标准石英粉尘及青石棉直接诱导8-羟基脱氧鸟苷加合物形成的研究

应用液相色谱结合电化学检测技术，研究了标准石英粉尘和青石棉体外诱导DNA分子氧化损伤产生加合物8－羟基脱氧鸟苷的形成与机制。结果表明，石英粉尘和青石棉均可致DNA分子氧化损伤并形成8－羧基脱氧鸟苷，但青石棉作用强于石英粉尘；石英粉尘的青石棉对H2O2氧化DNA的催化能力有较大差异。标准石英粉尘和青石棉，具有直接的遗传毒性；两者诱导DNA分子形成强致突变的8－羧基鸟苷可能是其潜在致癌机制之一。

城市交通机动车污染问题非常复杂，在许多不可控因素，城市交通是一个动态系统，污染物排放量始终处于变化之中，控制城市交通污染，必须严格控制机动车排放，该文介绍了国内外对城市机动车污染控制研究的概况，以及几种城市中污染物扩散的模型，展望了这方面研究前发展趋势，并提出了可持续发展的效能系统设计与管理的新概念。     

水中钡的卫生标准的探讨

本文对有关水中钡的毒性和标准的文献进行了复习和讨论。对钡的毒性和标准意见不一。有认为钡高至250mg／1无不良影响，而有的认为10mg／1以上即有毒性。我们的试验电得到类似后者的结果。建议饮水中钡的卫生标准订为0．1mg／1。地面水中钡的最高容许浓度为1mg／1。     

Chance-constrained programming (CCP)abatement of SO_2 emission for acid deposition control in Liuzhou City

A deterministic linear programming model which optimizes the abatement of each SO2 emission source, is extended into a CCP form by introducing equations of probabilistic constrained through the incorporation of uncertainty in the source-receptor-specific transfer coefficients. Based on the calculation of SO2 and sulfate average residence time for Liuzhou City, a sulfur deposition model has been developed and the distribution of transfer coefficients have been found to be approximately log-normal. Sulfur removal minimization of the model shows that the abatement of emission sources in the city is more effective, while control cost optimization provides the lowest cost programmes for source abatement at each allowable deposition limit under varied environmental risk levels. Finally a practicable programme is recommended.

Methodological and Practical Considerations for Developing Multiproject Baselines for Electric Power and Cement Industry Projects in Central America

The Lawrence Berkeley National Laboratory (Berkeley Lab) and the Center for Sustainable Development in the Americas (CSDA) conducted technical studies and organized two training workshops to develop capacity in Central America for the evaluation of climate change projects. This paper describes the results of two baseline case studies conducted for these workshops, one for the power sector and one for the cement industry, that were devised to illustrate certain approaches to baseline setting. Multiproject baseline emission rates (BERs) for the main Guatemalan electricity grid were calculated from 2001 data. In recent years, the Guatemalan power sector has experienced rapid growth; thus, a sufficient number of new plants have been built to estimate viable BERs. We found that BERs for baseload plants offsetting additional baseload capacity ranged from 0.702 kgCO2/kWh (using a weighted average stringency) to 0.507 kgCO2/kWh (using a 10th percentile stringency), while the baseline for plants offsetting load-following capacity is lower at 0.567 kgCO2/kWh. For power displaced from existing load-following plants, the rate is higher, 0.735 kgCO2/kWh, as a result of the age of some plants used for meeting peak loads and the infrequency of their use. The approved consolidated methodology for the Clean Development Mechanism yields a single rate of 0.753 kgCO2/kWh. Due to the relatively small number of cement plants in the region and the regional nature of the cement market, all of Central America was chosen as the geographic boundary for setting cement industry BERs. Unfortunately, actual operations and output data were unobtainable for most of the plants in the region, and many data were estimated. Cement industry BERs ranged from 205 kgCO2 to 225 kgCO2 per metric ton of cement.
