Abstract
Bioindication is a convenient tool for assessing the environmental situation and the level of pollution of natural and man-made landscapes. One of the most important indicator is the fluctuating asymmetry of plant organs, less common – organs of animals and humans. In 2019, we studied the fluctuating asymmetry of Pinus sylvestris L. located in the industrial zone (Yanino-1), as well as in city parks of St. Petersburg (Alexandrino, Sergievka) and Moscow (Sokolniki). The dependence of the fluctuation asymmetry on the sample size is studied, the volumes of samples are substantiated, an algorithm for processing experimental data is proposed, which allows increasing the accuracy of experiments, avoids false positive or false
