  1. Cd is the air pollution level at front door location, Ch represents the air pollution concentration for the activity being at home, Cp the air pollution concentration for the activity playing in the neighbourhood, Ct for travelling and Cs for being at school, E represents the individual exposure after applying Eq. 1
