As there are more and more people who take outdoor activities, pollinosis patients having bronchial asthma, allergic conjunctivitis, and allergic rhinitis are increasing. The pollen is produced by various plants. Especially, anemophilous pollen is mostly related to allergic diseases. In Korea, pollinosis is mainly caused by pollen from both trees in spring and weeds in fall, respectively. Oak, birch, and cedar are the main tree species generating allergenic pollen and ragweed, mugwort, and humulus are the main weed species.
National Institute of Meteorological Research (NIMR) and the Korean Academy of Pediatric Allergy and Respiratory Disease have jointly operated the Nation-wide pollen observation network. Currently, fourteen Hirst type traps (Burkard Seven-day recording volumetric spore trap) are operating at twelve cities. Airborne pollen was collected every day from all samplers at all collection sites. Each pollen species was morphologically identified and classified by its size, color, pore shape, and surface pattern. The observed pollen is composed of fifteen tree species including pine, and nine weed species.
Based on the observed data, NIMR has established a system issuing day-to-day warnings of allergenic pollens from trees and weeds and offers the risk index of allergic pollen from a dedicated web page. The pollen risk index has four risk levels as mild, moderate, severe, and dangerous based on the symptom levels of pollen allergy patients. Continuous observation through the pollen monitoring network will support both long-term changes in the allergenic plants and the improvement of the day-to-day pollen forecast.
