An optimal level of dust explosion risk management: Framework and application

The current research provides guidance on the prevention and mitigation of dust explosion using a Quantitative Risk Management Framework (QRMF). Using concepts drawn from previous studies, the framework consists of three main steps: (i) a new combined safety management protocol, (ii) the use of DESC (Dust Explosion Simulation Code) and FTA (Fault Tree Analysis) to assess explosion consequences and likelihood, respectively, and (iii) application of the hierarchy of controls (inherent, engineered and procedural safety). QRMF assessment of an industrial case study showed that the original process was at high risk. DESC simulations and Probit equations determined the destructive percentages. FTAs revealed high probabilities of explosion occurrence; in addition, detailed individual and societal risks calculations were made, before and after the framework was applied. Based on the hierarchy of controls technique, the framework showed significant risk reduction to the point where the residual risk was acceptable for the process.     

Regional Research Capacity-Building in Sustainability Science: Facts,Gaps, and Futures in Northeast Asia

Abstract

Evidence shows that some conceptual ideas relevant to both local and global sustainability have been adopted in some official documents in northeast Asian nations, particularly China, South Korea, and Japan. This seems to be a very positive signal for the future development of sustainability science in this region. However, studyes show that there are still some major gaps there. One is the problem of how to build up the regional research capacity of sustainability science among northeast Asian research institutes across different disciplines as well as different political systems. Another is how to shift the conceptual frameworks of sustainability science into the operational policy frameworks. There are four major obstacles to the enhancement of regional research capacity-building in sustainability science. In order to build up the regional research capacity in sustainability science and to realize both local and global goals of the sustainable development in northeast Asia, this paper proposes some basic frameworks, including regional institutional innovations, establishment of a regional sustainability information network, initiatives of the regional assessment programme, and focus on the regional education and training of sustainability knowledge.

中国第二次北极科学考察沿线气溶胶可溶性离子分布特征和来源

对2003年7月15～9月28日间中国第二次北极科学考察沿线所采集的气溶胶样品进行分析,获得了Na 、NH4 、K 、Mg2 、Ca2 、Cl-、MSA、SO2-4、NO3-、C2O2-4和CH3COO-11种离子的浓度.离子组成表明,气溶胶主要以海盐颗粒为主,其中(Na Cl-)的贡献平均为60.2%;其次为硫酸盐.根据因子分析,11种离子归为4个因子,解释方差为83.7%.因子1包括Na 、nss-Mg2 、nss-Ca2 、Cl-和nss-SO2-4,代表陆地和海洋混合源,解释方差为41.2%;因子2包括NH 4、nss-K 和NO3-,来源于化石燃料燃烧和生物质燃烧所释放的二次污染物,解释方差为18.9%;因子3只有MSA,来源于海洋表层浮游植物排放的二甲基硫(DMS)的氧化,解释方差为11.9%;因子4包括CH3COO-和C2O2-4,主要来源于高纬度的北温带北部森林大火,解释方差为11.6%.     

Development of inherent safety and health index for formulated product design

The numerous formulated products which are introduced to the market consist of chemical ingredients that may cause various safety and health hazards to the consumers. Therefore, it is extremely important to practice a systematic methodology to formulate products with acceptable safety and health performances. This work presents an index-based methodology to assess the safety and health hazards of the ingredients during the early formulation stage of product design. Hence, new inherent safety and health sub-indexes are introduced to improve the current safety and health hazards that are needed in formulated product design. The inherent safety and health sub-indexes are assigned with scores based on the degree of potential hazards. A higher score indicates a higher safety risk or severe health effect, and vice versa. The proposed methodology will greatly assist the users to identify the adverse safety and health effects caused by the ingredients. Hence, it is pivotal to eliminate or reduce the safety and health impacts from product usage. A case study on common ingredients used in the formulation of paint is presented on this study to describe the proposed method.
