BACKGROUND A number of epidemiological studies have been conducted to research the adverse effects of air pollution on mortality and morbidity. Hypertension is the most important risk factor for cardiovascular mortality. However, few previous studies have examined the relationship between gaseous air pollution and morbidity for hypertension. METHODS Daily data on emergency hospital visits (EH...

We examine the relationship of air pollution and climatic variables to asthma admission rates of children in Galway city over a 21 year period. Paediatric asthma admissions were recorded from 1985-2005, and admission rates per thousand calculated for pre-school (1-4 years), school aged (5-14 years) and all children (1-14 years) on a monthly and annual basis. These data were compared to average ...

The major wheat production region of China the North China Plain (NCP) is seriously affected by air pollution. In this study, yield of winter wheat (Triticum aestivum L.) was analyzed with respect to the potential impact of air pollution index under conditions of optimal crop management in the NCP from 2001 to 2012. Results showed that air pollution was especially serious at the early phase of ...

BACKGROUND Preventing suicide is a global imperative. Although the effects of social and individual risk factors of suicide have been widely investigated, evidence of environmental effects of exposure to air pollution is scarce. We investigated the effects of ambient air pollution on suicide mortality in Guangzhou, China during 2003-2012. METHODS A conditional logistic regression analysis wit...

results there was a significant positive correlation between increase in the monthly average temperature, the number of rainy days, and the number of frost days with the number of rta (p < 0.05). increased monthly average relative humidity, evaporation, and number of sunny days were negatively correlated with the frequency of rta (p < 0.05). we also observed an inverse significant correlation b...

Pollution: Associations Persist with Continued Advances in Research Methodology (See Neas et al., p. 629; Lee and Schwartz; p. 633; and Fairley, p. 637) In this issue of Environmental Health Perspectives there are papers by Fairley, Neas et al., and Lee and Schwartz. Although these papers present different approaches, they provide a reasonable representation of stateof-the-art epidemiologic res...

OBJECTIVE Current levels of ambient air pollution are associated with morbidity and mortality in the general population. To determine the influence of gaseous air pollutants on neonatal respiratory morbidity, we tested the association between daily respiratory hospitalizations and daily concentrations of ambient air pollution gases: ozone, carbon monoxide, sulfur dioxide, and nitrogen dioxide, ...

Air pollution is a major factor of consideration in the evaluation of quality of life and as an environmental issue in urban areas. Among urban air pollutants carbon monoxide (CO) is one of the most prevalent. Information about its concentrations is vital in the determination of urban air pollution. In this paper, an automatic and cost effective prototype for CO monitoring and mapping is presen...

The pattern of economic growth that we are adopting is increasingly associated with environmental pollution. It is clear that in the developing or developed countries increased mechanization, transportation, populations, etc. causes air pollution which is a major and effective environmental problem. Present study focuses on analysis of air pollution in Kannur city of Kerala. In this study, pred...

The aim of this study is to quantify the impacts of air pollution and meteorological parameters on human morbidity and to test whether different model specifications and approaches yield different results. Generalised additive and linear models along with monthly time series data for CO, NO, NO2, SO2, O3, average/maximum/minimum air temperature, relative humidity and atmospheric pressure are em...
