Food Chain Bioaccumulation. Data are available that indicate that chloroform does not bioconcentrate in aquatic organisms (Barrows et al. 1980 Veith et al. 1980) however, data are lacking for plants and other animals (e.g., vacuolar plants, shellfish, or macroinvertebrates) as well as for the biomagnification potential of chloroform in terrestrial and aquatic food chains. Additional information on bioconcentration and biomagnification could be useful in establishing the significance of food chain bioaccumulation as a route of human exposure. 

Fillers. The buffering action of an alkaline filler is necessary to ensure permanence in filled paper. Retained alkalinity in the paper as it ages would resist any drop in pH that might result from absorption of either carbon dioxide or sulfur dioxide from the air. Acidic fillers, such as certain types of clay, accelerate the aging process. Calcium carbonate is an ideal filling material for permanent paper as well as for some grades not requiring permanency. In fact, the work of Barrow made the use of calcium carbonate a requirement in the manufacture of permanent book papers (1). 

The detrimental effect of acid in paper has been well documented (1, 2, 3, 4), and numerous treatments have been proposed to alleviate the effect. Schierholz (5), Barrow (6), and others have proposed methods of neutralizing the acids in paper based on aqueous treatments. However, many papers are sensitive to aqueous treatments, either because of the fragility of the paper or the tendency of the inks or colors to run when exposed to water, and for these papers a nonaqueous deacidification treatment is required. 

S) can be obtained from thioethers and mercaptans, the heats of formation of some of which have recently been collected by Barrow and Pitzer i these are chiefly old values, probably not accurate to better than 3 kcal. Combining these results with (C-H), (C-G), and (S-H) we obtain (C S)=59 kcal. This fits the results fairly well. Pauling s s value, converted to our heats of atomization, is 58 kcal.

Much of the spectroscopic work involving V0(g) has been reviewed and referenced by Rosen (1 ) and Weltner (J ). The adopted vibrational and rotational constants as well as the electronic levels are those tabulated by Rosen (10). The EPR work of Kasai (12) and the optical absorption study by Richards and Barrow (j ) established that the ground state was s". As reported in Rosen (10) there is evidence from matrix studies Indicating a transition at 23890 cm". We assume this level has a quantum weight of 4. 

Specific adsorption on well defined materials has been the subject of many reviews [8-13]. Specific adsorption plays a key role in transport of nutrients and contaminants in the natural environment, and many studies with natural, complex, and ill defined materials have been carried out. Specific adsorption of ions by soils and other materials was reviewed by Barrow [14,15]. The components of complex mineral assemblies can differ in specific surface area and in affinity to certain solutes by many orders of magnitude. For example, in soils and rocks, (hydr)oxides of Fe(IH) and Mn(IV) are the main scavengers of metal cations and certain anions, even when their concentration expressed as mass fraction is very low. Traces of Ti02 present as impurities are responsible for the enhanced uptake of U by some natural kaolinites. In general, complex materials whose chemical composition seems very similar can substantially differ in their sorption properties due to different nature and concentration of impurities , which are dispersed in a relatively inert matrix, and which play a crucial role in the sorption process. In this respect the significance of parameters characterizing overall sorption properties of complex materials is limited. On the other hand the assessment of the contributions of particular components of a complex material to the overall sorption properties would be very tedious. 

Barrow reports common intersection points of uptake (pH) curves obtained for sorption of phosphates (constant total concentration) by soils at different NaCl concentrations [25]. The slope of these curves decreases when the ionic strength increases, and the uptake of phosphates from 1 mol dm NaCl is almost independent of pH. The position of these intersection points on the pH scale is a function of the initial phosphate concentration. Similar effect was reported for selenates (IV). Interestingly for borates [26] whose uptake increased with pH over the pH range of interest, a common intersection point (pH of zero salt effect) was also observed but in this case the slope was higher for higher ionic strengths. This type of behavior has not been reported for well defined adsorbents,... 

This is one of the most important variables to study, and temperature effects in soil kinetic studies have been frequently reported (e.g., Barrow and Shaw, 1975 Evans and Jurinak, 1976 Sparks and Jardine, 1981 Ogwada mid Sparks, 1986a). Rate coefficients for elementary chemical reactions follow a temperature dependence that can be described by the well-known Arrhenius equation... 

In 1913, long after Charles Darwin had argued for the htness of organisms for their environment, the Harvard chemist Lawrence J. Henderson pointed out that the organisms would not exist at all except for the htness of the environment itself. Fitness there must be, in environment as well as in organism, he declared near the outset of his classic work. The Fitness of the Environment (1913, p. 6). While most of Henderson s contemporaries ignored the philosophical implications of this work, as John Barrow and Frank Tipler have noted, it still comprises the foundahon of the Anthropic Principle as applied to biochemical systems (1986, p. 143). 

John D. Barrow is Professor of Mathematical Sciences in the Department of Applied Mathematics and Theoretical Physics at the University of Cambridge and Director of the Millennium Mathematics Project. He is the author of The Artful Universe Expanded (Oxford University Press, 2005) and The Infinite Book A Short Guide to the Boundless, Timeless and Endless (Cape, 2005), as well as co-editor of Science and Ultimate Reality Quantum Theory, Cosmology and Complexity (Cambridge University Press, 2004).
