“…[6][7][8][9] Several studies have reported that dust particles and anthropogenic air pollutants have been transported by the prevailing westerlies and winter monsoon from mainland East Asia to leeward areas, including Taiwan, Korea, and Japan. [10][11][12] We examined air pollutants containing mutagens and other chemicals in western Japan, namely, Dazaifu in Fukuoka Prefecture and Yurihama in Tottori Prefecture, for one year. Highly mutagenic airborne particles were collected at both sites in January and February 2013.…”

Public concern regarding the transport of air pollutants from mainland East Asia to the leeward area by the prevailing westerlies in spring and winter monsoon has been growing in recent years. We collected total suspended particle (TSP) in Beijing, a metropolis of China located windward of Japan, in spring (late February 2011-May 2011) and in winter (November 2012-early February 2013), then analyzed metals, ions, and organic compounds and mutagenicity, and compared the pollution levels with samples collected at two Japanese metropolises (Osaka and Nagoya) during the same periods. The medians of concentration of TSP and other factors in Beijing were much larger than those in the Japanese metropolises. Especially, the concentrations of polycyclic aromatic hydrocarbons (PAHs) were remarkably high in Beijing in winter, and the median of total PAHs concentration in Beijing was 62-63 times larger than that in the Japanese sites. The mutagenicity of TSP from Beijing toward Salmonella typhimurium YG1024, with and without a mammalian metabolic system (S9 mix), was 13-25 times higher than that from the Japanese sites in winter. These results suggest that air pollution levels in Beijing are very high compared with those at the two Japanese metropolises we evaluated. The diagnostic ratios of PAHs and nitrated polycyclic aromatic hydrocarbons (NPAHs) suggest that the major sources of PAHs and NPAHs in Beijing are different from those at the two Japanese sites in winter, and that the major source in Beijing is coal/biomass combustion.

“…In addition to anthropogenic air pollutants, a natural phenomenon known as Asian sand dust (ASD) causes air pollution in East Asia. ASD particles originating from inland China, including the Gobi and Taklamakan deserts and the Loess Plateau, are transported to East Asia with the westerlies and monsoon mainly in the spring, accompanied by pollutants produced in industrial areas on the east coast of China [ 6 , 7 ]. Ambient nitrate and sulfate concentrations have been reported to remain high, accompanied by long-lasting high ambient particulate matter (PM) concentrations, during ASD events in Korea and Japan [ 8 ].…”

ObjectivesAir pollution is a growing concern in Korea because of transboundary air pollution from mainland China. A panel study was conducted to clarify the effects of air pollution on respiratory symptoms and health-related quality of life (HR-QoL) in outpatients with and without chronic obstructive pulmonary disease (COPD) in Korea.MethodsPatients filled out a questionnaire including self-reported HR-QoL in February and were followed up in May and July. The study was conducted from 2013 to 2015, with different participants each year. Air quality parameters were applied in a generalized estimating equation as independent variables to predict factors affecting HR-QoL.ResultsLower physical fitness scores were associated with Asian sand dust events. Daily activity scores were worse when there were high concentrations of particulate matter (PM) less than 10 μm in diameter (PM10). Lower social functioning scores were associated with high PM less than 2.5 μm in diameter and nitrogen dioxide (NO2) concentrations. High NO2 concentrations also showed a significant association with mental health scores. Weather-related cough was prevalent when PM10, NO2, or ozone (O3) concentrations were high, regardless of COPD severity. High PM10 concentrations were associated with worsened wheezing, particularly in COPD patients.ConclusionsThe results suggest that PM, NO2, and O3 cause respiratory symptoms leading to HR-QoL deterioration. While some adverse effects of air pollution appeared to occur regardless of COPD, others occurred more often and more intensely in COPD patients. The public sector, therefore, needs to consider tailoring air pollution countermeasures to people with different conditions to minimize adverse health effects.

To clarify the seasonal fluctuations in air pollution and the effect of long-range transport, we collected airborne particles (n 118) at Dazaifu in Fukuoka, Japan, from June 2012 to May 2013 and measured Pb and SO 4 2 , which are indicators of the long-range transport of anthropogenic air pollutants, as well as their mutagenicity, and other factors. The levels of airborne particles, Pb, and SO 4 2 were very high on March 4, 8, 9, and 19, and May 13, 21, and 22, 2013. The backward trajectories indicated that air masses had arrived from the Gobi Desert and northern China on those days. The mutagenicity of airborne particles was examined using the Ames test on Salmonella typhimurium YG1024. Highly mutagenic airborne particles were mostly collected in winter, and most of them showed high activity both with and without S9 mix. High levels of polycyclic aromatic hydrocarbons (PAHs) were found in many samples that showed high mutagenicity. For the samples collected on January 30, February 21, and March 4, the levels of Pb, SO 4 2 , PAHs, and mutagenicity were high, and the backward trajectories indicated that air masses present on those days had passed through northern or central China. The Japan Meteorological Agency registered Asian dust events at Fukuoka on March 8, 9, and 19, 2013. The results of the present study suggest that high levels of anthropogenic air pollutants were transported with Asian dust. Similarly, long-range transport of air pollutants including mutagens occurred on days when Asian dust events were not registered.Key words transboundary air pollution; airborne particle; Asian dust; China; Ames test; mutagenicity Many epidemiological studies have indicated that ambient air pollution is associated with mortality from lung cancer and respiratory diseases, and others.
