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.

Vehicular traffic adds up different kinds of contaminants like heavy metals, polyaromatic hydrocarbons, gaseous toxins etc. to the atmosphere. Pollen grains of different plants have been found to be sensitive to these pollutants, which show varied effects on their viability, and size and hence can be used as bioindicators of air pollution. Keeping this in mind, the present work was designed to measure the pollen viability and pollen size of three common roadside plants, namely Alstonia scholaris, Nerium oleander and Tabernaemontana divaricata belonging to Apocynaceae family growing at seven sites of Amritsar city with varying levels of traffic stress. Pollen viability and pollen size were studied using 2, 3, 5-triphenyl tetrazolium chloride (TTC) staining method. The percentage of pollen viability of A. scholaris ranged from 32.45% to 65.74%, for N. oleander it ranged from 30.3% to 45.11% and for T. divaricata it ranged from 14.31% to 49.62%. Pollen size ranged from 22.86 to 23.94 µm for A. scholaris, 29.58 to 32.17 µm for N. oleander and 29.83-32.43 µm for T. divaricata. Pollen viability was found to be inversely proportional to a load of traffic at a given site whereas no remarkable variation was found in pollen size. For A. scholaris, a significant negative correlation (r= -0.762, p≤0.05) was observed between pollen viability and traffic load, while for other two species correlation between pollen viability and traffic load was not statistically significant at p≤0.05.

“…Negative environmental stress strongly influences pollen grains, what is however not always mirrored in their morphology. It affects the pollen viability, germination, and finally reproduction success of the plant (Malayeri et al 2012; Buta et al 2015; Lahlali et al 2014). Kaur et al (2015) stated that the size and morphology does not depend on traffic, which yet, affects pollen viability.…”

Nowadays, pollen allergy becomes an increasing problem for human population. Common mugwort (Artemisia vulgaris L.) is one of the major allergenic plants in Europe. In this study, the influence of air pollution caused by traffic on the structure and chemical composition of common mugwort pollen was investigated. Scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), and curve-fitting analysis of amide I profile was applied to assess the morphological and structural changes of mugwort pollen grains collected from sites with different vehicle pollution levels. Microscopic observations support the conclusion, that the higher the car traffic, the smaller the pollen grains. The obtained results clearly show that air pollution had an impact on different maximum absorbance values of individual functional groups composing the chemical structure of pollen. Moreover, air pollution induced structural changes in macromolecules of mugwort pollen. In pollen collected from the unpolluted site, the content of sporopollenin (850 cm−1) was the highest, whereas polysaccharide concentration (1032 cm−1) was the lowest. Significant differences were observed in lipids. Pollen collected from the site with heavy traffic had the lowest content of lipids at 1709, 2071, and 2930 cm−1. The largest differences were observed in the spectra regions corresponding to proteins. In pollen collected from unpolluted site, the highest level of β-sheet (1600 cm−1) and α-helix (1650 cm−1) was detected. The structural changes in proteins, observed in the second derivative of the FTIR spectrum and in the curve-fitting analysis of amide I profile, could be caused inter alia by air pollutants. Alterations in protein structure and in their content in the pollen may increase the sensitization and subsequent risk of allergy in predisposed people. The obtained results suggest that the changes in chemical composition of pollen may be a good indicator of air quality and that FTIR may be successfully applied in biomonitoring.
