Traffic related air pollutants shorten life expectancy ====================================================== * A Bhowmik ▴ Hoek G, Brunekref B, Goldbohm S, *et al*. Association between mortality and indicators of traffic-related air pollution in the Netherlands: a cohort study. Lancet2002;360:1203–9.

The patients were contacted every 2 years from 1986 to 1994 to determine migration and to assess vital status and deaths. There were 489 deaths in this period. Cardiopulmonary mortality was associated with living near a major roadway—that is, 100 m from a highway or 50 m from a main road (relative risk 1.95, 95% CI 1.09 to 3.52). This paper is yet further evidence that air pollutants or some closely associated pollutant from road traffic contribute to cardiopulmonary mortality.
