Status and Trend of the Main Allergenic Pollen Grains and Alternaria Spores in the City of Rome (2003–2019)

Today a large part of the European population is exposed to levels air pollution exceeding standards recommended by World Health Organization. Moreover, and seasonal emission allergenic pollen are progressively affecting human health can cause severe allergic reactions, particularly when combines with allergen peaks. Unlike atmospheric pollutants anthropogenic origin, sources have pulsating trend that leads high values in flowering period close to, or equal zero rest year. This aspect makes essential definition data coverage for main taxa. For quality assessment detailed classification criteria monitoring stations defined international standards, not same from Standards Sampling analysis airborne grains fungal spores. paper describes status concentration trends Alternaria spore measured Rome 2003 2019 Aerobiological Monitoring Center Tor Vergata (Rome) calculated Seasonal Kendall test open-source OpenAir R package.
