HUMAN HEALTH RISK EVALUATION OF SELECTED METALS IN VEGETABLES IRRIGATED WITH FRESH WATER
Faria Nisar
Abstract
The aim of this study was to find the accumulation of metals such as zinc (Zn), manganese (Mn), chromium (Cr), iron (Fe), copper (Cu), calcium (Ca), plumbus (Pb), natrium (Na), potassium (K), magnesium (Mg) and calcium (Ca) in selected vegetables; Brassica oleracea capitata (Cabbage), Raphanus sativus (Radish) and Brassica rapa (Turnip), and their soil samples. The plant material and soil samples were collected and analysed from selected areas (Bandala, Serla and Makhal) of District Bhimber, AJK. The Atomic Absorption Spectrophotometer (AAS) was used to evaluate metals in the selected vegetables and soil samples. The analysed results indicated that there was no substantial change (p>0.05) among the metals evaluated in the vegetables. The accumulation factor of vegetables did not demonstrate the biomagnification of examined metals except Na, Mg, Ca and Pb. The high HRI value of Pb (4.92) warns about the serious threat to the vegetable consumers in the studied area.
