peanut, heavy metals, toxicity, maximum permissible concentration


Background. Some metals are necessary for normal physiological processes in a human body. But if their concentration is too high they are toxic for the organism. The level of their concentration in the organism is determined by their content in the environment. Toxic substances enter into food from the environment in the result of damaged process of growth, production or storage of products. Most dangerous toxicants are the salts of heavy metals. Based on literature data on accumulation of heavy metals by plant tissues, metabolism and their toxicity to humans were considered.
Material and methods. 19 sorts of peanuts were the object of the research.: Krasnodarets 13, Krasnodarets 14, Krasnodarskiy 14, Krasnodarskiy 15, AR 1, AR 2, AR 3, AR 4, AR 5, AR 6, VNDIOK 14, VNDIOK 15, Pink large, Pale-pink 1, Pale-pink 2, Pale-pink 3, Dark-red, Malynovyi, Klinskyi. Weight fraction of toxic elements is determined by atomic adsorption method.
Results. The content of heavy metals in different varieties of peanuts spread in Ukraine has been experimentally studied. It is determined that the amount of lead salts in all sorts of peanut is much smaller comparing to the admissible concentration and fluctuates 0.1–0.15 mg/kg. Cadmium salts are also contained in small amounts (0.01–0.03 mg/kg). Such sorts of peanut as Rose-pink 2, AR 2 and AR 4 contain most of the salts of copper. The sorts AR 6, Pink large, Krasnodarskiy 14 and Crimson contain most of zinc.
Conclusion. All sorts of studied peanut do not exceed admissible limit concentrations. Varieties of peanuts that have the ability to accumulate in the slightest heavy metals have been identified: Krasnodarets 14, Krasnodarskiy 15, AR 1, AR 3, AR 4, AR 5, Pale-pink 2, Pale-pink 3, Dark-red.
