published an interesting article by Henry Loi on pollution caused by pollution emitted by passenger cars. To you the considerations universe and especially a bold reflection.
long-term exposure to air pollution to vehicle emissions may decrease life expectancy, traffic density and distance of residence from major roads can be considered predictive of differences in the concentrations of nitrogen dioxide in the air. If an association between particulate pollution and cardiopulmonary disease had already observed, confirmation comes from a large prospective study published in the Lancet (2002, 360: 1203-1209).
The search, which lasted eight years - collected data between 1986 and 1994 - and conducted in the Netherlands, involved five thousand individuals aged between 55 and 69 years, 64 percent of them men. Aims of the work were to assess the exposure to aeroinquinanti, especially the black smoke (particulate pollution, mainly due to elemental carbon emitted by diesel engines) and nitrogen dioxide (from all motor vehicles) and measure the cause-mortality specifically connected. The data obtained showed an increased relative risk of death from cardiovascular disease associated with a background air pollution level of 10 pg nero/m3 smoke. This increase is not statistically significant, however, reinforces similar evidence obtained from previous studies. They also tested the variation in risk depending on the proximity to areas of the dwelling or not particularly busy. The data obtained confirm the suspected: the majority of 11 percent of the participants died during the study died from cardiovascular disease and pulmonary and cardio-pulmonary mortality was significantly correlated to the proximity of the dwelling to the main streets. In particular, it was noted that live within a hundred yards from a highway or within fifty to a main road further increases the risk of cardiovascular death, which is almost one and half times higher than that attributable to only background pollution. Less important, however, appeared The influence of factors such as noise from traffic, poor diet and alcohol consumption. Finally, independent results of air pollution deaths due to diseases other than heart and lungs and the tumor load in the lung. It is emphasized, however, are not necessarily black smoke and nitrogen dioxide to cause increased mortality, but these substances are good indicators of the level of aeroinquinamento. Obviously, further research is needed on the subject, but the results of the study, the authors, however, should suggest some changes in health policy: they should be assumed that the vehicle emissions and those due to combustion continue to be a major source of particulates in the world. The increasingly obvious link between the dust and the risk of cardio-pulmonary mortality so strongly emphasizes the need for action at local level. The research is published in the journals "Lancet" & "Journal of the doctor" (author: Paola Gregori).
