The first consideration was the speciation and distribution of the metal in the sediment and water. Benthic organisms are exposed to surface water, pore water and sediment via the epidermis and/or the alimentary tract. Common binding sites for the metals in the sediment are iron and manganese oxides, clays, silica often with a coating of organic carbon that usually accounts for ca. 2% w/w. In a reducing environment contaminant metals will be precipitated as their sulfides. There is not necessarily a direct relationship between bioavailability and bioaccumulation, as digestion affects the availability and transport of the metals in animals, in ways that differ from those in plants.

Elemental carbon concentrations are the result of incomplete combustion. These primary carbon particles should closely track the gas phase products of combustion processes. Figures 6 and 7 show that this is indeed the case. Figure 6 presents the relationship between 1-hour average samples of elemental carbon and total oxides of nitrogen. Figure 7 shows the relationship between elemental carbon and CO. One reason for the scatter in the CO results is that the data are only reported to the nearest ppm. 

The Baeyer-Villiger oxidation of 3-trimethylsilylcyclohexanone [250] is regioselec-tive as indicated. The reason for the selectivity is electronic which is revealed by an examination of the relationship between the polar groups of the ketone. Here we find a disjoint sequence, the a and f) carbon atoms are both quasidonors as dictated by their respective neighbors. The observed rearrangement, but not the alternative mode, relieves the unfavorable electronic interactions. 

Relationship between Energy Release and the Oxidation State of Carbon A eukaryotic cell can use glucose (C6Hi206) and hexanoic acid (C6H1402) as fuels for cellular respiration. On the basis of their structural formulas, which substance releases more energy per gram on complete combustion to C02 and H20 ... 

In 1947, Kinney (15) drew attention to a direct relationship between the amount of acetic acid formed on oxidizing coal with nitric acid and potassium dichromate and the yields of methane obtained by low temperature carbonization. The oxidation method leading to acetic acid is a variation of the standard Kuhn-Roth procedure, and hence what Kinney indicated as the methane yielding structure is obviously the methyl groups in coal. However, the relationship he pointed out can only be qualitative since true C-methyl content (as shown in the present work) cannot be obtained by any... 

Relative rates of sulfate reduction and methanogenesis in lakes of varying trophic status are claimed to indicate that sulfate reduction rates are limited by the supply of sulfate (4, 5, 13). According to this hypothesis, at high rates of carbon sedimentation, rates of sulfate reduction are limited by rates of sulfate diffusion into sediments, and methanogenesis exceeds sulfate reduction. In less productive lakes, rates of sulfate diffusion should more nearly equal rates of formation of low-molecular-weight substrates, and sulfate reduction should account for a larger proportion of anaerobic carbon oxidation. Field data do not support this hypothesis (Table II). There is no relationship between trophic status, an index of carbon availability, and rates of anaerobic...
