Book Description
This volume is a collection of papers produced within the framework of the Italian National Antarctic Research Programme (PNRA) on the monitoring and control of environmental contamination. The volume represents a contribution of the PNRA to the study of planetary contamination and to the understanding of the processes of global change. The research focuses on the measurement and analysis of trace elements and organic micropollutants in the following matrices: snow/firn, seawater, soils, sediments, suspended particulate matter, pack ice, atmosphere, and biota. The results presented extend beyond the development of specific analytical methodologies, to explicitly tackle significant environmental issues concerning global changes. Particularly relevant are the results concerning time changes of CFCs in the troposphere and lead concentration in Antarctic snow in Victoria Land, the presence of organic micropollutants in various Antarctica matrices, and the seasonal evolution of trace elements and

Book Description
This thought-provoking and ambitious volume surveys the causes and extent of environmental contamination in Antarctica, and looks critically at future prospects. It highlights the key role that modern techniques of analytical chemistry play in achieving reliable empirical data in this field and their impact on shaping legal provisions. Written by prominent scientists and experts in Antarctic sciences, this work gives an overview of the studies undertaken by countries to assess the impact of pollution phenomena on the uniquely clean environment of Antarctica. Empirical studies and regulatory issues are evaluated in context with the goal of providing a model approach to more polluted areas of the world.

Book Description
Polar ice cores have provided tremendous advances in our knowledge of past climate change. They also contain an archive of geochemical data, which can certainly delineate some of the forcing factors that govern climate change. However, our ability to interpret these data is severely curtailed by lack of knowledge of the processes governing the transfer of chemical species from the air to the snow. This book outlines the potential and problems of ice core chemistry and discusses the processes involved in air-snow transfer. It gives the state of current knowledge and an agenda for future research.

Book Description
Ice and snow on Earth modulate and modify the climate, chemistry and fate of air and water pollutants. Climate change is drastically impacting Nature and extent of the cryosphere, with attendant feedbacks on atmospheric composition and climate. These changes are happening at a rate that outpaces the development of fundamental knowledge of processes that occur within/on the surfaces of ice and snow, confounding our ability to develop a predictive capability for future states of the Earth environment.This set, comprising 17 chapters, written by world experts on these topics, are thus intended to document the current state of understanding of the structure, physical properties, abundance, and chemical and microbiological processes that occur within/on ice and snow in all Earth environments in which it exists, and to express needs for improvement of that understanding. This, only comprehensive treatise/collection that covers environmentally relevant chemistry and related physical aspects of snow and ice in the Earth system, and the connections to climate change, will be accessible to those with introductory college-level understanding of chemistry and physics.

Book Description
The Arctic troposphere (0 to ca. 8 km) plays an important role in environmental concerns for global change. It is a unique chemical reactor influenced by human activity and the Arctic ocean. It is surrounded by industrialized continents that in winter contribute gaseous and particulate pollution (Arctic haze). It is underlain by the flat Arctic ocean from which it is separated by a crack-ridden ice membrane 3 to 4 m thick. Ocean to atmosphere exchange of heat, water vapor and marine biogenic gases influence the composition of the reactor. From September 21 to December 21 to March 21, the region north of the Arctic circle goes from a completely sunlit situation to a completely dark one and then back to light. At the same time the lower troposphere is stably stratified. This hinders vertical mixing. During this light period, surface temperature reaches as low as -40°C. In this environment, chemical reactions involving sunlight are generally much slower than further south. Thus, the abundance of photochemically reactive compounds in the atmosphere can be high prior to polar sunrise. Between complete dark in February and complete light in April, a number of chemical changes in the lower troposphere take place.
