9901488PullinThe goal of the research is to determine whether or not amino acids and carbohydrates are released during photochemical decomposition of humic substances. If these compounds are observed, their rates of production will be quantified; then their importance in comparison to previously measured photoproducts can be determined. A mass balance including all observed carbon-based photoproducts would be determined. Then it can be determined whether all of the low-molecular weight carbon produced by the photolysis of humic substances is accounted for by the observed individual photoproducts. Long-term studies will allow a better understanding of the importance of these reactions in the global carbon cycle.

9901488 Pullin研究的目的是确定在腐殖物质的光化学分解过程中是否释放出氨基酸和碳水化合物。 如果这些化合物被观察到，它们的生产率将被量化;然后，它们的重要性与以前测量的光产物相比，可以确定。 将确定包括所有观察到的碳基光产物的质量平衡。 然后，可以确定是否所有的低分子量的碳产生的腐殖物质的光解是由观察到的个人的光产物。 长期研究将使人们更好地了解这些反应在全球碳循环中的重要性。
