For the first time a study of heavy metals in the pollen Pinus sylvestris L. atomic absorption method. Identified anomalies and identify fertility and viability of pollen grains of Pinus sylvestris L., depending on the growing area by conventional cytological techniques using acetocarmine, Lugol’s solution, and nutrient agar medium based on germination of pollen grains. Pollen fertility declines in the contaminated area. Percentage and range of abnormalities increases in adverse environmental conditions. The correlation between the appearance of some of the anomalies of pollen grains and the concentration of heavy metals in the pollen. Reduced viability and increases the number of pollen grains affected by fungal mycelium in the impact zone.
