چکیده

Riassunto: Negli ultimi anni molti studi sono stati condotti al fine di valutare la presenza di una eventuale associazione tra inquinamento dell’aria e mortalità. La relazione tra le concentrazioni di inquinanti e mortalità (o morbosità) nel medesimo giorno, o nei giorni successivi, viene usualmente specificata mediante modelli di regressione in cui la variabile di risposta è il numero di morti (o ricoveri) giornalieri e in cui le variabili esplicative, in aggiunta agli inquinanti, sono variabili ambientali e meteorologiche. Generalmente per evitare problemi di collinearità le analisi vengono condotte per i singoli inquinanti. Nel presente lavoro si indaga come sia possibile tener conto dell’effetto di tutti gli inquinanti mediante l’uso di indici di qualità dell’aria come variabile esplicativa, in alternativa o in aggiunta al singolo inquinante.

Air pollution exposure monitoring and estimating

This paper presents an integrated exposure monitoring system, based on an expansion of existing air quality monitoring systems using dispersion modelling. The system allows: (1) identifying geographical areas whose inhabitants are most exposed to ambient pollution; (2) identifying how many people in an area are exposed to concentrations of pollution exceeding air quality guidelines; (3) describ...

Use of an index to reflect the aggregate burden of long-term exposure to criteria air pollutants in the United States.

Air pollution control in the United States for five common pollutants--particulate matter, ground-level ozone, sulfur dioxide, nitrogen dioxide, and carbon monoxide--is based partly on the attainment of ambient air quality standards that represent a level of air pollution regarded as safe. Regulatory and health agencies often focus on whether standards for short periods are attained; the number...

سنجش تأثیر آلودگی هوا بر هزینه‌های بخش سلامت در ایران

Introduction: One of the main challenges in the field of health economics is detecting the factors affecting on health costs. One of the these factors is air pollution, which has been ignored in most of empirical studies; while air pollution is one of the environmental problems which in recent years has become a serious threat to human health. Therefore, the aim of this study was to evaluate th...

Integrated systems for forecasting urban meteorology, air pollution and population exposure

Urban air pollution is associated with significant adverse health effects. Model-based abatement strategies are required and developed for the growing urban populations. In the initial development stage, these are focussed on exceedances of air quality standards caused by high short-term pollutant concentrations. Prediction of health effects and implementation of urban air quality information a...

Ecological bias in studies of the short-term effects of air pollution on health

There has been a great deal of research into the short–term effects of air pollution on health with a large number of studies modelling the association between aggregate disease counts and environmental exposures measured at point locations, for example via air pollution monitors. In such cases, the standard approach is to average the observed measurements from the individual monitors and use t...
