Qualitative picture of rate of deaths after an exposure reduction. The number of deaths per day, D, is shown versus time after the reduction. Thick solid line = observable deaths, thin dashed line = deaths shifted by pollution. a) temporary reduction of exposure, all individuals have the same gain ΔL. b) temporary reduction of exposure, distribution of different individual gains. c) permanent reduction of exposure, all individuals have the same gain ΔL.
