Air quality in Hyderabad, India, often exceeds the national ambient air quality standards, especially for particulate matter (PM), which, in 2010, averaged 82.2 ± 24.6, 96.2 ± 12.1, and 64.3 ± 21.2 μg/m(3) of PM10, at commercial, industrial, and residential monitoring stations, respectively, exceeding the national ambient standard of 60 μg/m(3). In 2005, following an ordinance passed by the Sup...

Air quality is one of the main priorities for the improvement of the life quality in urban regions, as air pollution is usually, concentrated in such densely populated areas. Most of the countries have a national air quality monitoring network that allow an analysis of the air quality status, especially for urban regions that are nodes in this network. As the network is geographically distribut...

UNLABELLED Multiple linkages connect air quality and climate change. Many air pollutant sources also emit carbon dioxide (CO2), the dominant anthropogenic greenhouse gas (GHG). The two main contributors to non-attainment of U.S. ambient air quality standards, ozone (O3) and particulate matter (PM), interact with radiation, forcing climate change. PM warms by absorbing sunlight (e.g., black carb...

Ozone is one of the most severe air pollution problems in the world. The concentration of ozone in the troposphere is of great interest because of its negative influence on the human health, vegetation and materials. The complexity of ozone (O3) formation mechanisms in the troposphere, the complexity of meteorological conditions in urban areas and the uncertainty in the measurements of all the ...

introduction air pollution is one of the critical challenges in metropolitans around the world. according to world health organization (who), three millions people die from air pollution annually. in some studies mortality costs by air pollution was estimated. social cost of air pollution was estimated 28990 billions rials in tehran city. the mortality cost by air pollution was estimated about ...

Over the past two decades, epidemiological studies have strengthened the link between air pollution and specific respiratory ailments, yielding better valuations for the pollution-related costs of illness and thus pinpointing the benefits of environmental regulations. Much work remains to be done, however, in linking air pollution to other important health outcomes, such as cancer, infant morta...

Background: Prenatal exposures to stress and physical toxins influence children’s respiratory health, although few studies consider these factors together. Objectives: We sought to concurrently examine the effects of prenatal community-level psychosocial (exposure to community violence [ECV]) and physical (air pollution) stressors on repeated wheeze in 708 urban children followed to age 2 years...

Indoor air pollution due to the indoor burning of polluting fuels has been associated with Acute Lower Respiratory Infections (ALRI) amongst children less than five years old. This paper reviews evidence of the association between household energy, indoor air pollution and child ALRI in South Africa. Studies show evidence consistent with the international literature with the likelihood of ALRI ...

BACKGROUND THE APHENA (AIR POLLUTION AND HEALTH: A Combined European and North American Approach) study is a collaborative analysis of multicity time-series data on the effect of air pollution on population health, bringing together data from the European APHEA (Air Pollution and Health: A European Approach) and U.S. NMMAPS (National Morbidity, Mortality and Air Pollution Study) projects, along...
