全面落实新《安全生产法》强化焦化企业安全管理

新《安全生产法》的颁布和实施,对焦化企业提出了更高的要求。焦化企业可以通过完善安全仪表系统、开展危险与可操作分析、建立企业安全生产预警体系、贯彻执行焦化行业安全生产标准和建立现代企业安全管理制度来更好地促进其安全生产。     

石油化工企业环境风险分级评价指标体系研究

在现有研究基础上,从石化行业环境风险特点与现状着手,针对现有环境风险分级评价体系无法适应我国当前石化行业环境风险现状这一问题,对石化企业环境风险要素进行了梳理和分析.以此为基础从突发性环境风险、非突发性环境风险和选址敏感性三方面入手选取了石化企业环境风险分级评价指标,对各指标的含义及量化方法进行了分析,构建了石化企业环境风险分级评价指标体系.利用层次分析法确定体系指标权重,利用专家评分法对评价指标进行赋分,能够准确反映石化企业环境风险的实际情况.以天津滨海新区某石油化工企业为案例,验证了评价指标体系的有效性.     

Managers as drivers of CSR in state-owned enterprises

Corporate social responsibility (CSR) is increasingly required not only of private sector companies, but also of state-owned enterprises (SOEs), whose main function is to provide services to society and not principally to obtain financial reward. The important role played by managers in implementing CSR has been demonstrated by prior research. The objective of this paper is to examine how managers of SOEs perceive the concept of CSR, the reasons for their involvement and how it is integrated into everyday business practices. In addition, we examine whether managers' attitudes towards CSR policies are influenced by their personal profiles and by the sector in which the SOEs work. We find that, although these managers are aware of the importance of the CSR principles underlying their activities and understand the meaning, scope and dimensions of CSR, there remains an evident need to enhance the application of CSR policies among the strategies of SOEs. The manager profile and the sector in which the SOEs work both have a strong influence on their behaviour regarding CSR issues.     

Serious BTEX pollution in rural area of the North China Plain during winter season

Atmospheric BTEX compounds(benzene, toluene, ethylbenzene and xylenes) in a rural site of the North China Plain(NCP) were preliminarily investigated in winter, and the outdoor concentrations(25.8–236.0 μg/m3) were found to be much higher than those reported in urban regions. The pollution of BTEX inside a farmer's house was even more serious, with combined concentrations of 254.5–1552.9 μg/m3. Based on the ratio of benzene to toluene(1.17 ± 0.34) measured, the serious BTEX pollution in the rural site was mainly ascribed to domestic coal combustion for heating during the winter season. With the enhancement of farmers' incomes in recent years, coal consumption by farmers in the NCP is rapidly increasing to keep their houses warm, and hence the serious air pollution in rural areas of the NCP during winter, including BTEX, should be paid great attention.     

江苏省太湖流域农村生活污水处理技术评价

农村生活污水处理技术种类繁多,实际应用效果参差不齐,且各类技术缺乏对实际工程实施的指导。针对江苏省太湖流域农村生活污水排放特点,研究了毛细管渗滤沟处理技术、厌氧池-人工湿地组合工艺、厌氧滤池-氧化塘-生态渠技术、SBR-化学除磷和膜生物反应器等技术的工艺参数、处理效果、投资估算和操作管理要求,并对各项技术进行综合评估。针对不同的污水处理规模,总结不同地区相应的推荐处理技术。     

太阳能驱动的一体化设备在农村污水处理中的应用

以太湖流域环境敏感区内某村为例,介绍了太阳能驱动的污水处理一体化设备对农村生活污水处理的应用。连续6个月的运行及监测数据表明,污水处理实际消耗电量与光伏发电量比值为54.3%,能够有效地保证污水处理所需动力。污水处理部分采用A/O-BF一体化技术,生活污水经处理以后,出水水质达到GB 18918-2002《城镇污水处理厂污染物排放标准》中一级A标准。太阳能驱动的污水处理一体化设备运行稳定、故障率低、无需投加药剂且无运行费用,适宜在太湖流域的农村地区推广应用。     

Uneven Environmental Management: A Canadian Perspective

Advocates of community-based approaches to environmental management argue that by respecting local circumstances, skills, and concerns we may improve the prospects of achieving environmental sustainability; yet, within nation states such as Canada, environmental conditions, management and enforcement costs and capabilities, and power differentials within and among civic and public sectors may result in a highly differentiated capacity for environmental management across different localities and regions. This article draws on insights of political ecology to 1) create a conceptual framework that identifies key elements shaping regional environmental management regimes and to 2) undertake a comparative analysis to assess how elements interact to generate uneven management outcomes. I compare experiences of two Canadian biosphere reserves designated in 2000: Clayoquot Sound, BC; and Redberry Lake, SK. Analysis reveals that differences in governance and institutional capacities in the biosphere reserves are key to explaining uneven local outcomes. Where the public and civic sectors are strong, a robust and publicly vetted form of management will emerge. Where these sectors are weak and land is held as private property, environmental nongovernmental organizations can set the type and level of management, to the exclusion of effective civic and state involvement. This result may improve environmental sustainability but hinder social sustainability of a management regime and raises questions about the efficacy of community-based management.     

江苏省新农村建设评价指标体系初探——以大丰市南阳镇为例

党的十六届五中全会提出了新农村建设的任务,江苏省也于近期举办了新农村建设专题研讨会。本文通过对现存相关指标体系的回顾分析,结合新农村建设“生产发展、生活宽裕、乡风文明、村容整洁、管理民主”的内涵,对江苏省新农村建设指标体系进行了初步探讨,并采用这一体系对大丰市南阳镇新农村建设实现程度进行了评价。结果表明,虽然江苏省农村发展水平已有明显提高,但仍需要进一步加强农村工作,努力达到新农村建设的目标。
