Summary. Allergic diseases of airways, caused by Betula pollen, represent a considerable clinical problem in up to 10-20 % of the population in Northern and Central Europe. The analysis of specific IgE antibody by RIDA Screen Allergy-test, conducted by the Department of Allergy, Institute of Occupational Health, WHO Collaborating Center, Skopje, in patients with indication of allergy problem, shows that Betula pollen is the most significant allergen (19%) compared to other tree pollens in R. Macedonia. To prevent the appearance of the symptoms, physicians need precise and early information on the pollination data of the major allergenic species. The aim of this study was to determine characteristics and occurrence of Betula pollen in Skopje atmosphere, based on a 3-year observation (2003–2005), and to compare pollen season start dates calculated by different methods. Pollen samples were collected using the Hirst volumetric method with a 7-day LANZONI VPPS 2000 sampler. Two–hour counts were used to establish diurnal periodicity with one transverse traverse of the slide being counted every two hours, and the appropriate factor applied. Three methods (Sum 75, 30 and 1 pg/m3) were used for determination of the start dates of the Betula pollen season and the results were compared. The total annual pollen sum increased during the observed period. In 2003, 2004 and 2005, the highest daily pollen concentrations were 97, 460 and 131 pg/m3, respectively. The earliest Betula pollen season starts were calculated by the 1 pg/m3 method.

POLEN BREZE (BETULA SP.) U ATMOSFERI SKOPJA
Kratak sadržaj: Alergijske bolesti disajnih puteva uzrokovani polenom breze predstavljaju značajan klinički problem obuhvatajući 10-20% populacije Severne i Centralne Evrope. Rezultati Centra za alergiju Instituta za medicinu rada, SZO Kolaborativnog centra u Skopju u odredjivanju specifičnog IgE metodom RIDA Allergy Screen ukazuju da je oko 19% osoba sa respiratornim alergijskim manifestacijama senzibilisano na polen breze. Precizne i blagovremene informacije o periodu polinacije najvažnijih alergogenih biljaka neophodne su za prevenciju simptoma. Cilj ovog rada je odredjivanje početka i drugih karakteristika sezone polena breze u atmosferi Skopja u periodu 2003-2005 primenom različitih metoda. Skupljanje polenskih primeraka izvedeno je volumetrijskim metodom, a korišćen je LANZONI VPSS 2000 sempler. Dnevni periodicitet bio je odredjen rezultatima dvočasovnih merenja i korigovan odgovarajućim faktorom korekcije. Tri metoda (Sum 75, 30 i 1 pg/m3) su primenjena za odredjivanje početka polenske sezone sa komparacijom dobijenih rezultata. Naši rezultati ukazuju na povećanje ukupne godišnje polenske sume u ispitivanom periodu. Najveće dnevne polenske koncentracije u 2003, 2004 i 2005 bile su 97, 460 i 131 pg/m3. Najraniji početak polenske sezone bio je odredjen metodom 1 pg/m3.
