POLITICAL PARTICIPATION AND WATER RATES: A REPLY1

ABSTRACT: Mercer and Morgan provide several valid criticisms of a previous analysis on political influence and water rates. More sophisticated statistical analyses may be justified given the high degree of interdependence among regulated firm variables. Theoretically, there are numerous measures of political activity superior to the one employed in the original analysis; however, data unavailability precludes their use. A better (and yet practical) measure of consumer leverage may be relative dominance by a specific political party. Until relatively easy access is obtained to municipal election data, the possible political variables that can be employed in more elegant analyses are few in number, and each has theoretical limitations.     

PROBABILISTIC GREAT LAKES HYDROLOGY OUTLOOKS1

ABSTRACT: The Great Lakes Environmental Research Laboratory developed a semiautomatic software package for making hydrological outlooks for the Great Lakes. These include basin moisture storages, basin runoff, lake heat storage, lake evaporation, heat fluxes, and net lake supplies, one or more full months into the future. The package combines GLERL's rainfall-runoff and lake evaporation models with near real-time data reduction techniques to represent current system states. Users select historical meteorologic record segments as candidate future scenarios to generate deterministic near real-time hydrological outlooks. GLERL has extended the package to make probabilistic outlooks for a decision-maker who must estimate the risk associated with his decisions. GLERL matches National Weather Service meteorologic outlook probabilities by selecting groups of historical meteorologic sequences, and constructs embedded outlook intervals for each hydrologic variable of interest. Interval probabilities are assigned from comparisons over a recent evaluation period. This physically-based approach for generating outlooks offers the ability, as compared to other statistically-based approaches, to incorporate improvements in the understanding, of process dynamics as they occur in the future and to respond reasonably to conditions initial to a forecast (such as heat and moisture storages), not observed in the past.     

4－AAP萃取光度法以蒸馏水代替无酚水测定地面水中挥发酚

４－氨基安替比林（简称４－ＡＡＰ）萃取光度法测酚是灵敏度很高的标准分析方法。该方法要求使用无酚水。本文经过实验分析提出以蒸馏水代替无酚水测定地面水中挥发酚，结果表明，本方法检出限为０．０１７ｍｇ／ｌ，具有较高的精密度和准确度。本法省略了制备无酚水的程序，从而使实验分析得到简化。

南亚热带丘陵土壤水分循环及其有效性的研究──Ⅵ.丘陵赤红壤-果树-大气连续体中能量的变化及其分布规律

依据田间实测资料,分析了南亚热带丘陵赤红壤-果树-大气连续体中的能量变化及其分布规律、结果表明,土壤基质势的年度变化特征说明南亚热带丘陵赤红壤存在明显的湿季和旱季．果树叶水势随土壤基质势、大气水势、气温及大气相对湿度的变化而变化,荔枝、龙眼叶水势的变化比芒果叶水势的变化大.以荔枝、芒果和龙眼作为供试植物,水分从土壤到达植物根表皮、进入根系并通过植物茎到达叶片,其能量降低分别约为0．9063～1.7428、0．2818～0．6979和0．2904～1．8707MPa;水分从叶部汽化扩散到大气中,其能量降低分别达15．1491～57．3669、15．4491～58．4036和14．5824～56．9536MPa,说明水流在南亚热带丘陵赤红壤-果树-大气连续体中运移时,其能量主要消耗在由叶部到大气这一环节上。     

长江下游重点江段水质污染及对鱼类的毒性影响

通过对长江下游安庆、南京、镇江、南通４江段水质污染及其对鱼类毒性影响的调查监测可发现,长江下游江段主航道水质较好,符合国家地面水Ⅱ类水质标准．但近岸带水质由于受污染带的影响,水质污染较严重,其主要污染物为石油类和挥发酚等．上述这些污染物质对鱼类具有一定的毒性影响,其不但可引起鱼类的急性中毒,而且可诱发鱼类产生微核,并对鼠伤寒沙门氏菌ＴＡ９８菌株表现出一定的致突变性．同时在上述几个江段鱼体内可检出较高的蓄积性污染物的残留量．研究结果显示,长江下游江段正在遭受沿江诸多工业废水的污染,尤其是污染带的作用,并且这种污染对区域性渔业有一定的影响     

An evaluation of legislative measures on electrical and electronic waste in the People's Republic of China

With the increasing number of recycling mishaps in connection with waste electronic and electrical equipment (WEEE) in the People's Republic of China, it is imperative that the handling and recycling of WEEE be sufficiently regulated in China. Regulations covering three major issues, namely, take-back issues, controls on hazardous substances in WEEE and the assurance of good environmental management in WEEE plants, were promulgated between 2006 and 2008. The evaluation in this country report shows that few of these regulatory measures have performed satisfactorily in terms of enforcement, of public acceptance and of environmental concerns. In brief, the take-back requirements and the associated financial responsibilities are only vaguely defined; the control on hazardous substances and the so-called "environmental expiry date" requirements cannot be properly enforced, and the resources needed to ensure the satisfactory enforcement of the environmental abatement and pollution control requirements in WEEE plants are overwhelming. In addition, the use of a "multiple enforcement body" approach to the control of hazardous substances in WEEE is an indication that the Chinese government lacks the determination to properly enforce the relevant legal requirements.
