Review of present European environmental policies and legislation involving cultural heritage

Cultural heritage is being addressed by a number of charters and conventions and it is clear that its consideration within decision-making processes is progressively becoming a real challenge, both for developers and public authorities. Against this background, this paper reviews the environmental assessment framework developed by the European Community, as this should increasingly influence decision making about cultural heritage in an urban setting. The legislative framework for access to environmental information is also reviewed because of its relevance to the decision-making process.The Directives on Environmental Impact Assessment and Strategic Environmental Assessment both require a consideration of cultural heritage in decision making. This requirement can go some way to addressing the paradox in the European Community's position whereby the community wishes to conserve and enhance its own cultural identity whilst, at the same time, cultural heritage is usually defined at a local level. The present paper suggests that, given their flexibility, the two European Community directives on environmental assessment constitute a promising opportunity to address this seeming paradox, but that there is a significant gap between legal obligations and the methodological tools to meet them.

生态系统服务功能及其价值核算

生态系统服务功能是指生态系统服务与生态系统功能的综合，指生态系统与生态过程所形成及所维持的人类赖以生存的自然环境条件与效用，生态系统服务功能对于人类生存发展具有重要的价值，应该在社会经济体系中得以体现，本文探讨了生态系统服务功能的类型，价值核算方法与理论及其应用研究在完善国民经济核算体系、促进可持续发展等方面的重要意义，并对今后发展进行了展望。     

企业需要建立人性化的安全管理

由于我国对企业特别是海外来大陆投资的企业，缺乏严格的安全管理手段，致使不少企业屡次出现安全事故。为了减少企业安全事故的发生，提高企业安全度，要求企业在贯彻“安全第一，预防为主”的基本方针的基础上。建立“以人为本。以制度和伦理道德为约束的人性化的安全管理系统”。本文给出了该系统的模型，并对此模型进行了分析和解释，探讨了相关的几个理论基础，最后给出了人性化安全管理的实质。通过该系统的管理执行，使企业在尊重人权、尊重生命的前提下发展壮大，最终实现安全的全球化。     

SUSTAINABILITY AT THE LOCAL LEVEL: MANAGEMENT TOOLS AND MUNICIPAL TAX INCENTIVE MODEL

The implementation of sustainable development may seem a simple concept when written on paper. However to carry-out long term actions put forward by the Agenda 21 (AG21) at the local level represents one of the main challenges as municipal governments in general do not have the capacity to effectively implement the process. Regional environmental assessment (REA) has shown to be effective in supporting decision-making not only to correct environmental problems due to past unsustainable social-economic developments but also help local governments to implement sustainable actions. However this requires long-term investments of AG21 plans and projects. The allocation of regular and consistent financial resources is one of the main ingredients for the sustainable development process. But traditional plans and projects financed by national and/or international funds may not be sustainable in the long-term because they become dependent on external funding. Research demonstrate that innovative economic instruments such as ecotaxes represent a feasible alternative to sponsor local sustainability because taxes are collected permanently by the government and could be invested in continuous actions. Ecotaxes experiences have provided important reference to structure a municipal incentive model (MIM) to sponsor AG21’s environmental plans and projects on a long-term (permanent) basis. However sustainable development cannot be solely through economic investments. A comprehensive municipal environmental management scheme (MEMS) has been established to support the incentive model. The scheme seeks not only to improve local institutional framework but also incentive continuous participation of local stakeholders at all levels of society. Participatory events and the provision of incentives (educational and financial) are key to motivate society to protect the environment and support actively the sustainable development process as emphasised in the RIO-92 Conference.     

铅锌矿区玉米中重金属污染特征及健康风险评价

以西南某铅锌矿区为研究区域,测定了92份玉米样品中Pb、Zn、Cd、Cr和Ni的含量,开展了矿区玉米籽粒中重金属污染特征及健康风险研究.应用单因子污染指数和内梅罗综合污染指数分析了重金属在玉米中的污染状况,采用健康风险评价模型评价了重金属对人体健康造成的风险,同时利用主成分分析法解析了重金属的主要来源.结果表明,玉米籽粒中Pb、Zn、Cd、Cr和Ni的平均含量分别为0.30、23.75、0.21、1.33和1.15 mg ·kg^-1;除重金属Zn外,其他4种重金属均超过我国食品卫生标准限值,研究区玉米籽粒中Pb、Cd、Cr和Ni的综合污染指数范围介于4.32~9.07之间,均属于重度污染,Zn的综合污染指数小于1;重金属通过玉米籽粒摄入引起的复合重金属污染对成人和儿童均存在健康风险,且对儿童造成的健康风险高于成人.玉米籽粒中5种重金属可以由2个主成分来反映,第一主成分主要支配Pb、Cd、Cr和Ni的来源,第二主成分支配Zn的来源.玉米籽粒重金属含量与土壤重金属含量之间没有明显相关性.     

沱江沉积物中有机氯农药分布特征及其与藻类有机质的关系和生态风险评估

使用气相色谱-质谱联用仪分析了长江支流沱江流域48个表层沉积物中有机氯农药（organochlorine pesticides,OCPs）的残留水平,探讨了其分布和组成特征及其与总有机碳（total organic carbon,TOC）、藻类有机质之间的关系,以及评估其生态风险.结果表明沱江流域表层沉积物中OCPs的总含量为3.17~127 ng·g^-1,其中六六六（hexachlorocyclohexane,HCHs）类农药的含量为2.83~86.0 ng·g^-1,滴滴涕（dichlorodiphenyltrichloroethane,DDTs）类农药的含量为0.340~40.9 ng·g^-1.OCPs空间分布特点为：上游 < 中游 < 下游 < 支流.HCHs和DDTs的组成成分分析表明,沱江流域存在林丹输入的现象,主要来自于历史残留,这与绝大多数流域的DDTs的输入状况相似.OCPs含量与TOC、藻类有机质含量之间存在着极显著的正相关性关系,表明藻类有机质在TOC对沉积物中的OCPs分配中起更为重要的作用.生态风险评估表明,沱江流域表层沉积物的有机氯农药存在较大的生态风险,可能对河流的底栖生物及生态环境造成明显的影响.     

中国集成电路制造行业VOCs排放特征及控制对策

中国电子信息产业发展迅速,集成电路等电子器件产量不断增加.在集成电路制造的过程中,大量有机溶剂的使用导致VOCs的产生和排放,从而对大气环境造成影响.为掌握集成电路制造行业VOCs的排放特征,系统分析了其工艺流程和产排污环节,分析了行业废气收集和治理现状,通过对典型企业VOCs的排放监测,获得VOCs排放水平;采用排放因子法核算行业VOCs历史排放量,并基于行业排放特征及减排潜力分析,提出了相应的污染防治对策.结果表明：在集成电路制造中,VOCs排放环节主要集中在光刻、清洗、去胶等过程,1 m²集成电路产量约使用87 g有机溶剂,VOCs产生量较大;通过采取高效的VOCs治理技术,集成电路制造行业有组织排放水平较低,平均浓度为2.1 mg·m^-3,但厂界无组织排放浓度相对较高,平均浓度为0.78 mg·m^-3,接近国家标准的排放限值.根据排放量核算结果,2011—2016年中国集成电路制造行业VOCs排放量呈逐年上升的趋势,主要受产量增加而相应污染控制技术水平提升有限的影响,无组织排放量比重大,占排放总量的38.1%~45.1%.
