Degradation studies method development

In the study of a discoloured ancient wood from a Buddhist building constructed before or during the eighth century AD, concentrations show the same kind of evolution. Moreover, the levels of extractives in the ancient wood are comparable to those in recently cut wood, meaning that they do not undergo degradation in the ancient wood. The method developed on recently cut wood is then applicable to old discoloured wood. 

For o-, p-, and m-cresol, as well as the mixed isomers, anaerobic degradation studies, analytical methods development, and transformation studies are all on-going (EPA 1989b). Additionally, for o-cresol, studies on water purification techniques are on-going, while for p- cresol, aerobic degradation and toxicity studies are on-going. 

The studies with sediment cultures indicate natural degradation potential for aquatic sediments exposed to anthropogenic CP pollution. However, in situ remediation rates for CP-contaminated sediments may be difficult to enhance. Possibilities involve nutrient and electron donor/acceptor amendments. Ex situ remediation could involve sediment dredging and application of methods developed for soil decontamination, such as slurry reactors and composting.
