WHO/Europe's software tool AirQ+ performs calculations that allow quantification of the health effects of exposure to air pollution, including estimates of the reduction in life expectancy. the effects of short-term changes in air pollution (based on risk estimates from time-series studies); the effects of long-term exposures (using life-tables An exposure assessment estimates how much of a pollutant people inhale during a specific time period, as well as how many people are exposed. There are many sources of toxic air pollutants. For example, a factory smokestack or thousands of automobiles crossing a busy intersection each day could be the source of a pollutant of concern. So the first step in an exposure assessment is to decide Internship | Air pollution exposure assessment. Utrecht, Utrecht 6 mois . Offre pourvue . Air pollution is a global problem resulting in 4.2 million premature deaths in 2016 (WHO factsheet) and costs an estimated 8.1 trillion USD in 2019 equivalent to 6.1% of global GDP (Worldbank). Pollution levels increase 8% per year. The latest burden estimates reflect the very significant role air Here advances in air pollution exposure assessment and their applications to studies of respiratory disease are reviewed, with a focus on recent studies of traffic-related air pollution and asthma. Although continuous measurements of personal exposures for all study subjects for a complete study period might be considered the desired "gold standard" for exposure, this is rarely, if ever Air pollution exposure is a global health concern: some 90% of the world's population is breathing outdoor air that falls below the World Health Organization (WHO) air quality guidelines 36.In Study: Long-term air pollution exposure and COVID-19 case-severity:An analysis of individual-level data from Switzerland. Image Credit: Lemberg Vector studio/Shutterstock Background. Multiple Although laboratory studies, both human and animal, have contributed to both hazard identification and risk assessment of air pollution (especially for certain carcinogenic substances), epidemiologic studies provide a rich source of information for impact assessment of the most common exposures and are a preferable basis for impact assessment. Here, we addressed how exposure assessment influences the size of estimated effects for adverse pregnancy outcomes when traffic-related air pollution is modeled by four commonly-used methods. Based on these four measures, results were consistent in suggesting that pregnant women who experience higher exposure to traffic-related pollutants were more likely to develop preeclampsia during pregnancy or to give birth to preterm and very preterm infants. For preeclampsia, gaseous air pollutants Download (5.4 MB) Overview This report presents a summary of methods and results of the latest WHO global assessment of ambient air pollution exposure and the resulting burden of disease. Air pollution has become a growing concern in the past few years, with an increasing number of acute air pollution episodes in many cities worldwide. Air
