Health risk assessment of PM(2.5) on walking trips

PM(2.5) has an impact on residents' physical health during travelling, especially walking completely exposed to the environment. In order to obtain the specific impact of PM(2.5) on walking, 368 healthy volunteers were selected and they were grouped according to gender and age. In the experimen...

description PM(2.5) has an impact on residents' physical health during travelling, especially walking completely exposed to the environment. In order to obtain the specific impact of PM(2.5) on walking, 368 healthy volunteers were selected and they were grouped according to gender and age. In the experiment, the heart rate change rate (HR%) is taken as test variable. According to receiver operating characteristic (ROC) curve, the travel is divided into two states: safety and risk. Based on this, a binary logit model considering Body Mass Index (BMI) is established to determine the contribution of PM(2.5) concentration and body characteristics to travel risk. The experiment was conducted on Chang'an Middle Road in Xi'an City. The analysis results show that the threshold of HR% for safety and risk ranges from 31.1 to 40.1%, and that of PM(2.5) concentration ranges from 81 to 168 μg/m(3). The probability of risk rises 5.8% and 11.4%, respectively, for every unit increase in PM(2.5) concentration and HR%. Under same conditions, the probability of risk for male is 76.8% of that for female. The probability of risk for youth is 67.5% of that for middle-aged people, and the probability of risk for people with BMI in healthy range is 72.1% of that for non-healthy range. The research evaluates risk characteristics of walking in particular polluted weather, which can improve residents’ health level and provide suggestions for travel decision while walking.
