摘要:
Two groups of Mongolian gerbils (Meriones unguiculatus) were continuously exposed to 150 ppm trichloroethylene (TCE) for 77 and 106 d, respectively. The behavior of the animals was tested in a symmetrical maze baited with sunflower seeds during a period of 23 d, beginning at the end of exposure. One additional group was exposed for 150 d and then allowed 40 d free from exposure before the start of the maze test Comparisons between the TCE‐ and air‐exposed animals showed differences in the number of correct choices and the number of seeds consumed in the maze, both after 71 and 106 d of exposure and at the end of the 40‐d rehabilitation period that followed the 150‐d exposure. The results were interpreted in terms of the “emotionality” of the animals.
