Project Description:
Ultraviolet filter chemicals (UVFCs) detected in surface waters and biota are listed active ingredients for numerous Pharmaceuticals and Personal Care Products. The fate of UVFCs in the aquatic environment will affect the relative potential for bioaccumulation and toxicity, and little is currently known about potential elimination processes. My research will consider the breakdown of three FDA-approved UVFCs in purified laboratory, model, and natural surface waters under simulated and natural UV light conditions. Results from these experiments will indicate the relative importance of direct and indirect photolyses and the effects of seasonal variablity. Our goal is to identify formed chemical species and to calculate environmental half-lives of these UVFCs in surface waters.
