Combining with the data of Chinese body feature

the influence of age

gender and physical activity level on indoor occupant pollution source emission is analyzed based on emitting mechanism and characteristics of typical occupant pollutants. Method to determine the amount of carbon dioxide reduction caused by unstable factors of occupant body odor pollution is obtained with unsteady coefficient. Also

the effective emission model of occupant pollution source is presented according to superposition relationship between carbon dioxide production and reduction. It is shown that there exists difference between carbon dioxide emission level of male and that of female. Carbon dioxide emission level of human body is affected by age and gender. Moreover

the impact of occupant body odor pollution unstable factors on carbon dioxide reduction rate has significant change stage and relatively stable stage

which has connection with air change rate and occupant pollution source action time.
