Some case studies on the investigation of anthropogenic loading of river sediments by organic compounds are given in the literature. For example, WENNING et al. [1993] describe the chemometric analysis, by means of PCA, of potential sources of polychlorinated dibenzo-p-dioxins and dibenzofurans in surface sediments.

The principal direction of the published photochemical research to date has been to elucidate pathways which might be responsible for the degradation of these refractory substances in nature. This basic research has not been extensively applied either to on-or off site treatment of hazardous substances. In this chapter we extend the existing PCB photochemistry literature by considering this potential. The development and fabrication of a prototype surface photoreactor, and its preliminary evaluation at a PCB-contaminated site are described. Photochemical treatments may be applicable to many other classes of hazardous chemicals as well including the polychlorinated dibenzodioxins (PCDD) and dibenzofurans (PCDF) about which this monograph is chiefly concerned.
