured emission rates available here. A systematical emission inventory of temperate grassland vegetation in Inner Mongolia was provided and further evidence that taxonomy relationship can serve as a useful guide for generalizing the emissions behavior of many, but not all, plant families and genera to grassland vegetation.     

Methods for project-based mechanisms (JI/CDM)—relevance of IPCC inventory guidelines

A baseline for a project consists of estimates of annual emissions of greenhouse gases (GHG) for a given time period without implementing the project. A general three-step process for determining the baseline is suggested. The emission reduction of the project is given by the difference between the baseline and the monitored annual emissions. A preferred method, direct measurement of the emission reduction, is possible for some types of projects. Methods for estimating the annual baseline emissions are not necessary for the latter category, and a definition of this project category is suggested. IPCC Guidelines for National GHG Inventories categorise the emission sources so that only direct emissions from consumption of fuel and feedstock are calculated. There are thus no emission factors for indirect emissions (e.g. electricity consumption or km transported) or emission factors that depend on technology only, independent of consumption of fuel and feedstock. Technology-dependent emission factors may thus need to be developed for estimating indirect emissions and multi-project baselines. Consistency should be sought with the IPCC Guidelines when estimating annual baseline emissions and in monitoring project emissions to ensure comparability with the National Inventories.     

刍议排污权价格的合理界定

排污权交易在中国的试点过程中,显现了强大的生命力,然而,由于对排污权交易基础理论理解的偏差,导致了实践层面上的缺陷,如排污权初始分配是否应该有偿的问题;排污权商品再分配价格应不应该包括正的外部效应价值问题;在排污权交易制度改革与中国其他制度的改革(现行税制改革、绿色GDP的推行)进行中出现的不协调的问题.
