“…However, Ward et al contradicted this fact in his work [8]. Yet, Yamazaki et al seems to confirm Van der Zee's thesis [16]. Nevertheless, the absence of statistically significant influence of particulate matter and CO concentration on healthy adults' PEFR, as shown in our work has been confirmed by numerous authors [17].…”

Introduction. Peak Expiratory Flow Rate (PEFR) was first described by Hadorn as a measure of the lung function. The definition of PEFR established by the European Respiratory Society defines it as the maximal flow achieved during the phase of expiration, delivered with maximal force and starting from the maximal lung inflation level.Aim. The authors of this study attempted at evaluating the variations of PEFR, taking into consideration the effects of one's age, height Body Mass Index (BMI), Body Surface Area (BSA), seasons of the year and air pollution. Healthy adults living in urban areas were subjects of the study.Material and methods. The study group consisted of some 179 healthy subjects, 102 women and 77 men, aged 18 to 66. Every patient's medical history, including epidemiological, demographic data, as well as the information about the occurrence and symptoms of lung diseases, was taken from every patient. Only healthy subjects were selected for further analysis. Participants performed spirometry testing. Physical parameters were measured. Appropriate pollution data was obtained.Results. The study group consisted of 179 patients (102 women and 77 men). There is a negative correlation between PEFR and age and a positive one between PEFR and height, as well as Body Surface Area and BMI (regarded as a quantitative, but not as a qualitative trait). There is a significant correlation between PEFR and PEFR adjusted by age, height and weight with seasons of the year. There is a statistically significant negative impact of NO 2 , SO 2 and O 3 24 h mean and hourly NO 2 concentration on PEFR.Conclusions. Peak Expiratory Flow Rate changes are also present in a healthy adult population. Prevalence of obesity is an important factor of the examined population.

“…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.

“…Additionally, Japanese epidemiological studies have shown associations between air pollutants and asthma prevalence [15][16][17][18]. Yamazaki et al, [19,20] found that the odds ratio (OR) in warmer months per 10 ppb increment in 24-hr mean concentration of surface ozone was 1.25 (95% Confidence Interval (CI): 0.87-1.82), and the association between ozone concentrations and asthma admissions for the preschool age group (2-5 years) was stronger than the age group of 6-14 years. Also rice crop, which is the main crop in Japan, is likely to be affected by surface ozone as it can be estimated easily based on AOT40 index (accumulated exposure over a threshold of 40 ppb calculated for three months during the growing season) [7].…”

Despite low concentrations of aerosols and precursors of surface ozone in Japan compared with other countries in East Asia, concentrations of surface ozone there are yearly increasing and endangering the environment. The aim of this study was to examine whether transboundary air pollution from neighboring countries such as China could be associated with this increase or not. Data on the 1-hr daytime and maximum-hr concentrations of surface ozone were obtained from 1,183 monitors distributed in 47 prefectures. Annual means of these concentrations were calculated for all districts that are located along the Sea of Japan since these districts are the first receptors of transboundary air pollution from neighboring countries. We found that the annual mean of the 1-hr daytime and maximum-hr concentrations of surface ozone are positively associated with the annual increase of the industrial waste gas emissions in China from 2000 to 2009. This finding suggests that the industrial emissions from China could be associated with the annual increase surface ozone concentrations in Japan. However, limited spatiotemporal information about the emissions of surface ozone and its precursors in China makes it hard to quantify the contribution percentage.
