At the same time, the content of the studied vitamins in wild black currant berries from the Vilyuy group of districts was less: vitamin E – 68.53–76.46 mg/kg; C – 839.03–953.50 mg/100g; B1 – 2.43–2.63 mg/kg; B2 – 12.76–14.08 mg/kg; B6 – 16.73–18.68 mg/kg. Studies on the content of heavy metals in the soil and berries in the Central and Vilyuy zones of Yakutia. Proved that the amount of heavy metals contained in the soil, and their removal by black currant berries is different. There is no cadmium or mercury in wild currant berries.
