化学品安全知识与应急科普宣传研究

Based on the theme of "chemical awareness and safety accident response capability", this paper conducts a questionnaire survey for college students. In response to the survey results, scientific, popular, and novel offline activities/online publicity will be used to popularize chemical basics, relevant laws and regulations, and chemical safety accident emergency response methods for university students. The aim is to improve the level of understanding of various types of chemicals among college students. In the event of sudden chemical safety incidents, corrective measures can be taken, and useful information can be accurately identified after a chemical accident.     

Chemical safety in a vulnerable world

The title of this article is the motto of the fourth meeting of the Intergovernmental Forum on Chemical Safety (Forum IV), which is to be held in Bangkok in November 2003. The IFCS has been in existence for 10 years. During this period politicians, scientists, and the general public have become increasingly aware of the risks associated with chemicals. International conventions providing for prohibitions and restrictions of dangerous chemicals, and for better control of trade have been set up. These conventions will soon be binding under international law. In developing countries many people who handle or use hazardous chemicals are illiterate or poorly educated; they may not fully understand what they are handling. The industrialized countries therefore have a special duty to incorporate chemical safety in development cooperation measures. Through their presence at this year's forum, prominent chemists such as Carl Djerassi will seek to underline the fact that a long term preventive approach to healthcare and the environment is only possible through international cooperation. This overview describes current developments in the field of chemical safety policy and presents a selection of the legislation currently in force for chemicals in the European Union. It also provides an insight into the interwoven structure of international cooperation that takes place at both the political and the technical level.     

Micellen als chemische Nano‐Laboratorien

Loaded nanomicellar structures in water with potentional application in cosmetics such as sun protection and care of sunburn were developed on establishing chemical experiments for teaching without requiring hazardous chemicals, however, concerning an actual field of research. Such micellar systems in water may form „nano laboratories“, for example for the application of lipophilic substances in water. This is demonstrated for fluorescent dyes and lipophilic pH indicators. Finally, supramolecular functional units were stabilized in such structures inducing their operation by interaction. Such micelles may be variously applied in chemical didactics beginning from tests for demonstration, and moreover, for basic and advanced chemical education of students.     

The effect of sodiumlignosulphonate on cement properties for conditioning the hazardous wastes

Sodiumlignosulphonate was added to sulphate resisting cement as chemical additive to modify its physical and chemical properties for conditioning hazardous and radioactive wastes for long term disposal. The effect of some organic and inorganic chemicals on sulphate resisting cement was investigated. The physical properties such as density, porosity percent and absorption percent for all the studied samples as well as the compressive strength values and the leaching properties were also determined. The thermal stability and the radiation stability were also investigated.     

Brominated flame retardants in the European chemicals policy of REACH-Regulation and determination in materials

The EU REACH legislation will require the registration of 30,000 currently marketed chemicals, including the main commercial BFRs in use (Deca-BDE, HBCD and TBBP-A). Much of the data needed for registration are already available, thanks to risk assessments of continued production and use already undertaken in the EU. Within the authorisation, substitution by less hazardous chemicals is encouraged. Both qualitative and quantitative methods for the analysis of flame-retarded polymers are needed in order that the identity and concentration of the BFRs can be established and compliance with regulations including the RoHS Directive demonstrated. These are reviewed.     

介绍一个典型的安全教育实验

安全教育在高校实验教学中占有重要地位,国内很多高校开设了形式多样的安全教育课程,但多以文字形式为主,对学生而言相对枯燥,记忆不深刻,效果有限。为有效提高学生安全防范意识和能力,我们结合化学安全教育的特点,利用已有的物理化学实验,设计了一个立体化的典型安全教育实验,使之能适用于广泛的用途。     

Using polymeric hydroxypropyl methylcellulose as an alternative to ‘micellar catalysis’ to enable chemical reactions in water

Synthetic chemistry relies heavily on organic solvents which are often toxic and hazardous as well as expensive in purchase and disposal. The application of water as an alternative reaction medium is not only advantageous from an environmental and safety perspective but can also offer improved selectivity and reaction rates. The exploration of this new, sustainable approach comes along with an ever-growing spectrum of reaction procedures. In this current opinion, we provide an overview of a new methodology that uses a polymeric cellulose derivative, hydroxypropyl methylcellulose, to enable chemical reactions in water.
