Project Summary (1995-2000)

The major thrust of this research project is to utilize a physicochemical model to determine significant factors which relate recalcitrance to the degradation, persistence, and fate of azo dyes, related dyestuffs and their degradation or biotransformation products in the environment. Two objectives are proposed for this research, with specific aims central to the laboratory and providing opportunities for collaborative research with colleagues in other projects of this application. The specific aims of this project are to investigate the determinants of the abiotic stability of azo dyes, the determinants of the biotic stability of azo dyes, and the intrinsic and extrinsic factors that impact the biological and chemical processes determining the persistence and fate of azo dyes and related compounds.
