地面水中叶枯灵的高效液相色谱测定

本文采用反相高效液相色谱法，在质控条件下，对河水，塘水两种地面水中叶枯灵的检验方法进行了测试，用Shimapck ODS柱为分析柱，以甲醇：水＝50：50为流动相，并用冰醋酸调PH至4－5，紫外检测波长281nm，两种水样的平均回收率分别为91．7－96．3％，90－95．8％，相对标准偏差为4．3％，最低检出限为0．0261mg/l，为地面水中叶枯灵卫生标准的实施提供了简便，灵敏，正确的配套测试手段。

DSD酸氧化缩合废水浓缩液回用试验研究

研究了DSD酸氧化缩合废水浓缩液回用到原生产过程的可行性。对DSD酸氧化缩合废水可采用萃取技术分离出其中97％的有机物，反萃产生的4－8倍的浓缩液返回到DSD酸生产中的氧化缩合单元后，可提高DNS酸的收率约7．43％，且不会明显影响产品的纯度，浓缩液8次循环磁用试验的结果表明，虽然DSD酸氧化缩合废水的COD从15000－20000mg/L提高到20000－29000mg/L，但没有显著持续增长的趋势，表明反应液中副产物的浓度得到了有效的控制。

Deposition and Storage of Spheroidal Carbonaceous Fly-Ash Particles in European Mountain Lake Sediments and Catchment Soils

Spheroidal carbonaceous particles(SCPs) are produced only from high temperaturecombustion of fossil-fuels. In mountain lakesystems, they provide an unambiguous indicator ofatmospheric deposition. In order to comparedepositional fluxes of SCPs between mountainareas experiencing various pollutant regimes,intensive bulk deposition sampling was undertakenat five sites across Europe. Catchment soil coresand lake sediment cores were also taken at eachsite to compare SCP storage over the post-industrial period. Atmospheric, sediment and soilSCP data showed similar patterns. Highestcontamination was found in Scotland, Slovakia andSpain with the Austrian site intermediate and themid-Norwegian site least contaminated. A highproportion of accumulated SCPs were found to bestored in catchment soils at each site.Therefore, a significant increase in soilerosion, possibly as a result of future climatechange, could lead to the input of largequantities of catchment stored SCPs and, byimplication, other atmospherically depositedcontaminants to the lake ecosystem.     

Phytoremediation of industrial sludge using vegetation‐assisted dewatering

With the emergence of risk‐based corrective action decisions, there is interest in the use of more natural techniques that may be as protective as the traditional removal, landfill, or capping approaches for impoundment closure. The use of phytoremediation is one of the more promising techniques. This article presents the results of a three‐year field‐pilot phytoremediation study that involved the use of plants to enhance sludge dewatering at an inactive natural gas‐cracking wastewater lagoon. The dewatering was accompanied by contaminant reduction of benzene, toluene, xylene (BTX), and naphthalene concentrations to below the cleanup goals. Meanwhile, the concentration reductions of three or more ring polynuclear aromatic hydrocarbons (PAHs) varied between 30 percent and 60 percent, except for dibenz[a,h]anthracene. The residual PAHs in the sludge are not leaching. Parallel laboratory studies suggest a reduced PAH availability and mobility in the unsaturated zone sludge. © 2002 Wiley Periodicals, Inc.
