We assessed the influence of control for air pollution and respiratory epidemics on associations between apparent temperature (AT) and daily mortality in Mexico City and Monterrey. Poisson regressions were fit to mortality among all ages, children (ages 0-14 years) and the elderly (ages >or=65 years). Predictors included mean daily AT, season, day of week and public holidays for the base model....

Qiandao Lake (Xin’an Jiang reservoir) plays a significant role in drinking water supply for eastern China, and it is an attractive tourist destination. Three multivariate statistical methods were comprehensively applied to assess the spatial and temporal variations in water quality as well as potential pollution sources in Qiandao Lake. Data sets of nine parameters from 12 monitoring sites duri...

www.thoracic.org C LI P A N D C O P Y Where Does Outdoor Air Pollution Come From? Air pollution is the name for the mixture of harmful particles and gases in the air around us that we breathe. Air pollution is produced by both human activity and naturally occurring events. Burning of fossil fuels by motor vehicles (including cars, buses and trucks) and power plants (including coal-fired and nat...

this study proposes a method employing thermogravimetric analysis (tg) to predict pollutionlevels by heavy metals (cr, cu, ni, zn, pb, cd and hg) in port sediments close to urban and industrial sitesfrom bay of cádiz. for this purpose, the thermogravimetric results of 14 sediment samples were recorded andshowed two characteristic ranges of temperatures (w1 as weight loss, %: 200-650°c) vs. (w2 ...

BACKGROUND Meteorological conditions and air pollution in urban environments have been associated with general population and elderly mortality, showing seasonal variation. OBJECTIVES This study is designed to evaluate the relationship between apparent temperature (AT) and air pollution (PM₂.₅) vs. mortality in elderly population of Metro Vancouver. METHODS Statistical analyses are performe...

BACKGROUND We conducted a meta-analysis to evaluate the association between traffic-related air pollution and lung cancer in order to provide evidence for control of traffic-related air pollution. METHODS Several databases were searched for relevant studies up to December 2013. The quality of articles obtained was evaluated by the Strengthening the Reporting of Observational Studies in Epidem...

We compared heavy metal levels, calcium levels, breeding parameters and condition of nestling and adult Cyanistes caeruleus and Parus major along a heavy metal pollution gradient. Both species started laying earlier and showed inferior nestling growth and smaller fledging probability in the polluted areas, which are phenologically advanced in spring due to sparse forests. The major inter-specif...

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...

Exposure to elevated air pollution levels can aggravate pollen allergy symptoms. The aim of this study was to investigate the relationships between airborne birch (Betula) pollen, urban air pollutants NO2, O3 and PM10 and their effects on antihistamine demand in Gothenburg and Malmö, Sweden, 2006-2012. Further, the influence of large-scale weather pattern on pollen-/pollution-related risk, usin...
