ly coal combustion, are major contributors to air pollution. Concentrations of suspended particles and sulfur dioxide (SO2) in the air of many cities in developing countries exceed World Health Organization standards1. The effects of this pollution on human health can be devastating and in the most seriously affected countries the economic costs are estimated to be a significant percentage of G...
Pollution levels and the effect of air pollution on human health can be modified by synoptic weather type and aeroallergens. We investigated the effect modification of aeroallergens on the association between CO, O3, NO2, SO2, PM10 and PM2.5 and asthma hospitalisation rates in seven synoptic weather types using single air pollutant models, adjusted for the effect of aeroallergens and stratified...
This study explores the relationship between happiness and air pollution in Britain using data from the British Household Panel Survey (BHPS). The effects of air pollution on individuals’ happiness are estimated and their monetary value is calculated. In particular, three air pollutants are examined in this paper; the sulphur dioxide (SO2), the ground-level ozone (O3) and the nitrogen dioxides ...
BACKGROUND A study was performed to determine whether daily and weekly variations in the levels of smoke and sulphur dioxide (SO2) in Birmingham are related to hospital admissions for asthma and acute respiratory diseases. METHODS Daily numbers of hospital admissions for asthma (ICD code 493) and acute respiratory conditions (ICD 466, 480-486, 490-496) for residents of Birmingham between 1988...
Background & Aims: Poor air quality regarding harmful consequences as one of the most important environmental problems have challenged many metropolises. Since exposure to these pollutants can affect human health, this study aimed to investigate the health effects of SO2 and PM10 attributable to the air pollution on the health of the Urmia citizens in 2013 using software AirQ. Materials...
Background. Sudden infant death syndrome (SIDS) affects 1 in 1000 live births and is the most common cause of infant death after the perinatal period. Objective. To determine the influence of air pollution on the incidence of SIDS. Methods. Time-series analyses were performed to compare the daily mortality rates for SIDS and the daily air pollution concentrations in each of 12 Canadian cities d...
Ladan Bayat 1, Mehri Askari*2 Department of Biology, Faculty of Science, Arak University (Received: 29 November 2012 Accepted: 4 May 2013) Abstract: Plant growth promoting rhizobacteria are beneficial bacteria that increase growth of plants and induce resistance to various stresses. SO2 air pollution is one of these stresses that is known as a strong damaging air pollutants. Pers...
A large SO2-rich pollution plume of East Asian origin was detected by aircraft based CIMS (Chemical Ionization Mass Spectrometry) measurements at 3–7.5 km altitude over the North Atlantic. The measurements, which took place on 3 May 2006 aboard of the German research aircraft Falcon, were part of the INTEX-B (Intercontinental Chemical Transport Experiment-B) campaign. Additional trace gases (NO...
Bor and the surroundings (Eastern Serbia) have a poor air quality, due to emissions from the miningmetallurgical complex for copper production. Considering the processing and smelting of sulphide ores, one of the dominant air pollutant is SO2, which causes acidification of waters and soil, affecting vegetation. Biomonitoring of air pollution was conducted in order to examine the effect of the i...
The aim of this study was to investigate the association between daily changes in respiratory health and air pollution in 489 adults, aged 50-70 yrs, with and without chronic respiratory symptoms, living in urban and nonurban areas in the Netherlands. Subjects were selected from the general population with a screening questionnaire. During three consecutive winters starting in 1992/1993, peak e...
