上海市在用车推行I/M制度中检测方法的研究

对在用车实施I/M制度，采用底盘测功机模拟道路工况检测汽车排放污染物，按美国国家环保局（EPA）推荐的方法有3种：瞬态短工总法（IM240）、稳态加速模拟工况法（ASM）和瞬态短工部简易质量分析检测法（VMAS）。根据上海市的试验结果，对上述3种方法的检测精度、设备投资以及运行维护诸方面进行分析比较，阐明上海市采用VMAS方法的依据和应注意的问题，并对应采用的模拟道路工况提出了看法。     

在用车I／M制度的脆性及脆性源研究

I／M制度作为一个系统存在着脆性源,如果该制度在运行过程中控制不好脆性源,则其有效实施将受到影响。利用系统脆性理论对该制度进行分析研究找出L／M制度系统的脆性源以及解决措施是其分析研究的目的。在系统子因子中从业人员素质、仪器设备是最大的脆性源,但是其均被维修企业和检测企业所包含。综合分析研究结果显示,由于其在维修企业的脆性度比在检测企业的脆性度大,所以维修企业是该制度最重要的脆性源。用系统脆性理论分析方法分析I／M制度的脆性是一种科学、有效和实用的方法,具有较好的应用前景,为保障更好的运行I／M制度以有效的控制在用车的排放提供了理论依据。     

快速高效去除微囊藻的GO/QPEI复合纳米材料

本研究合成了一种新型高效的去除铜绿微囊藻(Microcystis aeruginosa)的氧化石墨烯/季铵盐聚乙烯亚胺(GO/QPEI)纳米复合材料.GO/QPEI在pH为4~10的条件下都具有高效去除M.aeruginosa的能力,其去除能力在2 min内可达96%以上.GO/QPEI对微囊藻的吸附更符合Freundlich方程,最大吸附量为5.58×1011cells·mg-1.吸附动力学表明GO/QPEI的假二级吸附反应.GO纳米片和QPEI的协同效应是其高效去除微囊藻的主要机制.

广州市白云山降水的化学特征及源解析

以2006年广州市白云山降水监测资料为基础,对其降水样品的化学特征进行了分析。结果表明,白云山降水样品pH值分布为3.04—6.41,雨量加权pH平均值为4.26,酸雨频率为70.2％,降水中的主要阳离子是Ca^2＋和NH^＋4分别占阳离子总量的46.4％和17.5％;主要阴离子为SO^2-4和NO^-3,分别占阴离子总量的59.0％和19.9％。相对酸度（FA）和中和因子（NF）计算结果表明,约有84.7％的降水酸度被碱性成分Ca^2＋和NH^＋4中和。利用富集系数方法,计算结果表明SO^2-4和NO^-3主要来源于人类活动,而Ca^2＋和K^＋主要来源于岩石／土壤风化。     

橡胶促进剂M盐废水生物处理技术研究

为探讨微生物技术在橡胶促进剂M盐废水处理中的应用,利用高效优势蘸强化A2O工艺对橡胶促进剂M盐废水进行处理,整个系统运行过程分为污泥的培养与驯化阶段及稳定运行阶段。在稳定运行阶段COD0平均去除率达90．71％,氨氮平均去除率达78．31％。以Mn^2＋、Fe^2＋、Mg^2＋、Ni^2＋为4个影响因子,通过正交实验分析无机离子对橡胶促进剂M盐废水中有机物降解的促进作用。由实验数据的摄差大小可知,各无机离子对优势复合菌降解橡胶有机废水的影响从大到小依次为：Mn^2＋、Fe^2＋、Ni^2＋和Mg^2＋。4种离子最佳质量浓度组合为：0．500mg／L的Mn^2＋、1．00mg／L的Fe^2＋、35．0mg／L的Mg^2＋和0．025mg／L的Ni^2＋。     

Mining and social development: Refocusing community investment using multi-criteria decision analysis

This paper addresses the question: How can mining companies assess social investment projects so that projects create value for the company and communities in which they operate? Mining companies are still wrestling with the limits of their responsibility in relation to social development even though they accept the business case for community investment at a general level. Fully aware of the practical hazards involved in taking an active role in facilitating local development, companies increasingly avoid methods that are overly paternalistic or assume the functions of the national or local governments. Gaining senior management's commitment to long-term social projects, which are characterised by uncertainty and complexity, is made easier if projects are shown to benefit the site's strategic goals. Case study research on large global mining companies, including interviews with social investment decision makers, has assisted in developing a Social Investment Decision Analysis Tool (SIDAT), a decision model for evaluating social projects. Multi-criteria decision analysis techniques integrating business planning processes with social impact assessment have proved useful in assisting mining companies think beyond seeking reputational benefits, to how they can meet their business goals and contribute to sustainable development.     

M3法测定土壤有效态Cd、Cr、Pb和Ni

通过M3法对耕地土壤重金属的联合测定,为土壤重金属污染监测应用提供快速联合测定的方法。用M3法测定北方耕地土壤的有效Cd、Cr、Pb和Ni,通过对M3法与其他方法进行有效重金属测定值差异性及其相关性比较,与全量的浸出率分析等探讨M3法对耕地土壤有效重金属测定的特征。结果表明,M3法在《土壤环境质量标准》(GB 15618—1995)的土壤重金属含量范围内可以测定土壤有效态重金属Cd、Cr、Pb和Ni,且呈线性极显著相关。M3法与其他方法有效Cd、Cr、Pb和Ni有较好的相关性,与DTPA法呈极显著相关;与NaNO₃法除有效Pb外,呈极显著和显著相关;与HCl法除褐土和潮土的有效Pb外,也呈极显著和显著相关。M3法的有效态Cd、Cr、Pb和Ni的测定值均为最大。M3法对4种耕地土壤有效Cd、Cr、Pb和Ni的浸出率,因土壤类型不同,有效重金属含量所占比率不同,但利用M3法测定的有效态Cd、Cr、Pb和Ni的浸出率最大。     

Is corporate social responsibility possible in the mining sector? Evidence from Catalan companies

This paper examines the role and diffusion of corporate social responsibility (CSR) management, especially in relation with the adoption of other management systems, in small and medium sized companies in the surface mining industry in Catalonia (Spain). Specifically, it identifies the most salient CSR practices, procedures and metrics and the profiles of companies more prone to adopt them. To fulfill this aim, a survey has been conducted. Results show that mining companies are familiar with CSR practices, but there is not much formalization of procedures and measurement systems of CSR yet. Results show that the majority of socially responsible practices are related to environmental issues and therefore there is a relation between CSR and the application of environmental management systems. The analysis reveals that the management of CSR activities improves with the diffusion of knowledge on CSR practices. A second survey collected the opinion of professional associations in the sector. Respondents indicate that an improvement in CSR management will lead to a better global competitive position.
