“…In urban areas, common ragweed, for example, grows faster, flowers earlier and produces more pollen (Ziska et al 2003). A prolonged and intensified pollen season caused by climate change affects allergy sufferers and might increase the probability of developing new allergies (D'Amato et al 2014).…”

“…Due to an increase in greenhouse gas emissions, especially anthropogenic carbon dioxide (CO 2 ), global warming has intensified over the past decades (D'Amato et al 2014). Cities might be seen as ''harbingers of climate change'' because urban CO 2 and temperature levels are already higher than in rural areas (Ziska et al 2003).…”

In this study, the seasonally averaged intradiurnal patterns of four different pollen types (Fraxinus, Betula, Poaceae and Artemisia) and the role of traffic volume, air pollution and selected weather parameters were investigated. Measurements were carried out with a 7-day recording volumetric spore trap (Hirst type) near a congested city motorway (the A 100) in Berlin, Germany, in 2012, 2013 and partly 2011. Both Poaceae and Artemisia pollen showed distinct patterns which were similar across the years. The main period of grass pollen concentrations in the air was from 8 a.m. to 10 p.m. with peaks about midday or in the afternoon. Mugwort pollen mainly occurred between 6 a.m. and 2 p.m. with a clear maximum from 8 to 10 a.m. With regard to Fraxinus and Betula pollen, the patterns were not as clear and showed differences throughout the years. The intradiurnal patterns of traffic volume and pollen load, mainly of Poaceae in the afternoon and Artemisia in the morning, were partly coincident. The combination of both a high pollen count and air pollution, due to exhaust emissions, represents a special health threat which could result in a double burden for allergy sufferers. In the case of the daily means of Betula and Poaceae, relative humidity had a significantly negative effect on pollen concentrations on the same and/or next day/s, sunshine duration (Poaceae) and air temperature (Artemisia) a positive one.

“…Interestingly, migrant children had higher rates of asthma compared to their parents, highlighting the critical role of early-life environmental factors in the pathogenesis of allergic disorders. Other studies have also demonstrated correlations between urbanization and high levels of vehicle emissions with increases in pollen-induced respiratory allergy in urban compared to rural populations [33]. …”

“…Global warming has resulted in longer pollen seasons, changes in crop patterns, and pollen distribution patterns [33]. Environmental conditions specific to urban regions such as high nocturnal temperatures, increased atmospheric carbon dioxide, and nitrogen deposition provide favourable conditions for agriculture, leading to increased production of pollen and airborne allergenic protein loads [51-54].…”

Studies in migrant populations provide vital opportunities to investigate the role of environmental factors in the pathogenesis of allergic disorders. Differences in allergy prevalence have been observed between migrants and native-born subjects living in the same geographical location. Immigrants who migrate from less affluent countries with lower allergy prevalence tend to have a lower prevalence of allergic disorders compared to native-born residents of the more affluent host country. The patterns of allergic disease prevalence also differ between first- and second-generation migrants. The timing of migration in relation to birth, age at migration, and duration of residence in the host country also influence one’s atopic risk. A complex interplay of multiple environmental, socioeconomic, and cultural factors is likely responsible for these observed differences. Further research into the roles of various risk factors in modulating differences in allergic disease prevalence between migrant and native populations will enhance our understanding of the complex gene-environment interactions involved in the pathogenesis of allergic disorders.

Background Grass pollen is the most prevalent sensitizing aeroallergen to cause respiratory allergies in northern China. Air pollutants have a substantial effect on respiratory health and some pollens. This study aimed to investigate relationships among airborne grass pollen, air pollutants and allergic diseases, in order to determine their effects on patients with grass pollen allergies in Beijing, China, during the period from 2013 to 2016. Methods Data regarding autumnal grass pollens and air pollutants measured in Beijing from 2012 to 2016 were obtained from local governmental agencies. Patient data regarding specific immunoglobulin E (IgE) analyses from 2013 to 2016 were obtained from the Department of Allergy in Beijing Tongren Hospital. Spearman's rank correlation analysis was used to assess associations between the daily number of grass pollen allergen–positive patients and the following parameters: 3 clinically‐relevant grass pollen genera (Artemisia, Humulus, and Chenopodium) and inhalable pollutants. Results Correlation analysis indicated that the daily number of grass pollen‐positive patients was significantly associated with the peak period of grass pollens, as well as pollutants SO2 and NOx. Moreover, concentrations of air pollutants (eg, ozone, oxides of nitrogen [NOx], and SO2) were consistently and significantly associated with concentrations of grass pollens; particulate matter 2.5 µm in diameter was negatively associated with Artemisia and Chenopodium pollens. Conclusion Grass pollens exhibited substantial impact on allergic disease morbidity. Air pollutants impacted allergic disease and grass pollen. Thus, public health and clinical approaches to anticipate and reduce allergic disease morbidity from pollen and pollutants are needed.
