In the past few decades, the results of epidemiological studies have shown that there is a significant relationship between human health and air pollution. The aim of this study was to quantify the health effects, the estimated number of cases of death, cardiovascular and respiratory deaths attributed to NO2 and SO2 pollutants in Bukan city by Air Quality software. Bukan city has a population o...

The effects of SO2 and NH3 on secondary organic aerosol formation have rarely been investigated together, while the interactive effects between inorganic and organic species under highly complex pollution conditions remain uncertain. Here we studied the effects of SO2 and NH3 on secondary aerosol formation in the photooxidation system of toluene/NOx in the presence or absence of Al2O3 seed aero...

Background: Sulfur dioxide is one of the important pollutants that at the present time cause irreparable damage to environment and human health. The aim of present study was to study and comparison the effects of SO2 on respiratory and cardiovascular deaths in Bushehr city. Materials and Methods: This analytical study was conducted in Bushehr city during 2011. In the first stage data were colle...

Introduction: Environmental features of the city of Zenica cause an increased risk of air pollutionrelated diseases in preschool children. Goal: The purpose of this paper is to examine a correlation between the air pollution-related diseases in preschool children and the average values of monthly concentration of sulfur dioxide (SO2) and total range of floating particles in the area of the city...

This study investigated the seasonal variation of ambient air quality status of Burdwan town using GIS approach. Concentration of SO2 (sulphur dioxide), NO2 (nitrogen dioxide) and RSPM (respiratory suspended particulate matter) were measured once a week for 24 hour in both premonsoon and postmonsoon season. The seasonal average concentration of the RSPM, SO2 and NO2 in premonsoon season was obs...

The use of sulphur dioxide (SO2) in the treatment of foodstuffs presents some problems as it could lead to pseudo-allergies in some people. The aim of this research work was to study the addition of different preservative mixtures and their influence on the concentration of volatile compounds and sensorial quality in wine. To do so, vinifications were carried out using Garnacha must to which ly...

Based on the TiO2 photocatalysis mechanism, a new method of simultaneous desulfurization and denitrification from flue gas was proposed. Preparation of TiO2 photocatalyst, design of photocatalysis reactor and influencing factors for simultaneous removal of SO2 and NO, and removal mechanism of SO2 and NO were studied. After the optimal values of concentration of O2 in flue gas, the relative humi...

In the present work, a sequential injection system with spectrophotometric detection was developed for the determination of free and total sulphur dioxide in wines. It was based on the formation of a coloured product from the reaction among SO2, formaldehyde and pararosaniline. A gas diffusion unit (GDU) was incorporated into the manifold to prevent the wine matrix interference in the spectroph...
