| Abstract: | Based on measured data, the prediction model of PAEs concentration in childrens bedroom was established by back propagation (BP) neural network with various influencing factors of phthalates (PAEs) as independent variables and PAEs concentration as dependent variables. The results showed that the prediction effect of this model was ideal, the ratios of STD were all greater than 0.5, NMB were all close to 0 and EMR were all less than 19%. According to the relevant data from a research of indoor environment and childrens health in Tianjin, the concentration of DEHP was predicted. The EMR between average measured value and average predicted value was 7.7%, indicating that the prediction accuracy of the model was high. |
