Environmental theme

Prosperity without pollution has become the fundamental environmental theme. Support for the new approach—the new ethic—must be broad based and includes... [Pg.48]

Water quality projects such as those described below have been shown to be effective methods for engaging students in environmental chemistry courses for majors (Juhl et al. 1997) and for nonscience majors (Lunsford et al. 2007). When the water quality research projects were conducted, Chemistry and the Environment was linked to a world geography course as part of a learning community. Poor water quality and access to potable water were a global environmental theme for both courses. Consequently, the chemistry research projects focused primarily on water analysis. Field water testing kits, atomic absorption spectroscopy, and fluorescence methods (typically for biological con-... [Pg.38]

In the mid-1990s, Carnegie Mellon University s Environmental Institute began to implement the Environment across the Curriculum initiative (75). The goal was to develop modules that contained environmental themes that could be used in courses in every college in the university... One of the modules, which focused on green chemistry and was specifically designed for the first year chemistry student, will be discussed. [Pg.82]

Another important need in the curriculum is for a far greater emphasis on design and control for process safety, waste minimization, and minimal adverse environmental impact. These themes need to be woven into the curriculum wherever possible. The AlChE Center for Chemical Process Safety is attempting to provide curricular material in this area, but a larger... [Pg.188]

The separate parts in the school chemistry textbooks are accompanied by student-exercises that mainly aim to train the students ability to reproduce the chemical knowledge presented. It takes quite a large number of chemistry lessons before a student will come to a point where the new chemical knowledge may be related to society and the everyday world. Only some students start to ask about nitrates and environmental problems while climbing the ladder. Mary never make such a coimection. According to the common ciuriculum philosophy that students first need to climb the ladder , it takes a long climb for students to see the relevance to societal themes in fact it is impossible within the (time) limits of the school chemistry curriculum. [Pg.33]

A central theme of this text is the development of biomarker assays to measure the extent of toxic effects caused by chemicals both in the field studies and for the purposes of environmental risk assessment. [Pg.300]

Symmetry breaking associated with chiral phenomena is a theme that recurs across the sciences—from the intricacies of the electroweak interaction and nuclear decay [1-3] to the environmentally influenced dimorphic chiral structures of microscopic planktonic foraminifera [4, 5], and the genetically controlled preferential coiling direction seen in the shells of snail populations [6, 7]. [Pg.268]

Export processes are often more complicated than the expression given in Equation 7, for many chemicals can escape across the air/water interface (volatilize) or, in rapidly depositing environments, be buried for indeterminate periods in deep sediment beds. Still, the majority of environmental models are simply variations on the mass-balance theme expressed by Equation 7. Some codes solve Equation 7 directly for relatively large control volumes, that is, they operate on "compartment" or "box" models of the environment. Models of aquatic systems can also be phrased in terms of continuous space, as opposed to the "compartment" approach of discrete spatial zones. In this case, the partial differential equations (which arise, for example, by taking the limit of Equation 7 as the control volume goes to zero) can be solved by finite difference or finite element numerical integration techniques. [Pg.34]

The quantum theory of the previous chapter may well appear to be of limited relevance to chemistry. As a matter of fact, nothing that pertains to either chemical reactivity or interaction has emerged. Only background material has been developed and the quantum behaviour of real chemical systems remains to be explored. If quantum theory is to elucidate chemical effects it should go beyond an analysis of atomic hydrogen. It should deal with all types of atom, molecules and ions, explain their interaction with each other and predict the course of chemical reactions as a function of environmental factors. It is not the same as providing the classical models of chemistry with a quantum-mechanical gloss a theme not without some common-sense appeal, but destined to obscure the non-classical features of molecular systems. [Pg.261]

All of the above considerations have sometimes led to a too rigid picture of the membrane structure. Of course, the mentioned types of fluctuations (protrusions, fluctuations in area per molecule, chain interdigitations) do exist and will turn out to be important. Without these, the membrane would lack any mechanism to, for example, adjust to the environmental conditions or to accommodate additives. Here we come to the central theme of this review. In order to come to predictive models for permeation in, and transport through bilayers, it is necessary to go beyond the surfactant parameter approach and the fluid mosaic model. [Pg.24]

Increasingly, guidelines resulting from political decision process of the European Union influence national markets and global competition. In order to have an influence on behalf of the interests of the plastics industry, the Association of Plastics Producing Industries, (VKE), is reported to wish to intensify its communication with European political institutions. The VKE sees the discussion about the EU book on the environmental problems relating to PVC as particularly controversial, and does not consider that it takes important points of view sufficiently into account. The treatment of the PVC theme, is examined as an example of so-called europisation of the work of associations. (Article translated from Kunststoffe 91 (2001) 4, pp.26-27). [Pg.66]

In 1969, with recognition of environmental problems emerging, the resources of the University were put to work for the benefit of the state of California. Essential characteristics of what was needed to resolve environmental problems became apparent from work addressing California s critical concern air quality. These contrasted with basic research themes. [Pg.200]
