OBJECTIVE Environmental air pollution has become a leading health concern especially in the developing countries with more urbanization, industrialization and rapidly growing population. Prolonged exposure to air pollution is a risk factor for cardiovascular diseases. The present study aimed to investigate the effects of environmental air pollution on progression of cardiovascular problems. M...
Outdoor and indoor air pollution poses a significant cardiovascular risk, and has been associated with atherosclerosis, the main underlying pathology in many cardiovascular diseases. Although, it is well known that exposure to air pollution causes pulmonary disease, recent studies have shown that cardiovascular health consequences of air pollution generally equal or exceed those due to pulmonar...
Background and objectives: Tehran is one of the most polluted cities in the world in terms of air pollution. Modeling is a useful tool in air pollution management. The objectives of this study are to determine the distribution of the main air pollutants concentration in Tehran and to construct a photochemical model appropriate to the geography and natural characteristics of Tehran. Methods: I...
Urban air pollution levels are associated with increased mortality and cardiorespiratory morbidity. These health effects occur even at exposure levels below those stipulated in current air-quality guidelines, and it is unclear whether a safe threshold exists. Air pollution in Australia and New Zealand comes primarily from motor vehicle emissions, electricity generation from fossil fuels, heavy ...
O nce a severe but local problem of highly industrialised and densely populated cities, air pollution has now morphed into a more insidious threat to the public health of entire nations. Smoke from domestic coal fires, power plants and heavy industry has largely vanished from our skies. This has been achieved through the use of clean fuels, filtration of flue gases, improvements in process tech...
PEDIATRIC ASPECTS OF AIR POLLUTION P UBLIC concern regarding air pollution has increased rapidly in recent years. Because air pollution may present special problems in the pediatric age group, available information on the effects of various air pollutants on children has been reviewed with the purpose of: ( 1 ) defining the potential ill effects of air pollution in this age group, (2) making in...
Exposure to ambient air pollution is a serious and common public health concern associated with growing morbidity and mortality worldwide. In the last decades, the adverse effects of air pollution on the pulmonary and cardiovascular systems have been well established in a series of major epidemiological and observational studies. In the recent past, air pollution has also been associated with d...
A statistical association between ambient air pollution and suicide mortality has been recently reported in Environmental Health, which seems not to be scientifically supported by their data.In this article, very low (unrealistic) suicide rate is reported, which is subjected to selection bias. Their justification is also flawed as high exposure to ambient air pollution in rural areas is lower a...
Escalating air pollution is contributing to increased cardiovascular health problems currently witnessed in the world. Cardiac diseases such as ischaemic heart disease and strokes account for 80% of ambient air pollution-related early deaths [1]. Additionally, it is estimated that about 3 million deaths and 85 million disability adjusted live years (DALYs) resulted from particulate matter of am...
introduction: the process of urbanism in countries that are developing, like islamic republic of iran with increasing of the number and the size of cities and the fast accepting of population have been caused the forming of problems like an in-official economics and in-official settlement and was become creating high population in main and old places of city and increasing of air pollution and ...
