A novel approach for VOC source apportionment combining characteristic factor and pattern recognition technology in a Chinese industrial area

Volatile organic compound (VOC) emission control and source apportionment in small-scale industrial areas have become key topics of air pollution control in China. This study proposed a novel characteristic factor and pattern recognition (CF-PR) model for VOC source apportionment based on the similarity of characteristic factors between sources and receptors. A simulation was carried out in a typical industrial area with the CF-PR model involving simulated receptor samples. Refined and accurate source profiles were constructed through in situ sampling and analysis, covering rubber, chemicals, coating, electronics, plastics, printing, incubation and medical treatment industries. Characteristic factors of n-undecane, styrene, o-xylene and propane were identified. The source apportionment simulation results indicated that the predicted contribution rate was basically consistent with the real contribution rate. Compared to traditional receptor models, this method achieves notable advantages in terms of refinement and timeliness at similar accuracy, which is more suitable for VOC source identification and apportionment in small-scale industrial areas.

A Cumulative Energy Demand indicator (CED), life cycle based,for industrial waste management decision making

Life cycle thinking is a good approach to be used for environmental decision-support, although the complexity of the Life Cycle Assessment (LCA) studies sometimes prevents their wide use. The purpose of this paper is to show how LCA methodology can be simplified to be more useful for certain applications.In order to improve waste management in Catalonia (Spain), a Cumulative Energy Demand indicator (LCA-based) has been used to obtain four mathematical models to help the government in the decision of preventing or allowing a specific waste from going out of the borders. The conceptual equations and all the subsequent developments and assumptions made to obtain the simplified models are presented.One of the four models is discussed in detail, presenting the final simplified equation to be subsequently used by the government in decision making.The resulting model has been found to be scientifically robust, simple to implement and, above all, fulfilling its purpose: the limitation of waste transport out of Catalonia unless the waste recovery operations are significantly better and justify this transport.

A quantitative water resource planning and management model for an industrial park level

This paper introduces an integrated water management model at the industrial park level. It suggests four approaches to water management: first, direct water reuse among users; second, water reuse among users by blending with freshwater; third, water reuse between users and a wastewater treatment plant; and fourth, groundwater recharge by reclaimed wastewater or other feasible applications in order to optimize the overall water efficiency. The model results in a comprehensive management methodology for optimizing water resources within an industrial park, seeking potential water reuse among industries, and incorporating the size and cost of reclaimed wastewater delivery systems. A case study is employed to test the model’s feasibility. An economic analysis of the optimized water use network is also carried out, showing the potential water and cost savings.     

乡镇工业电镀行业主要污染物排放量的估算方法

电镀分有氰电镀与无氰电镀两类。乡镇工业电镀行业的环境污染最主要是氰污染和铬污染。本文针对乡镇电镀行业的特点,调查了湖南省沅江市、四川省新都县、湖北省黄陂县、汉川县以及江苏省部分县市乡镇电镀厂,将收集资料及实际监测资料进行回归分析,得出乡镇电镀行业的污染物发生量大小与原材料的消耗有关,可以用多元回归方程估算乡镇电镀行业主要污染物发生量。这一估算方法简单易行,实用可靠,操作方便。     

环境规制的蓝色红利效应研究

利用中国工业企业数据库2004~2009年制造业企业数据,以清洁生产目录标准的政策实施为外生冲击事件,基于倍差估计法（DID）实证检验了环境规制对企业盈利能力、盈利质量、波特效应和管理创新成本等蓝色红利的影响.结果发现：环境规制显著提升了制造企业的利润率和企业的现金流充裕性,改善了企业的盈利能力和盈利质量;环境规制显著降低了企业管理创新成本,但波特效应不显著.环境规制的蓝色红利效应存在地方策略互动、企业规模和所有制的异质性：地方政府之间的策略性不合作抑制了环境规制蓝色红利效应.企业规模的扩大提高了管理创新成本,但强化其他相关的蓝色红利效应.环境规制对国有企业的利润率、现金流以及全要素生产率的改善作用强于非国有企业,但更有助于降低非国有企业的管理创新成本.     

Design training and aesthetic evaluation: An intergroup comparison

A number of studies have observed differences in the evaluation of visual, aesthetic stimuli between those with and without professional training in art and design. If exposure to design training underlies such differences it follows that evidence of training effects should be observable when comparing subjects at different stages of design training, and not observable when comparing subjects at different stages of non-design training. In addition, this evidence should be consistent with directional predictions. The study reported in this paper investigated this question using a sample of 192 trained and untrained subjects in an evaluative task. Subjects were from two departments (Design and Computer Studies) of the same educational establishment and comprised balanced groups of lecturers, 1st, 2nd and 3rd year undergraduate students. The results obtained demonstrated evaluative differences and patterns of association both within and between the subject groups consistent with a training hypothesis.
