INVESTIGATION OF THE ELEMENTAL COMPOSITION OF THE PLANT PRUNUS CERASUS L. BY ICP-MS.

Abstract

The elemental composition of cherry leaves, fruits, stems and seeds was studied by inductively coupled plasma mass spectrometry. In the studied plant samples, the amount of 43 macro- and microelements was determined. Elements were determined in the amount of 24908.25 mg/l in leaves, 18145.57 mg/l in stems, 16277.86 mg/l in stones and 13365.99 mg/l in fruits. Leaves, seeds and fruits of cherries contain the highest amount of calcium, and stems - potassium. The total amount of macronutrients decreases in the following order: in leaves 23125.221 mg/l, in stems 17192.303 mg/l, in seeds 15037.554 mg/l, in fruits 12810.727 mg/l. The amount of macronutrients in the seeds was 92.84%, in the fruits 94.75%, in the leaves 92.38% and in the stems 95.84%. Among the trace elements, such elements as Fe, Si, Al, Sr, Mn, B, Ti, Zn and Cu have a greater number. The amount of iron in the studied samples was much higher and ranged from 347.638 mg/l to 1018.509 mg/l. Among the toxic elements, Pb, Hg, Cd and As were identified, among which lead has a relatively high concentration. The amount of lead in leaves and stones is higher than in stems and fruits.
