Ambient (outdoor) air pollution is now recognized as an important problem, both nationally and worldwide. Our scientific understanding of the spectrum of health effects of air pollution has increased, and numerous studies are finding important health effects from air pollution at levels once considered safe. Children and infants are among the most susceptible to many of the air pollutants. In a...

background: measuring and monitoring of air pollutants are one of environmental and all' pollution controls tools. due to lack of widespread data in iran, this study was performed to estimate the trends of major pollutant emissions to atmosphere in the uk from 1980 to 1996. methods: this investigation is a retrospective study that the data were collected from the departments of environment, tra...

The health effects of air pollution include increases in Air pollution on Pdient visits in &be 1 severity and incidence of asthma. exacerbation of COPD. increase California faces both increasing air temperatures as well as air pollution. This conclusion is being drawn by many non-scientists who simply observe daily atmospheric conditions: more hot days exist in many areas of California and many...

Exposure to high levels of air pollution can cause a variety of adverse health outcomes. Air quality in developed countries has been generally improved over the last three decades. However, many recent epidemiological studies have consistently shown positive associations between low-level exposure to air pollution and health outcomes. Thus, adverse health effects of air pollution, even at relat...

background & purpose: air pollution has been known as one of the most effective factors on cardiovascular, pulmonary and infectious diseases. this study aims to determine the relation between mortality rate and air pollution in mashhad during 2007-2009. materials & methods: data of air pollution, mortality rate and geographic factors were collected during 2007-2009 and analyzed. mortality rate,...

IN T R O D U C T IO N In recent years there has been a growing concern about the rapidly deteriorating environment in the urban areas of this country in terms of air, water, and noise pollution. Automobile transportation has been found to be a significant factor in the deterioration of the urban environment, particularly in regard to air pollution. In general, con­ sidering the total tonnage of...

The present study applies the model of American Meteorological Society-Environmental Protection Agency Regulatory Model (AERMOD) to investigate NO2 emissions from Besat thermal power plant, which is fuelled by natural gas to function. Results indicate that the simulated concentration of NO2 based on AERMOD, does not exceed NO2 concentration limit, set by the Iranian Ambient Air Quality Standard...

The East Mediterranean region suffers from high levels of air pollution which has a negative impact on pregnancy outcomes. This work systematically reviews the epidemiological evidence on maternal exposure to air pollution and adverse pregnancy outcomes in the region. Relevant papers and reports published between 2000 and 2014 were searched. Combinations of search terms including countries, exp...

Air pollution and lung cancer are closely related. In 2013, the World Health Organization listed outdoor air pollution as carcinogenic and regarded it as the most widespread carcinogen that humans are currently exposed to. Here, grey correlation and data envelopment analysis methods are used to determine the pollution factors causing lung cancer among residents in Nanchang, China, and identify ...

Under clean and green revolution programme, an urgent need has been felt to develop mitigation devices and pollution control instruments. Through this paper, discussion has been made on pollution thrust emanating in atmosphere from stacks and its control through indigenous technology and control instruments developed in India to meet the techno-economical needs of country. Main emphasis has bee...
