Reproduction function and embryo's abnormal development easily happen to women. Show according to the survey of more than 200 computer operators of banking system in Wuhan, such symptoms as over 35% of the women present menstruation, lengthen in menstrual period, premature delivery take place or miscarry to a few women.

The ozone gas is not only poisonous, but also may cause some people to have difficulty in breathing. To those asthma and anaphylaxis patient, the situation is more serious. In addition, stay in the place taller in density in ozone gas for longer time, will also cause pathological change take place in the lung.
