Latent Toxicity in Adult Zebrafish Following Early Life Stage Exposure to 2,3,7,8-Tetrachlorodibenzo-p-Dioxin
Exposure to 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) in the early stages of fish development can have lasting influence. Sublethal concentrations of TCDD may adversely affect feeding, predation-avoidance behavior and reproduction in wild fish populations. This new project will use the small, nearly transparent zebrafish to determine whether sublethal levels of TCDD can disrupt development, damage organs, inhibit feeding, affect body growth, or diminish reproduction. Building on previous and continuing work by these investigators, this project will help determine whether such effects are permanent or reversible.
