Peanut (Arachis hypogaea L.), which is one of the most important members of the legumes family, contains appreciable amounts of high-quality dietary oil and vegetable protein. It can be added to many foods to enhance their levels of high-quality protein in diets lacking in nutrition. In this study, 18 essential elements (V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Se, Mo, Mg, P, S, K, Ca, Cl, Br and I) and 4 non-essential potentially toxic elements (Cd, Sn, Hg, and Pb) in 42 peanut samples from Mediterranean region of Turkey were analysed by using an energy-dispersive X-ray fluorescence spectrometer. The most abundant essential elements of K, P, S, Ca, Mg and Cl were determined with average concentrations of 13437, 5058, 3451, 1786, 1759 and 209 mg kg−1, respectively. The daily intake of potentially toxic elements for an adult person due to the consumption of peanuts was estimated based on the measured concentrations of the potentially toxic elements (V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Sn, Cd, Pb, and Hg). The results revealed that peanut samples contain health-enhancing nutritional elements and consumption of peanut samples as food does not pose any health risk for toxic metals.

Groundnut (Arachis hypogaea L.) is one of the most important of all legumes and contains appreciable amounts of dietary oil and protein. Groundnut is added to many foods to enhance their levels of high-quality protein in diets lacking in nutrition. In this study, 51 groundnut samples were collected from the Mediterranean region of Turkey and analysed for naturally occurring radioactive isotopes of radium (226Ra), thorium (232Th) and potassium (40K). The activity concentrations of 226Ra, 232Th and 40K in groundnut samples varied from 2.9 ± 0.8 to 7.6 ± 1.0 Bq kg-1 (dw), with an average of 5.4 Bq kg-1 (dw); 4.4 ± 0.9 to 10.7 ± 1.2 Bq kg-1 (dw), with an average of 6.9 Bq kg-1 (dw) and 246.3 ± 18.2 to 541.8 ± 40.1 Bq kg-1 (dw), with an average of 427.1 Bq kg-1 (dw), respectively. The annual effective radiation dose was estimated to assess the health hazards caused by the ingestion of groundnut samples based on the measured activity concentrations of the radionuclides contained in them. The annual effective radiation dose varied from 6.5 to 10.1 μSv y-1, with an average of 8.3 ± 0.1 μSv y-1. The results revealed that consumption of Turkish groundnuts does not pose any radiological health hazards.
