The public needs to be literate in chemistry both to understand thesurrounding world and to be able to be actively involved in democratic processes. Thispaper concerns the public understanding of chemicals and chemical risk information.Preschool teachers and teacher students, representing the general public, have beenasked about e.g. what they mean with "chemicals", how they think chemicals areabsorbed into the body and their view of the difference between natural and syntheticsubstances. Furthermore, their knowledge about some chemical substances – e.g.antioxidants and dioxins – have been investigated, and also their understanding ofsome different kinds of chemical risk information. For most of the informants"chemical" is synonymous to something synthetic, artificial, unnatural, toxic,dangerous and harmful. There seems to be a contradiction between the natural on theone hand and the toxic and chemical on the other hand. The common statement "thenatural is always best" is problematized in the paper.

Review of proposals, including various draft treaties, to ban chemical weapons, 1969 to the present.

The combination of the two terms "ecology" and "chemistry" has recently come into being for researchers, biologists and chemists working at the interface of biology and chemistry. Chemical ecology is now a full research field in itself. Most living species communicate with each other through molecules and chemical signals called mediators. The chemical language, using chemical mediators instead of words, is a universal language in nature, and appears indispensable to the maintenance of terrestrial and aquatic ecosystems. Chemical communication is by far the most used means of communication in the living world. Trying to understand the language of nature, ecologists and chemists are faced with the complexity and creativity of organisms. This book presents the most advanced and varied aspects of this growing discipline. It provides, compared to other available books which mostly deal with relatively simple systems, dual or tritrophic relationships around a small number of model organisms and chemical mediators, a holistic view of chemical ecology
