Epidemiologic studies of air pollution.

Modern Methods for Air Pollution

The monitoring of basic pollutants (sulphur oxides, nitrogen oxides, carbon monoxide, oxidants, hydrocarbons and particulate matter) to determine the air quality of a certain area is described. The performance of air monitoring by static, mechanized or automatic devices in point sensors and by remote and long-path sensors is discussed and further possibilities forecast. The evaluation of the st...

Prediction of Air Pollution Level Using System Identification Methods

For the prediction of the air pollution level, methods used in system identification can be used. In this case, the system will usually have a number of input parameters (mainly meteorological), and one output parameter, the pollutant concentration. For the pollutant generation and dispersion process, a model is to be developed that satisfies the experimental data (process parameters). This mod...

Power estimation using simulations for air pollution time-series studies

BACKGROUND Estimation of power to assess associations of interest can be challenging for time-series studies of the acute health effects of air pollution because there are two dimensions of sample size (time-series length and daily outcome counts), and because these studies often use generalized linear models to control for complex patterns of covariation between pollutants and time trends, met...
