Deformities and heartbeat rates of zebrafish larvae exposed to 44 nm nanopolystyrene particles (Nano-PS) in the presence of a real world environmental PAH mixture (Elizabeth River Sediment Extract – ERSE). Animals were co-exposed at 6 hours post fertilization (hpf) to 10 ppm Nano-PS and 1%, 2% or 5% ERSE. Deformities were assessed at 96 hpf (A – E) and the heartbeat rate at 48 hpf (F). Results are presented as scatter plot (n = 6 for deformities, n = 15 – 20 for heartbeat) and mean (black bar). Data were analyzed by two-way ANOVA followed by Tukey’s posthoc. Differences against the respective control group are shown as ** (p < 0.01) and *** (p < 0.001), while differences between ERSE and ERSE + Nano-PS exposures are shown as ## (p < 0.01) and ### (p < 0.001).
