To deal with the worsening sanitation of public toilets, Chinese government put forward the plan of “Revolution of Toilets” in 2015, which has achieved some research results about improved sanitary condition of independence public toilets and dependence public toilets. However, the sanitary condition of Mobile Public Toilets (MPT), which are used outdoor remains unchanged due to the limits of water supply and the lack of ventilation facilities. In order to find out the influence factors of the internal sanitary of the MPT, in this paper, three groups of normally used MPT in Zhengzhou have been selected as the research objects and thermal environment parameters were measured in summer. In addition, subjectively scoring method has been used synchronously for odor intensity evaluation by six grades. The measured thermal environments and scored odor intensity inside the three objects MPT demonstrated that the indoor environment of MPT is highly unacceptable even for short-term use in summer, appropriate measures should be taken to improve the thermal environments and remove malodor in MPT.
