SYNERGISTIC EFFECTS OF EXPOSURE TO NOISE, HEAT STRESS AND INDOOR AIR POLLUTION ON MICE NEURAL BEHAVIORS

摘要

The indoor environment is always complex for people to analysis and understand, because it includes indoor air pollution, thermal comfort, acoustic environment and lighting environment, which make common influence on various human bodies and also the neural system. The paper aims to investigate neural symptoms of mice when they are exposed simultaneously to different levels of noise, heat stress and air pollution with various combinations.The experiment was accomplished in static envenoming chambers. The neural behavior test included spontaneous activity, darkness dodging and water maze. The neural behaviors of mice are observed under different artificial circumstances. The data received from all the tests are statistically calculated and processed by SPSS, a statistic software. A synergistic effect model is used to measure the strength of the influence from the individual environmental factors and their different combination effect. It is showed that the synergistic effect exists among the all three components of the indoor environment.
