Particle concentration effect in adsorption/desorption of Zn(Ⅱ) on anatase type nano TiO_2

Adsorption/desorption in a new Zn(Ⅱ)-TiO_2 adsorption system was investigated at different particle concentrations(C_p).TEM,SEM and XRD analyses revealed that the TiO_2 particles were an aggregation of nano-sized(approximately 10 nm)pure anatase-type TiO_2. Adsorption experiments were carried out with particle concentrations of 100,400 and 1000 mg/L,and their adsorption isotherms were found to decline successively,showing an obvious C_p effect.Desorption experiments indicated that adsorption in this system was irreversible,and the irreversibility increased with increasing C_p.These phenomena could be explained by the MEA(metastable equilibrium adsorption)theory and the C_p effect could be modeled well with an MEA-Freundlich-type C_p effect isotherm equation. This study may help understand environmental behavior of contaminants on ultrafine natural particles.     

Conflictive sustainability landscapes: the neoliberal quagmire of urban environmental planning in Buenos Aires

The government of Canada ratified the Kyoto Protocol on 17 December 2002, but over 100 Canadian municipalities had joined the International Council for Local Environmental Intitatives' (ICLEI) Cities for Climate Protection (CCP) campaign up to a decade earlier. A low-cost home energy rating system (HERS) evaluation and individualized energy plan was provided to 420 households in Kitchener, Ontario, from September 2000 to August 2001. To assess the impact of the energy efficiency program, natural gas consumption in the year prior to the evaluation was compared with that in the year following. Overall, a 5% reduction was achieved, but individual responses varied widely. Situational and psychological factors were evaluated for three groups of households: the conservers, the consumers and the steady middle group. Conservers (30% of households) had higher initial energy consumption levels and achieved two-thirds of the potential savings identified by the energy evaluation. Consumers (12% of households) had higher ownership rates of high-efficiency furnaces and water heaters and demonstrated the rebound effect of increased demand for energy services following the evaluation. Low-income groups were the most likely to behave as conservers (42%) while high-income groups were the least likely to be conservers (13%) and the most likely to be consumers. Local programs need to be inclusive of all income groups to increase participation and implementation rates by systematically reducing barriers (financial, knowledge, trust) or increasing incentives (financial, regulatory or social) if the desired goal (e.g. Kyoto target) is to be achieved.     

秦皇岛市居民生活和公用事业用水量预测

本文在对“九五”期间秦皇岛市城市生活、公用事业水情况认真分析的基础上,按秦皇岛市“十五”计划和2010年远景目标对秦皇岛市2005年和2010年未来城市生活需水量和城市公用事业用水量进行了预测;同时对2020年和2030年进行了展望;综合分析预测的结果,提出了节水的建议,并对需水量的零增长期进行了预期分析。本文的研究结果对秦皇岛市水资源可持续利用及国民经济和社会发展规划的制订有积极的意义。

物流分析模型在环境问题研究中的应用

当前经济研究中对环境问题越来越重视，已经有多种不同方法可以用来研究材料和物质流在经济中的运转，物流分析模型（SFA）就是其中一种。本文将SFA应用于一个单一的，假设的污染问题中，这样以实践的方式来评价模型的结果。结果显示，SFA模型能够发现潜在的或预料不到的物质流和排放物，并能发现在将来某一时候会引起经济和环境问题的积累。
