[1] We investigate the effects on U.S. ozone air quality from 2000–2050 global changes in climate and anthropogenic emissions of ozone precursors by using a global chemical transport model (GEOS-Chem) driven by meteorological fields from the NASA Goddard Institute for Space Studies general circulation model (NASA/GISS GCM). We follow the Intergovernmental Panel on Climate Change A1B scenario an...
Tobacco smoke air pollution (TSAP) measurement may persuade parents to adopt smoke-free homes and thereby reduce harm to children from tobacco smoke in the home. In a pilot study involving 29 smoking families, a Sidepak was used to continuously monitor home PM(2.5) during an 8-h period, Sidepak and/or Dylos monitors provided real-time feedback, and passive nicotine monitors were used to measure...
1.1 Air pollution: A global overview In the last decades we witnessed unprecedented rapid deterioration in the environment as a consequence of intense anthropogenic activity. Air pollution, and more precisely particulate matter (PM) is both an alarming environmental problem and a public health concern that affects many regions of the world. Ambient air pollution has been associated with increas...
urbanization expanse and population growth, as well as pilgrim's possibility of some cities provide overuse of vehicles and consequently increased air pollution. thus by considering the importance of the impact of air pollution on human health, in this study, air pollution in terms of pm10 using psi standard index and inverse distance weighting is zoned in mashhad. on the other hand, meteo...
Use of biomass fuel in households is not a risk factor for pulmonary tuberculosis in South Ethiopia.
SETTING Rural settings of Sidama Zone in southern Ethiopia. OBJECTIVE To investigate the association between exposure to biomass fuel smoke and tuberculosis (TB). DESIGN A matched case control study in which cases were adult smear-positive pulmonary tuberculosis (PTB) patients on DOTS-based treatment at rural health institutions. Age-matched controls were recruited from the community. RES...
In the paper the problem of the real-time emission control is discussed, where the air quality forecast is based on the regional-scale model of air pollution transport. The problem formulation utilizes the optimal control technique for distributed parameter systems, which is integrated with the governing equations of air pollution dispersion process. The approach presented in the paper is sulfu...
Exposures to environmental pollution remain a major source of health risk throughout the world, though risks are generally higher in developing countries, where poverty, lack of investment in modern technology and weak environmental legislation combine to cause high pollution levels. Associations between environmental pollution and health outcome are, however, complex and often poorly character...
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...
