  • Outdoor Air Pollution and asthma
    The Lancet, 2014
    Co-Authors: Michael Guarnieri, John R Balmes

    Abstract:

    Traffi c and power generation are the main sources of urban Air Pollution. The idea that outdoor Air Pollution can cause exacerbations of pre-existing asthma is supported by an evidence base that has been accumulating for several decades, with several studies suggesting a contribution to new-onset asthma as well. In this Series paper, we discuss the effects of particulate matter (PM), gaseous pollutants (ozone, nitrogen dioxide, and sulphur dioxide), and mixed traffi c-related Air Pollution. We focus on clinical studies, both epidemiological and experimental, published in the previous 5 years. From a mechanistic perspective, Air pollutants probably cause oxidative injury to the Airways, leading to infl ammation, remodelling, and increased risk of sensitisation. Although several pollutants have been linked to new-onset asthma, the strength of the evidence is variable. We also discuss clinical implications, policy issues, and research gaps relevant to Air Pollution and asthma.

  • Air Pollution forecast in cities by an Air Pollution index highly correlated with meteorological variables
    Atmospheric Environment, 2001
    Co-Authors: Euro Cogliani

    Abstract:

    There are many different Air Pollution indexes which represent the global urban Air Pollution situation. The daily index studied here is also highly correlated with meteorological variables and this index is capable of identifying those variables that significantly affect the Air Pollution. The index is connected with attention levels of NO2, CO and O3 concentrations. The attention levels are fixed by a law proposed by the Italian Ministries of Health and Environment. The relation of that index with some meteorological variables is analysed by the linear multiple partial correlation statistical method. Florence, Milan and Vicence were selected to show the correlation among the Air Pollution index and the daily thermic excursion, the previous day’s Air Pollution index and the wind speed. During the January–March period the correlation coefficient reaches 0.85 at Milan. The deterministic methods of forecasting Air Pollution concentrations show very high evaluation errors and are applied on limited areas around the observation stations, as opposed to the whole urban areas. The global Air Pollution, instead of the concentrations at specific observation stations, allows the evaluation of the level of the sanitary risk regarding the whole urban population.
