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