Science Policy Interface

This paper discusses key issues in the science–policy interface. It stresses the importance of linking the conservation and sustainable use of biodiversity to the Millennium Development Goals and to issues of immediate concern to policy-makers such as the economy, security and human health. It briefly discusses the process of decision-making and how the scientific and policy communities have successfully worked together on global environmental issues such as stratospheric ozone depletion and climate change, and the critical role of international assessments in providing the scientific basis for informed policy at the national and international level. The paper also discusses the drivers of global environmental change, the importance of constructing plausible futures, indicators of change, the biodiversity 2010 target and how environmental issues such as loss of biodiversity, stratospheric ozone depletion, land degradation, water pollution and climate change cannot be addressed in isolation because they are strongly interconnected and there are synergies and trade-offs among the policies, practices and technologies that are used to address these issues individually.

In this paper British politicians' understanding of, and attitudes towards, an important element of global environmental change are analysed through study of the parliamentary record Hansard, especially questions to ministers. In particular, attention is given to the evolution of debates concerning stratospheric ozone depletion during the period 1970–92, This focus reflects the importance of ozone depiction as an issue per se, but is also consistent with the wider argument that we need to study the development of specific environmental issues if we are to develop a more sophisticated understanding of the greening of politics; a process hitherto frequently considered as a somewhat incoherent whole, The aim is to trace the chronology of concern about stratospheric ozone, to identify the stimuli to interest in the issue, and to analyse the content and limitations of discussion. This last involves examination of interaction between a global environmental issue and the ideologies of the British national party-political system. The value of consideration of national debate about global issues is thus asserted, National and international debate and diplomacy form interacting elements of a ‘two-level game’ through which politics and environmental concerns become engaged. Previous studies which were focused chiefly on the evolution of a new environmental diplomacy at the international level thus tell only part of the story.

Entropy Of Adsorption

Of the major replacements for chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs) are now accepted as being prime contributors to stratospheric ozone depletion. As a consequence, the development of adsorbents capable of adsorbing and recovering specific HCFCs has received great attention. This paper describes an investigation of the adsorption equilibrium of 1, 1-dichloro-1-fluoroethane (HCFC-141b) vapour on a commercial hydrophobic zeolite. The corresponding Henry, Freundlich and Dubinin–Radushkevich (D–R) equilibrium isotherms have been determined and found to correlate well with the experimental data. Based on the Henry adsorption isotherms obtained at 283, 303 and 313 K. thermodynamic properties such as the enthalpy, free energy and entropy of adsorption have been computed for the adsorption of HCFC-141b vapour on the adsorbent. The results obtained could be useful in the application of HCFC adsorption on the hydrophobic zeolite studied.
