Inventory of emissions from major air pollutant categories in Turkey

In this study, an inventory of air pollutant emission estimates from major air polluting sources in Turkey for period between 1985 and 2005 with 5-year intervals were estimated. Inventory covers anthropogenic sources of five major air pollutants of particulate matter, sulfur dioxide, carbon monoxide, nitrogen oxides and non-methane volatile organic compounds. Their break-down with respect to main activity sectors were shown and their distribution by the largest industrial source categories were worked out as annual estimates. This inventory and its analysis point to serious environmental implications of air pollutants and a need to develop a policy plan for reducing these emissions.     

First-trimester prenatal diagnosis of severe alpha-thalassemia

By means of chorion biopsy together with restriction endonuclease analysis of fetal DNA, first trimester diagnoses were successfully made in 33 fetuses at risk for Bart's hydrops fetalis. Seven pregnancies with Hb H or hydrops fetalis were therapeutically terminated before 4 months of gestation. Of the 26 pregnancies intended to continue, 18 have come to term with normal deliveries; one with threatened abortion was terminated at the end of the first trimester and, seven are progresssing normally.     

“十五”环境规划编制方法的改革

在分析中长期环境规划发展趋势的基础上,结合可持续发展的要求,从6个方面探讨了“十五”环境规划编制方法的改革与创新的具体方案。     

战略环境评价方法学研究

通过对国内外开展战略环境评价实施的研究，分析了战略环境评价程序中各个阶段的主要内容与方法，项目环境影响评价与战略环境评价在方法学上的异同，提出了我国在战略环境评价起步阶段方法研究应注意的方面。     

Practical environmental monitoring of major construction projects

Independent teams undertook environmental monitoring of particular concentrations of major construction projects forming part of Hong Kong’s U.S. $20 billion airport infrastructure programme located in dense urban areas. The team combination of environmental specialists with experienced civil engineers enabled pragmatic mitigation measures to be developed and accepted by the construction personnel with the result that potentially significant adverse impacts were averted. The authors discuss the mechanism and success of this innovative approach.     

钢铁废水混凝处理试验研究

通过某钢铁公司废水处理研究试验,采用不同混凝剂和阴阳离子型聚丙烯酰胺(PAM)助凝剂,对不同时间段的废水进行混凝试验,确定最佳加药量和最佳混凝剂。试验表明,硫酸铝对油、全铁和COD等的去除率相对较高,且具有不需投加助凝剂PAM、适用性强等优点。     

湿式氧化技术处理炼油厂碱渣废水

考察了湿式氧化法处理运行过程 ,以及相关参数的控制方案。在实现装置出水、废气达标排放的前提下 ,稳定控制装置运行是可以实现的。如后续有酸化除酚工艺和SBR工艺进行再处理 ,则应选用温度 (14 5± 5 )℃ ,压力控制在 0 6～ 0 .7MPa的湿式氧化法     

邢台煤矿矿井水的综合治理及利用

随着开采深度及范围的扩大，邢台煤矿井下高压出水点越来越多，既浪费了大量的排水费用，又对岩溶水环境和水资源造成了严重破坏。针对上述情况，用四种不同的方法分别进行了封堵和重新利用，使矿井减少了４８０ｍ＾３／ｈ的无效排水，经济效益和环保效益均十分明显。     

厌氧酸化-二级PSB流化床工艺处理高浓度有机废水

采用厌氧酸化+二级光合细菌(PSB)流化床的组合工艺对植物压榨发酵废水进行降解实验,一级流化床(PSB1)中填料为轻质多孔炭渣,二级流化床(PSB2)为活性炭,扰动方式分别采用机械流化和机械气动组合流化,稳定运行40d。结果表明,进水酸化12h后CODCr由80000~120000mg/L降至63000~95000mg/L,进而由系统出水回流稀释至8000~12000mg/L,进入二级流化床反应器,PSB1白天厌氧光照、夜间微好氧,PSB2白天微好氧、夜间好氧,停留48h,CODCr降至295.8~384mg/L,稳定实现96.2%以上的CODCr去除率,TN去除率为71.3%。
