Any other information on results incl. tables

2/6 animals died in the 2990 ppm group, 3/6 in the 4410 ppm and 5/6 in the 6290 ppm group. (LC50 ca. 4410 ppm) Clinical signs: Impairment of startle response from 359 ppm. At 2990 and 4410 ppm abnormal gait, impaired mobility, changes in arousal, hunched posture, irregular respiration. Approximate LC50 in mg/l: 4410 ppm * 90.55/24.45 * 1000 = 16.3 mg/l
