“…69 Outdoor levels of PM 10 and PM 2.5 have been related to acute reductions in FEV 1 and FVC, observed either within the same day, a few hours after exposure, or days after exposure (lag response). [70][71][72] In contrast, recent pooled analyses of cross-sectional studies in 12 countries did not reveal any association between PM 10 exposure and lung function in children. 73 Understanding the chronic respiratory health effects of outdoor air pollutants is more complex.…”

“…All, except two, studies investigated school-aged asthmatic and/or symptomatic children, while the remaining two considered infants and toddlers (Andersen et al 2008b;Coneus & Spiess, 2012). Most of the studies observed positive associations between short-term exposure to NO 2 (or nitrogen oxides) for different lags and respiratory symptoms, such as coughing and wheezing (O'Connor et al, 2008;Escamilla-Nuñez et al, 2008;Andersen et al, 2008b), as well as for exhaled nitric oxide (Sarnat et al, 2012) and also for pulmonary function decrease (O'Connor et al, 2008;Liu et al, 2009;Castro et al, 2009;Dales et al 2009;Min et al, 2008;Yamazaki et al, 2011;Ma et al, 2008) in children, although not all of them were statistically significant (Dales et al, 2009).

This document presents answers to 24 questions relevant to reviewing European policies on air pollution and to addressing health aspects of these policies. The answers were developed by a large group of scientists engaged in the WHO project "Review of evidence on health aspects of air pollution -REVIHAAP". The experts reviewed and discussed the newly accumulated scientific evidence on the adverse effects on health of air pollution, formulating science-based answers to the 24 questions. Extensive rationales for the answers, including the list of key references, are provided. The review concludes that a considerable amount of new scientific information on the adverse effects on health of particulate matter, ozone and nitrogen dioxide, observed at levels commonly present in Europe, has been published in recent years. This new evidence supports the scientific conclusions of the WHO air quality guidelines, last updated in 2005, and indicates that the effects in some cases occur at air pollution concentrations lower than those serving to establish these guidelines. It also provides scientific arguments for taking decisive actions to improve air quality and reduce the burden of disease associated with air pollution in Europe.This publication arises from the project REVIHAAP and has been co-funded by the European Union.

“…This weak association supports our findings, where we adjusted rigorously for potential confounders (e.g., living district, asthma status of the child), and found only associations of FVC and FEV 1 one year before the lung function measurement within the overall population. For the lagging effect of PM on lung function, the analysis was done by reviewing previous studies and found that more attention had been paid to the short-term acute effect (54,55), while fewer studies on the long-term effect can be referred to. Our study suggests that ADD may be used in future studies addressing the effects of long-term air pollution exposure.…”

Background: The current literature is still not consist regarding the effect of long-term exposure to PM2.5 and children's lung function, partly due to inadequate or inaccurate exposure assessment. In this study, we aim to investigate the associations between long-term exposure to PM2.5, estimated as average daily dose (ADD), and lung function in school-age children. Methods: We recruited 684 participants of 7-12 years old from the city of Lanzhou located in northwestern China. Participants underwent spirometric tests for lung function and responded to a questionnaire survey.Detailed information about individual air exposure and personal information were collected, including length of school hours, home address, age, gender, etc. Combining the spatial distribution of PM2.5 concentrations in the past 5 years and individual time-activity data, we estimated annual ADD for 5 years preceding the lung function tests and 5-year average ADD, respectively. We used multiple linear regression models to examine the associations between ADD values and lung function, controlling for a range of individual-level covariates. Results: The 5-year average ADD among all the participants was 50.5 μg/kg-d, with higher values estimated for children living in the urban area than the suburban area, for boys than girls, and for children whose parents received a lower education attainment. We found that a 1 μg/kg-d increment in ADD of PM2.5 was associated with a 10.49 mL (95% CI: −20.47, −0.50) decrease in forced vital capacity (FVC) and a 7.68 mL (95% CI: −15.80, −0.44) decrease in forced exploratory volume in 1 second (FEV 1 ). Among the annual ADDs estimated for the preceding 5 years, the immediate past year prior to lung function measurement had the greatest effect on lung function. The effect was greater in girls than in boys. We found no associations between annual exposure of PM2.5 (instead of ADD) and lung function when defined concentration was used as an exposure variable. Conclusions: Long-term PM2.5 exposure, when estimated as exposure dose averaged over a year or longer, was associated with statistically significant reductions in FVC and FEV1 in children of elementaryschool age. Future studies may consider the use of individual-level dose estimates (as opposed to exposure concentrations) to improve the dose-response assessment.
