PFOS and PFBS significantly impaired the reproduction capacities of wild type C. elegans. Synchronized L4/young adult worms were treated with control (0.1% DMSO) or PFOS or PFBS for 1 day at 20°C. After treatment, worms were randomly selected for the reproduction analysis. Daily brood size and progeny number were recorded until the reproduction was ceased. Broodsize (A) was determined by counting the laid egg numbers. Progeny numbers (B) were recorded as the number of the hatched-out offspring. Hatchability (C) was calculated as progeny number/broodsize. Results are expressed as mean±S.E (n=21-24, collected from 4 independent experiments). a,b,c Means with different letters are significantly different (P<0.05).
