Measurement of the movement of Paramecium in the presence of organic pollutants. (A) Movement of Paramecium in Erythromycin solutions. The color code of the graph is similar to that in Fig. 2. The PL of erythromycin is 0.1 µg/l. Paths at the right side are for PL (light purple) five times PL (dark purple). (B) Swimming speed of Paramecia in samples contaminated with tetrachloroethylene (PL = 40 µg/l). Paths are for PL (blue) and five times PL (yellow). (C) Same representation but for trichloroethylene at (PL = 20 µg/l). Error bars represent standard deviation of the average speeds, and the paths are represented over the whole area of the chamber. Statistical significances are analyzed in Supplementary Fig. 2 and cumulative distances in Supplementary Fig. 4.
