Fluctuating asymmetry of birch (Вetula pendula and В. pubescens) leaves has been studied at four sites in the Republic of Karelia: near (2 km away from) pollution sources (Segezha pulp-and-paper mill and Kostomuksha ore mining and processing enterprise), inside green zone of large town (Petrozavodsk) and on the relatively pure (control) territory (Zaonezje, v. Sennaja Guba). No significant trends of change for two asymmetry indexes (traditional and normalized) connected with latitude peculiarities of the environment and anthropogenic load have been revealed.
