Abstract
A novel chamber for maintaining aqueous phase dispersions of nanoparticles (NPs) to enable improved toxicity testing in larval zebrafish was developed. Aqueous concentrations were within 80% of initial NP concentrations, and 96-h LC50 values were highly reproducible (coefficient of variation <0.16, n=3 tests). Significantly lower toxicity for each NP tested (Ag-, Cu-, TiO2 -NPs) in static beakers suggested that traditional acute toxicity tests may underestimate aqueous phase toxicity of NPs.
