Acute nPM exposure of L1 worms results in adult worm size reduction. (A) Dose-dependent size changes (mean ± SEM) of Day 1 adult animal body area following 1 hour exposure to nPM in L1 stage (n = 3*15 to 22 /group). The average area of the control group was 0.06 mm² with average length of 0.97 mm. (B) Pharyngeal pumping rate of animals (n = 3*~7/group) analyzed at 24 hours post-exposure of the L1 stage wildtype animals to 200 μg/mL nPM. Statistical tests include analysis of variance followed by Tukey post hoc with correction for multiple statistical hypothesis testing for size and t test for pharyngeal pumping. Adjusted p-values: <.05 (*), <.01(**), <.001(***), <.0001(****).
