OBJECTIVE To assess the lag structure between air pollution exposure and elderly cardiovascular diseases hospital admissions, by gender. METHODS Health data of people aged 64 years or older was stratified by gender in São Paulo city, Southeastern Brazil, from 1996 to 2001. Daily levels of air pollutants (CO, PM10, O3, NO2, and SO2) , minimum temperature, and relative humidity were also analyz...

In the recent years, artificial neural networks have been used to predict the concentrations of various gaseous pollutants in ambient air, mainly to forecast mean daily particle concentrations. The data on traffic air pollution, irrespective of whether they are obtained by measuring or modeling, represent an important starting point for planning effective measures to improve air quality in urba...

The effect of ambient air pollution on panic disorder in the general population has not yet been thoroughly elucidated, although the occurrence of panic disorder in workers exposed to organic solvents has been reported previously. We investigated the association of ambient air pollution with the risk of panic attack-related emergency department visits. Using health insurance claims, we collecte...

The survival of COVID-19 in different environments may be affected by a variety weather, pollution, and seasonal parameters. Therefore, the present study aims to conduct an ecological investigation on average growth rate daily cases deaths influenced environmental factors (temperature, humidity, air pollution) using sample size adjusted cumulative incidence based five 60-day periods. Research d...

This research paper is an attempt towards analyzing real time air pollution data collected by PAQS sensor devices from some key locations in Bangalore. Air pollution in most of the metropolitan cities in India is turning out to be a major threat to our environment and hazardous to our health. Many infections and diseases related to lungs and throat are caused by the polluted air we breathe. The...

The association between daily cardiovascular/respiratory mortality and air pollution in an urban district of Beijing was investigated over a 6-year period (January 2003 to December 2008). The purpose of this study was to evaluate the relative importance of the major air pollutants [particulate matter (PM), SO2, NO2] as predictors of daily cardiovascular/respiratory mortality. The time-series st...

atmospheric visibility has been defined as the greatest distance at which an observer can see a black object viewed against the horizon sky, which in quantitative terminology is known as visual range. visibility, in the absence of special meteorological events (e.g. rain and fog), is an excellent indicator of air quality. visibility impairment results from light scattering and absorption by atm...

Air pollution forecasting is the most important environmental issue in urban areas as it is useful to assess the effects of air pollutants on human health. It has been observed that the air pollution has been increased above the standard level in the urbanized area of Delhi and will be a major problem in the next few years. Therefore, the main objective of the present study is to develop the mo...

air pollution is one of the major threats to environment in the present time. increase in degree of urbanization is a major cause of this air pollution. due to urbanization, vehicular activities are continuously increasing at a tremendous rate. mobile or vehicular pollution is predominantly degrading the air quality worldwide. thus, air quality management is necessary for dealing with this seve...
