Photoenhanced toxicity is the increase in the toxicity of a chemical in the presence of ultraviolet light compared to a standard laboratory test conducted with fluorescent lighting.
Since standard dispersants toxicity testing has traditionally been conducted in a laboratory setting with fluorescent lighting, the council wanted to know how natural lighting might affect the toxicity of chemically dispersed oil. Photoenhanced toxicity, it turns out, is a factor that needs to be considered when chemically dispersing oil into the waters of Prince William Sound and the Gulf of Alaska.

Hydrocarbon Toxicity
Through our Hydrocarbon Toxicity Project, we research and address the gaps in knowledge regarding chronic toxic effects of oil, dispersed oil and in-situ burn (burning spilled oil) residue under study conditions similar to the cold marine waters in our region.
