This study involves identifying the levels of some essential and heavy elements (i.e., sodium (Na), potassium (K), magnesium (Mg), phosphorus (P), calcium (Ca), chromium (Cr), manganese (Mn), iron (Fe), cobalt (Co), nickel (Ni), copper (Cu), zinc (Zn), arsenic (As), cadmium (Cd), and lead (Pb)) in red onion (Allium cepa L.) bulbs and leaves, white radish (Rphanus sativus L.) roots and leaves, and cucumber (Cucumis melo var.) fruit cultivated in three distinct villages (Haran Dian, Althaalab, and Abrlasloom) in Delta Tuban (Lahij Governorate/ Yemen). The collected samples had been wet digested using aqua regia. Then, metal concentrations were measured using inductively coupled plasma-optical emission spectrometry (ICP-OES). All samples showed high concentrations of essential elements. On the other hand, heavy metals (Mn, Fe, and Cu) exceeded the limit allowed by FAO/WHO while Zn was under allowed limits. Moreover, Cr, Co, Ni, As, Cd, and Pb revealed a varied range of concentration levels in the targeted samples.

Keywords : Essential Elements, Heavy Elements, Vegetables of Lahij, Concentration Determination.
