Paper Title:
Determination of Heavy Metal Elements in Farm Products Taros and Agricultural Soil by Inductively Coupled Plasma-Optical Emission Spectrometry and Assessment
  Abstract

This study was designed to determine the heavy metal concentrations in soils and food crops and estimate the potential health risks of metals to polluted food crops and soil, so agricultural soil for the cultivation and taro were main objects of study, taro were taken in the HNO3-H2O2 wet digestion, while soil were taken to HCl-HNO3-HF-HClO4 wet digestion by (ICP-OES),then coments and analysis on the samples were carried out by comparing with their limits of relative state standards. The analytical results indicate that for all of the analyzed elements the relative standard deviations (RSD) are 0.9-4.9% and the recoveries of most elements are in the range of 96.84-104.96%. Zn, As, Cd and other contents in soil samples were detectable beyond their limits of state standards, while heavy metals contents in the investigated samples were found at different polluted levels. Cd, Cr, As, Zn, Cu in taros also exceeded the national standard. It was found that there are enrichment of heavy metals in taro. It is concluded that the present techniques are suitable for the routine determination of heavy metals concentration in the food crops-soil systems.
