苏南快速城镇化区域典型河道入河污染物调查分析与估算

针对快速城镇化区域产业快速发展、人口高度密集与排水设施建设滞后间的突出矛盾,以苏州官渎里区域的典型重污染河道——官渎花园内河为研究对象,在分析区域排污特征的基础上,系统总结点污染源、面污染源和内污染源在该类区域的具体表现形式和影响因素,对各类污染物入河量进行调查测算.根据测算结果,官渎花园内河的CODcr、NH3-N、TN和TP年入河量分别为222.54、11.16、16.63和2.56t·a-1.对各污染源贡献率的分析结果表明,工业污染和生活污染为主要污染源,其次为降雨径流污染.在上述测算分析的基础上,结合苏南快速城镇化区域发展特点,提出了若干河道污染控制的对策与建议.     

公众态度和机构监督对大气污染的影响

虽然以往对于环境库兹涅兹曲线（EKC）的研究中考虑了正式制度因素如政府机构监督，但是较少考虑非正式制度因素.本文重点检验两种制度情境的影响，微观层面的环境态度形成的非正式制度以及宏观层面的环保机构监督形成的正式制度对大气污染排放量的影响.基于CGSS2010-2013和2015年的数据库，从中提取出体现环境态度的问题，将其赋值指标化后，作为制度情境纳入环境方程.经过公开数据的收集，得到我国26个省份2010-2014年5年的面板数据.通过固定效应和随机效应模型，发现机构监督与人均GDP的交互项对氮氧化物、烟（粉）尘、二氧化硫排放都有影响，但是公众态度与人均GDP的交互项只对烟（粉）尘排放有影响，从而对不同制度情境下的环境库兹涅兹曲线进行了探索.     

Pond management in rural Bangladesh: problems and possibilities in the context of the water supply crisis

Today, Bangladesh is confronted with an immense water supply crisis: the decline of surface water bodies as well as a fall in the water table, together with the multiple pollution of the water in general, has put pressure on a precious resource that needs to meet the demand of a growing population. However, the most serious problem became public just four years ago—the contamination of the groundwater with arsenic. Considering the extent of the water supply problem, solutions for the future provision of safe drinking water are urgently needed. This article argues that ponds, a traditional water source in Bangladesh, could contribute to a solution. However, it is essential to recognise the problems and advantages of ponds in order to make suggestions on how to integrate ponds into the national water policy. Therefore, this paper analyses pond management—the use, maintenance and control of ponds—and its change from the past to the present. A holistic, dynamic and actor-oriented approach on a small scale was proved to be the appropriate instrument for this analysis.

飞灰螯合剂中挥发性污染物的释放

采集了4个市售飞灰螯合剂样品，分析其在20，40℃下挥发性污染物的释放规律.结果表明，释放的挥发性污染物主要有甲醛、乙醛、苯、异戊醛/异丙醇、甲硫醇、乙硫醇等；其中3个螯合剂样品甲醛的释放浓度在20℃为748~1325 μg/L-螯合剂，占释放的易挥发污染物的68%~96%（质量比），在40℃为4282~6822 μg/L-螯合剂，占释放的易挥发污染物的87%~95%（质量比）.随着温度升高，释放的挥发性污染物种类变多，部分污染物浓度增加，40℃时，4个螯合剂样品释放的易挥发污染物浓度比20℃时增加了142%~444%.元素分析、拉曼光谱和热重分析结果表明，4个螯合剂的主要有效成分相似，为二硫代氨基甲酸盐类物质.因此，推测这种飞灰螯合剂在稀释和飞灰稳定化过程中，对工作人员的健康可能有潜在的危害风险，应收集释放的气体并进行处理；且在飞灰填埋过程中，可能会导致渗滤液中NH₄⁺-N等物质的浓度升高，增加渗滤液的处理难度.     

The Frequency of Micronuclei among Newborns from Kragujevac, Central Serbia, after NATO Bombing in the Spring of 1999

Kragujevac, as an important industrial and economic center of the region, is now placed on the top of the list of environmentally endangered cities in our country. The aim of this biomonitoring study was to evaluate cytogenetic damage in a sample of newborns from Kragujevac after contamination of the environment entailed by the intensive bombing of the industrial zone of this city in the spring of 1999. The frequency of micronuclei (MN) in peripheral blood lymphocytes in a total of 61 phenotypically healthy newborns was analyzed before and after the NATO bombing. Analysis of micronuclei has been performed using the cytokinesis-block technique (CB MN test). Average MN frequency in lymphocytes of newborns before the bombing (N = 25) was 5.77 ± 0.85/1000 analyzed cells. After the bombing (N = 36), the average frequency of MN increased by a factor of 1.4 (8.11 ± 0.85), compared to the control frequency before the bombing. Statistical difference (p < 0.05) was established by Student's t-test. Our data suggest that such changes in genetic material were a direct consequence of contamination of the living environment.     

Scotch Pine Pollen under Conditions of Environmental Stress

Environmental conditions causing stress have a significant effect on the generative organs of Scotch pine. The parameters characterizing pine pollen are subject to significant interannual variations and are closely connected with weather and climatic conditions in the period of pollen formation. Airborne pollutants affect the quality of pine pollen, which is especially apparent in the years favorable for the formation of microspores. The ability of Scotch pine pollen to germinate and form pollen tubes in the regions with different technogenic loads proved to be significantly lower than in tree stands of the background areas.     

ENVIRONMENTAL AND ECONOMIC DAMAGE CAUSED BY SEDIMENT FROM AGRICULTURAL NONPOINT SOURCES1

Environmental and economic damages caused by agricultural nonpoint source inputs of sediment and associated pollutants are examined. Widespread water quality problems are identified in lakes, rivers, and estuaries in agricultural areas, and billions of dollars of on-site and offsite costs result from this eroded soil every year. Some water bodies have been irretrievably damaged, and expensive rehabilitation programs are needed to remedy in-place water pollution problems if Clean Water Act goals are to be achieved. Unless effective abatement and rehabilitation programs are established, billions of dollars of benefits to future generations will not be realized as more waters become irretrievably damaged, and billions more will continue to be spent by government to treat symptoms of these sediment-related problems.

云南三起地下洞穴金线鱼巴大暴发原因初探

2000年夏秋云南省3起地下洞穴金线Ba大暴发，主要是因为下水资源遭到山洪泥浆浸袭和水质被某些化学物质污染，造成严重缺氧所致，表明当前的环境保护工作还存在较多问题。
