Figure 1. Genetic variation influences the susceptibility of C elegans to the toxic effects of traffic-derived particulate air pollution:First larval stage (L1) N2 (A), DR1350 (B), or CB4856 (C) animals were either mock exposed (M9), exposed to paraquat (PQ), or exposed to traffic-derived nanoparticulate matter (nPM) for 1 h. The resultant body size after 3 d of recovery is indicated as a percent of the average size of animals exposed only to M9, which was set equal to 100%. D) To determine which genotype is most susceptible to nPM, the relative animal size of each genotype upon exposure to nPM was plotted side-by-side. For every graph, symbols represent the relative size of a single animal with n=16-34 individuals. Bars represent the mean relative animal size. Error bars represent the standard error of the mean. To identify statistically significant differences between samples, post hoc analyses were performed using the Bonferroni multiple comparisons test. P-values are indicated on graphs except in cases where the p-value was greater than 0.05 (not significant, n.s.). E) Representative micrographs of live animals 3 d after acute exposure, which were all taken at the same magnification.
