Abstract

Butyl benzyl phthalate (BBP) is found in common household and industrial products world-wide. Phthalates are not covalently bound to plastics and continuously leach into the soil, sediment and aquatic environments. The lateral line system of fish is a mechanosensory system composed of neuromasts essential for survival behaviors including rheotaxis, schooling and predator avoidance. Here, we investigated the developmental toxicity of BBP on the developing lateral line neuromasts in zebrafish. Embryos were treated at gastrula stage with BBP and analyzed by DASPEI staining at 4 days post fertilization. We find that BBP negatively affects neuromast development leading to loss of DASPEI signal in neuromasts in a concentration dependent manner.
