Abstract
Mineral and heavy metal contents of ground tumbleweed seed, date seed powder and Arabic coffee kernels and their hot coffees were determined by inductively coupled plasma atomic emission spectrometry (ICP-AES). Calcium, K, Mn and Na contents of ground coffee samples ranged from 1200.38 to 6752.66 mg/Kg; 17841.6 to 83649.88 mg/Kg; 6158.43 to 2120.29 mg/Kg; 232.74 to 553.64 mg/Kg, respectively. Iron contents of ground coffees vary from 2.83 to 109.03 mg/Kg while Fe content of hot coffees varied from 15.31 to 616.60 mg/Kg. Cadmium, Mn, Mo, Pb and Zn contents of hot coffee drinks were found at the high levels. Important differences were generally detected among mineral contents of ground seeds and hot coffee drinks.
