Accumulation of cobalt and nickel in soil, litter, and organs of Scots pine in the conditions of the Yelets industrial center

Information was obtained on the content of cobalt and nickel in soil, litter, and organs of Scots pine in the conditions of the Yelets industrial center. It was found that, under pollution conditions, the content of cobalt and nickel in vegetative organs, soil, litter is higher than the control values. Moreover, their content increases both during the growing season and with an increase in the age of the pine (needles and shoots). There is an uneven accumulation of metal in various organs of Scots pine. A high level of correlation was noted: between the content of cobalt in the soil and needles of the 1st year, shoots of the 1st year - PP No. 1 (r = 0.86; r = 0.78); between the content of cobalt in the soil and bark, litter - PP No. 2 (r = 0.99; r = 0.96); between the nickel content in the soil and needles of the 1st year, needles of the 2nd year, shoots of the 1st year - PP # 1 (r = 0.84; r = 0.78; r = 0.80); between the nickel content in soil and needles of the 1st year, shoots of the 1st year, bark, litter - PP No. 2 (r = 0.92; r = 0.89; r = 0.78; r = 0.87).
