摘要: ABSTRACTThis study reports the determination of trace essential (Co, Cr, Cu, Se, and Zn) toxic (Al, As, Cd, Hg, Pb) elements in greenhouse tomatoes, peppers, cucumbers from supermarkets Seoul, Busan, Gangneung, Daegu, Daejeon, Gwangju, South Korea using inductively coupled plasma mass spectrometry, optical emission spectroscopy, direct mercury analysis. The methods were validated by linearity, limits detection quantification, precision, accuracy, recovery measurements that provided satisfactory results all cases. Among elements, Zn was found to have highest concentrations (0.84–2.5 mg/kg) followed Cu (0.21–0.62 mg/kg) Cr (0.01–0.06 mg/kg). mean (mg/kg) order Al > Pb > As > Cd > Hg for tomatoes Al > Pb > Cd > As > Hg peppers; below permissible set World Health Organization human consumption. estimated dietary...
