“…Daily SO 2 and NO 2 concentrations had clear seasonality, with peak concentrations occurring during the winter. Daily patterns for the concentrations of SO 2 and NO 2 in this study were consistent with previous studies (Zhang et al 2011a;Zhang et al 2011c). The pollutant concentrations were typically higher during the winter from November to the following March (Zhang et al 2011c).…”

To investigate temporal patterns, pollution concentrations and the health effects of air pollutants in Beijing we carried out time-series analyses on daily concentrations of ambient air pollutants and daily numbers of outpatient visits for otolaryngology over 2 years (2011)(2012) to identify possible health effects of air pollutants. The results showed that PM 10 was the major air pollutant in Beijing and that air quality was slightly better in 2012 than in 2011. Seasonal differences were apparent for SO 2 and NO 2 . Both the background and urban areas of Beijing experienced particulate matter pollution in 2011. In addition to local air pollution, Beijing was also affected by pollutants transported from other regions, especially during heavy air pollution episodes. PM 10 , NO 2 , and SO 2 concentrations showed positive associations with numbers of outpatient visits for otolaryngology during winter. NO 2 and SO 2 also had adverse ear, nose, and throat health effects outside of winter. The ear, nose, and throat health risks caused by air pollutants were higher during the winter than during the summer. NO 2 had stronger influence on increased the likelihood of outpatient visits than SO 2 . The findings provide additional information about air quality and health effects of air pollution in Beijing.

“…In the period January 14 -July 14, total pollen excluding Ambrosia pollen indicates very low weights for each category involving an indifferent role in severe asthma attacks (Table 2c). Results received for the period July 15 -October 16 (Table 2a) indicating significant positive associations between pollen levels and the patient numbers, are similar to those found [77,81,82].…”

“…For example, high levels of NO 2 partly indicate no significant association with respiratory admissions [30] and partly increase the susceptibility for respiratory diseases [60]. Other examples of the significant positive impact of NO2 levels on respiratory causes are given [49,61,62,64,72,73,77]. Climate and NO 2 dependence of respiratory diseases is also stressed.…”

Joint effect of biological (pollen) and chemical air pollutants on asthma emergency room (ER) visits was analyzed for Szeged region of Southern Hungary. Our database of a nine-year period (1999)(2000)(2001)(2002)(2003)(2004)(2005)(2006)(2007) includes daily number of asthma emergency room (ER) visits, and daily mean concentrations of CO, PM 10 , NO, NO 2 , O 3 and SO 2 , furthermore two pollen variables (Ambrosia and total pollen excluding Ambrosia), as well. The analysis was performed for ER visits of asthma bronchiale using two age groups (adults and the elderly) of males and females for three seasons. Factor analysis was performed in order to clarify the relative importance of the pollutant variables affecting asthma ER visits. Asthma ER visits denote notably stronger associations with the pollutants in adult male than in adult female patients both for the pollen season of Ambrosia and the pollen-free season. Furthermore, adults are substantially more sensitive to severe asthma attack than the elderly for the season of total pollen excluding Ambrosia pollen. The joint effect of the chemical and pollen variables is the highest for the asthma ER cases in the pollen season of Ambrosia, basically due to the extra impact of the total pollen excluding Ambrosia pollen and partly due to Ambrosia pollen. A nonparametric regression technique was applied to discriminate between events of ER visit -no ER visit using pollen and chemical pollutants as explaining variables. Based on multiple correlations, the strongest relationships between ER visits and pollutants are observed during the pollen-free season. The elderly group with asthma bronchiale is characterized by weaker relationships between ER visits and pollutants compared to adults. Ratio of the number of correct decisions on the events of ER visit -no ER visit is lowest for the season of total pollen excluding Ambrosia pollen. Otherwise, similar conclusions hold as those received by multiple correlations. on aeroallergens. These include impacts on pollen amount, pollen allergen city, pollen season, plant and pollen distribution, and other plant attributes [18][19][20][21][22]. Hence, due to the continually increasing air pollution, respiratory diseases are of major concern worldwide. Air pollution of Hungary is one of the highest in Europe. Around 16,000 annual premature deaths attributable to exposure to ambient PM 10 concentrations are estimated in the country [23,24]. Furthermore, airborne pollen levels are also high. The Carpathian basin, involving Hungary (Figure 1) is considered the most polluted region with airborne ragweed (Ambrosia) pollen in Europe. Ambrosia in Hungary discharges the most pollen of all taxa; the ratio of its pollen release compared to the total pollen release in the late summer period is around 60-71% [25]. Highest counts on peak days in Szeged, Southern Hungary, are about one order of magnitude higher than those in other cities of Europe [26]. The sensitivity of patients to ragweed in Szeged is 83.7% [27]. About 30% of the Hungar...

“…These diseases are prevalent in China, where air pollution levels are often orders of magnitude higher than those in developed countries (Zhang et al, 2011). Because PM deposition and related health effects depend on the particle size, PM 2.5 (fine particles with aerodynamic diameter ≤ 2.5 µm) and ultrafine particles (UFP; diameter < 100 nm) have been associated more strongly with health risk than PM 10 (Politis et al, 2008).…”

Developing countries, such as China, are facing serious air pollution issues due to fast economic development. In this study, traffic related air pollutants, including number concentration of ultrafine particles (UFPs, diameter < 100 nm), mass concentrations of PM 2.5 and black carbon (BC) were measured near the Peking University (PKU) campus in Beijing in December 2011. Data were collected concurrently at a roadway site and on PKU campus. Meteorological data were collected at approximately 40 meters northeast from the roadway sampling site. The traffic density was determined from recorded video footage. Roadside UFP and PM 2.5 concentrations were not significantly higher than on campus. A statistically significant Pearson's correlation of 0.75 was found between BC and PM 2.5 mass concentrations. No apparent correlation was found between wind speed and UFP number concentrations, but strong log-decay correlations were found between wind speed and PM 2.5 (R 2 = 0.80). There were three days during the measurements when both PM 2.5 mass concentrations and UFP number concentrations were higher at the campus site than at the roadway site. This suggests there were potential local emission sources on campus. Temporal profile of UFPs at the campus site peaked around lunch and dinner time, suggesting emissions from the surrounding restaurants and cafeteria that used Chinese-style cooking might have contributed to the observed PM 2.5 and UFP levels on campus.
