Some deaths of cormorants in the field in Holland were attributed to PCB poisoning on more substantial evidence than was available in the foregoing incident (Koeman 1972 Walker 1990a). Birds found dead had mean liver and brain levels of 319 and 190 ppm, respectively, which are not very different from those found in experimentally poisoned individuals.

Gas-phase ion chemistry is a broad field which has many applications and which encompasses various branches of chemistry and physics. An application that draws together many of these branches is the synthesis of molecules in interstellar clouds (Herbst). This was part of the motivation for studies on the neutralization of ions by electrons (Johnsen and Mitchell) and on isomerization in ion-neutral associations (Adams and Fisher). The results of investigations of particular aspects of ion dynamics are presented in these association studies, in studies of the intermediates of binary ion-molecule Sn2 reactions (Hase, Wang, and Peslherbe), and in those of excited states of ions and their associated neutrals (Richard, Lu, Walker, and Weisshaar). Solvation in ion-molecule reactions is discussed (Castleman) and extended to include multiply charged ions by the application of electrospray techniques (Klassen, Ho, Blades, and Kebarle). These studies also provide a wealth of information on reaction thermodynamics which is critical in determining reaction spontaneity and availability of reaction channels. More focused studies relating to the ionization process and its nature are presented in the final chapter (Harland and Vallance). 

The GCS shows a great deal of potential as a tool for visualization. Wong and Cartwright have investigated the use of GCS to help in the visualization of large high-dimensionality datasets,2 and Walker and co-workers have used the method to analyze biomedical data.3 Applications in the field are starting to increase in number, but at present the potential of the method far exceeds its use.

By covering topics from individnal molecnles to systemic diseases, from fundamental concepts to advanced technologies, this book intends to provide a practical, state-of-the-art, and integrative view of the application of pharmacogenomics in drug discovery and development. I wonld like to thank aU of the anthors for their contribntions to this exciting new field. I also thank the series editor, Dr. John Walker, for his help with the editing. 

The half-lives for simazine in soil incubated in the laboratory under aerobic conditions ranged from 27 to 231 d (Beynon et al, 1972 Walker, 1976, 1976a Zimdahl et al., 1970). In field soils, the disappearance half-lives were lower and ranged from 11 to 91 d (Clay, 1973 Joshi and Datta, 1975 Marriage et al, 1975 Roadhouse and Birk, 1961).

Spodumen is a monoclinic pyroxene, space group C C2 c), with two not equivalent metal cation sites Ml and M2. The aluminum occupies the smaller Ml site, which is approximately octahedral (actual symmetry C2) with an average metal-oxygen distance of 1.92 A. The M2 site, occupied by Li, is also six-fold coordinated with an average metal-oxygen distance of 2.23 A. Both A1 and Li sites may be substitutionally replaced by ions of the transitional metals in various proportions. Both Mn " " and Cr " centers have been identified in luminescence spectra by steady-state spectroscopy (Tarashchan 1978 Walker et al. 1997). At room and lower temperatures only one emission band of Mn + occurs and the excitation spectra taken for the different wavelengths of the luminescence bands are always the same. So it is very probable that Mn + ions in the spodumen matrix present only in one site. The calculated values of 10D,j and B are consistent with the occupation of larger M2(Li) weak-field site. Mn + is mainly in Li-sites rather than Al-sites. 

Especially, we asked each author to describe the method by which they arrived at their discoveries with consideration of the reader s merits. We hope that these methodological processes might lead readers to conduct further experiments on their own. Most of the authors were selected from among the participants to the International Symposium on Advanced Functional Genomics (October II-I2, 2007, Kazusa, Japan). We thank all authors for sharing their invaluable expertise in each specific field. We also acknowledge the invaluable editorial expertise of Dr. John M. Walker.
