“…These results were in agreement with those reported by Suk and Nam [ 4 ] regarding the pollen season of weeds (August–October) at Gyeongsan in 2004, but not of trees (March–June) and grasses (May–October), which started a month later than observed in the present study. Our findings were also in agreement with the nationwide (including Seoul) pollen season of trees and weeds [ 13 ]; however, the pollen season of grasses could not be compared, since no data have been reported previously.…”

“…Airborne pollen collected from Incheon and Seoul in 2015 and 2016 comprised 32 families and 50 genera, showing a higher diversity than that reported by Sung et al [ 17 ] (19 species in 1998–2012) and that reported by Park et al [ 13 ] (15 tree species and 8 weed species in 1997–2007). The present study included all the 16 major pollen types reported in previous studies [ 13 ], which were carried out in 7 major regions of South Korea, as well as Chenopodiaceae, which is also an allergenic pollen type. Although weed and grass pollen concentrations are lower than tree pollen concentrations, an accurate classification is essential, since allergenicity varies among plants [ 18 ].…”

“…(47,621 grains/m 3 , 15.3%) among the herbaceous species. These 2 genera also showed the highest pollen concentrations in previous studies carried out in Korea, [ 13 17 19 ]; however, no quantitative comparisons could be made, since the previous studies presented only percentages and not pollen concentrations. In contrary, our findings were not in agreement with those reported by Suk and Nam [ 4 ] and Oh et al [ 10 ], in which Artemisia spp.…”

“…Since the investigation of airborne pollen distributions is essential for the diagnosis and treatment of allergic diseases, multiple surveys and studies have been performed in the United States, Europe, and Japan [ 6 7 8 ]. Several studies have also carried out in South Korea to investigate the association of airborne pollen and climate with allergic diseases [ 9 10 11 12 13 14 15 16 ].…”

BackgroundPollen allergens are one of the main contributors to the development and/or aggravation of allergic rhinitis, allergic conjunctivitis, and asthma.ObjectiveAn examination of the airborne pollen in residential areas should be conducted to aid the diagnosis and treatment of allergic diseases.MethodsAirborne pollen samples were collected from 2 sites in Incheon and 2 in Seoul from 2015 to 2016.ResultsThe highest monthly concentration of airborne pollen was observed in May and September each year. Pollen from 32 families and 50 genera was identified over the 2 years; of these, Pinus spp. showed the highest pollen concentration (41.6%), followed by Quercus spp. (25.3%), and Humulus spp. (15.3%), the latter of which had the highest concentration among weed pollen. The total pollen concentration was significantly higher in Incheon than in Seoul (p = 0.001 in 2015, p < 0.001 in 2016) and higher in 2016 than in 2015. The concentrations of pollen from weed species (Cupressaceae, Humulus spp., Artemisia spp., Ambrosia spp., and Chenopodiaceae) and grass species (Gramineae) were significantly higher (p < 0.001) than those from tree species. Pollen was distributed from February to November. The first pollen identified in both regions in each year was Alnus spp. Overall, the total concentration of Quercus spp., Betula spp., Humulus spp., Artemisia spp., Ambrosia spp., and Chenopodiaceae pollen increased significantly over the 2 years.ConclusionRegion-specific differences exist in the pollen of major allergenic plants. Continuous monitoring of pollen is thus essential for management of pollen-related allergic disorders in each region.

“…However, because this calendar was based on the mean concentration of pollen nationwide, it did not reflect the regional characteristics of pollens and may be inaccurate due to recent changes in the climate. Therefore, it was necessary to develop a new calendar that included the geographic and monthly distribution of pollens and included data obtained after 2004 25. The old calendars were also modified by deleting data that did not match the dates of pollen distribution as reported in previous research.…”

The old calendar of pollens did not reflect current pollen distribution and concentrations that can be influenced by changes of weather and environment of each region in South Korea. A new pollen calendar of allergenic pollens was made based on the data on pollen concentrations obtained in eight regions nationwide between 1997 and 2009. The distribution of pollen was assessed every day at 8 areas (Seoul, Guri, Busan, Daegu, Jeonju, Kwangju, Kangneung, and Jeju) for 12 years between July 1, 1997 and June 30, 2009. Pollens were collected by using Burkard 7-day sampler (Burkard Manufacturing Co Ltd, UK). Pollens which were stained with Calberla's fuchsin staining solution were identified and counted. Pine became the highest pollen in May, and the pollen concentrations of oak and birch also became high. Ragweed appeared in the middle of August and showed the highest pollen concentration in the middles of September. Japanese hop showed a high concentration between the middle of August and the end of September, and mugwort appeared in the middles of August and its concentration increased up until early September. In Kangneung, birch appeared earlier, pine showed a higher pollen concentration than in the other areas. In Daegu, Oriental thuja and alder produced a large concentration of pollens. Pine produced a large concentration of pollens between the middle of April and the end of May. Weeds showed higher concentrations in September and mugwort appeared earlier than ragweed. In Busan the time of flowering is relatively early, and alder and Oriental thuja appeared earliest among all areas. In Kwangju, Oriental thuja and hazelnut appeared in early February. Japanese cedar showed the highest pollen concentration in March in Jeju. In conclusion, update information on pollen calendar in South Korea should be provided for allergic patients through the website to manage and prevent the pollinosis.

A biology-driven receptor model for daily pollen allergy risk in Korea based on Weibull probability density function

Pollen is an important cause of respiratory allergic reactions. As individual sanitation has improved, allergy risk has increased, and this trend is expected to continue due to climate change. Atmospheric pollen concentration is highly influenced by weather conditions. Regression analysis and modeling of the relationships between airborne pollen concentrations and weather conditions were performed to analyze and forecast pollen conditions. Traditionally, daily pollen concentration has been estimated using regression models that describe the relationships between observed pollen concentrations and weather conditions. These models were able to forecast daily concentrations at the sites of observation, but lacked broader spatial applicability beyond those sites. To overcome this limitation, an integrated modeling scheme was developed that is designed to represent the underlying processes of pollen production and distribution. A maximum potential for airborne pollen is first determined using the Weibull probability density function. Then, daily pollen concentration is estimated using multiple regression models. Daily risk grade levels are determined based on the risk criteria used in Korea. The mean percentages of agreement between the observed and estimated levels were 81.4-88.2 % and 92.5-98.5 % for oak and Japanese hop pollens, respectively. The new models estimated daily pollen risk more accurately than the original statistical models because of the newly integrated biological response curves. Although they overestimated seasonal mean concentration, they did not simulate all of the peak concentrations. This issue would be resolved by adding more variables that affect the prevalence and internal maturity of pollens.
