For the freshmen and sophomores, the Seminar appears to be the first classroom opportunity to study scientific aspects of a changing global environment in relation to social and humanistic issues and to link these to current public policy discussions reported in the press. Class members have recommended that multidisciplinary global change instruction be made a requirement for all college... 

Not surprisingly, the acid-base balances within the Earth system almost all involve elements of high abundance, i.e., elements that have low atomic number. In many cases, the acidic molecule is an oxygen-containing oxidation product of an element. Table 16-1 lists the main acids and bases in the global environment. The sources of these acids are chemical reactions of reduced forms of the element involved. Both gas and aqueous phase reactions exist for production of acids. 

This chapter is a brief introduction to Earth s historical environmental changes, with emphasis on the recent ice-age cycles. We chose this emphasis because preservation of these environmental records is much better than for earlier times, and because the ice ages constitute drastic changes in global environment which have... 

Reference materials for radioisotopes have mainly been used for purposes relating to nuclear and radiation safety. Historically, the development of such materials first arose from the need to assess the risk to human populations caused by worldwide contamination of food and the environment as a consequence of atomic bomb testing - particularly from bombs exploded in the atmosphere. Even now, although atmospheric testing ceased many years ago, the residues from these tests still remain the main source of radionuclides such as Cs and °Sr in the global environment (though locally, other sources may be more important in some countries).
