The study measures exposure to air pollution in an urban setting in India. Integrated daily exposure to respirable suspended particulates (RSP) and carbon monoxide (CO) was assessed by personal and area sampling from six micro-environments including those for which prior data did not exist in India. This is also one of few studies that have measured the exposure of commuters on motor cycles, scooters, etc. A time budget survey was conducted to determine how much time people spend in these micro-environments. A sample of 1100 households (4311 individuals) was chosen randomly from 32 localities in Delhi for an activity patterns survey.
