Oak stands soils ecologo-geochemical peculiarities and oak (Quercus robur L.) leaves heavy metals accumulation in petrochemical pollution conditions

In the article considers the soils geochemical characteristics in industrial pollution conditions and revealed quantitative data, characterizing the oak leaves heavy metals accumulation degree, what is relevant in connection with the annual oak area reduction and a weakened oak state in intense long-term industrial pollution area (on the example of the Ufa industrial centre).
