OBJECTIVE To assess the effects of air pollution levels on respiratory morbidity among children from 1999 to 2000. METHODS Daily records of health center attendance due to respiratory diseases among children were obtained from the public health system in Curitiba, State of Paraná, Brazil. Daily levels of particulate matter (PM10), smoke, NO2 and O3 were obtained from both Paraná State Environ...

BACKGROUND The health effects caused by electronic cigarette (e-cigarette) use are not well understood. OBJECTIVE Our purpose was to document the positive and negative short-term health effects produced by e-cigarette use through an analysis of original posts from three online e-cigarettes forums. METHODS Data were collected into Microsoft Access databases and analyzed using Cytoscape assoc...

BACKGROUND Wildfire activity is predicted to increase in many parts of the world due to changes in temperature and precipitation patterns from global climate change. Wildfire smoke contains numerous hazardous air pollutants and many studies have documented population health effects from this exposure. OBJECTIVES We aimed to assess the evidence of health effects from exposure to wildfire smoke...

Much of the world population, particularly in developing countries, still relies on firewood to meet basic energy needs. The resulting indoor air pollution can have severe health consequences, particularly for young children who spend considerable time in close proximity to the fire while their mothers cook. In this paper we use data from a household survey to examine gas stove adoption, firewo...

Household air pollution (HAP) can influence adult respiratory health. More prospective studies are needed, taking into account combined effects and patterns of HAP exposure, gene-environment interactions.https://bit.ly/3lXc3g7

background: considering health and public health risks, particulate matters are the main pollutants of air and are associated with high rates of mortality and morbidity in long and short term exposures. hence, the present study was performed with the aim of estimating the health impacts attributable to pm10 in the 7 cities of mashhad, tabriz, isfahan, shiraz, arak, ahwaz, and urmia (iran) durin...

OBJECTIVES The PEACE study is a multicentre panel study of the acute effects of particles with a 50% cut off aerodynamic diameter of 10 microns (PM10), black smoke (BS), sulphur dioxide (SO2), and nitrogen dioxide (NO2) on respiratory health of children with chronic respiratory symptoms. In the complete panels no consistent association between air pollution and respiratory health was found. The...
