星云湖、杞麓湖磷污染来源比较

通过对星云湖、杞麓湖水体磷含量变化情况、流域产业结构和磷入湖途径的比较分析,认为近年来星云湖水体磷含量水平的大幅提高,使星云湖水质由Ⅲ类在大约5a的时间里下降为V类、劣V类,与星云湖流域及周边磷化工产业的快速发展息息相关。而杞麓湖由于流域内无磷矿资源也没有大的磷化工产业,其磷含量水平得于稳定。

PRIMA: a Dutch initiative for environmental improvement of retail assortments

Cleaner production (CP) working methods should facilitate the search for feasible CP options and contribute to their on-going implementation in a company. Over the past decade, numerous working methods have been developed in order to cater for specific segments of industry. This paper describes, compares and analyses the core components of six Dutch working methods to develop a framework for CP methodologies, to draft guidelines for the selection of an appropriate working method for a certain industry, and to identify areas which require additional methodology development. A division is proposed between four types of CP working methods: indicators, scan, pre-assessment and assessment. Each of these has its strengths and weaknesses, which calls for a careful selection of the working method, which in turn could be based on size of the company, material- and energy-intensity of the production, and complexity of the production processes. This comparative evaluation further proves that the working methods are still weak in stimulating the corporate transition process from ‘end-ofpipe’ to CP thinking and acting. It is tentatively concluded that an ‘assessment’ is superior in identifying comparatively radical environmental improvements (‘innovations’) as well as in fostering the integration of CP into the daily operation and management of a company. The use of simplified working methods in selected industries, is, however, justified given their ability to contribute to the implementation of relatively obvious CP options.

化工类建设项目布局选址的思考

化工行业是一个环境风险比较大的行业,由于化工企业经营内容、生产工艺、使用的原材料不同,潜在的环境风险也有很大的差异.为了区别对待合理选址,对化工类项目可能产生的环境风险后果进行环境风险评价与分类,再结合周围环境对环境风险的承载能力进行综合分析,根据环境优先的原则,可以合理的确定化工类项目的选址.     

Underestimated contribution of fugitive emission to VOCs in pharmaceutical industry based on pollution characteristics, odorous activity and health risk assessment

Fugitive emission has been becoming an important source of volatile organic compounds (VOCs) in pharmaceutical industry, but the exact contribution of fugitive emission remains incompletely understood. In present study, pollution characteristics, odorous activity and health risk of stack and fugitive emissions of VOCs from four functional units (e.g., workshop, sewage treatment station, raw material storage and hazardous waste storage) of three representative pharmaceutical factories were investigated. Workshop was the dominant contributor to VOCs of fugitive emission in comparison with other functional units. Extreme high concentration of VOCs from fugitive emission in unsealed workshop (94.87 mg/m³) was observed relative to sealed one (1.18 mg/m³), accounting for 31% and 5% of total VOCs, respectively. Fugitive emission of VOCs in the unsealed workshop mainly consisted of n-hexane, 1-hexene and dichloromethane. Odorous activity indexes and non-cancer hazard ratios of these VOCs from fugitive emission in the unsealed workshop were as high as that from stack exhaust. Furthermore, cancer risk of dichloromethane from fugitive emission and stack exhaust was up to (1.6-1.8) × 10⁻⁵. Odorous activity or health risk index of the VOCs from fugitive emission was up to 13 or 11 times of the corresponding threshold value, posing remarkable health threat on pharmaceutical workers. Our findings highlighted the possibly underestimated contribution of fugitive emission on VOCs in the pharmaceutical industry.     

我国建筑业推行循环经济之法律探析

建筑节能节水节地节材是按照循环经济的3R原则,实现环境保护工作的“三个转变“、建设节约型社会的必然要求.但目前我国在这一领域的还处于发展初期,其立法尤为薄弱,主要存在的问题是:一、可持续发展思想和循环经济理念未得到充分体现;二、环境影响评价制度难以推动循环经济的发展;三、相关标准体系不健全,浪费水、能、地、材的法律责任不明确;四、建筑业资源再生利用制度不健全.文章阐述了循环经济的内涵,并就我国建筑业循环经济发展中的法律障碍提出了初步的完善对策.
