POTENTIAL TOXIC METAL ACCUMULATION IN GRAINS OF WHEAT VARIETY (GALAXY-2013) IRRIGATED WITH SUGAR INDUSTRY WASTEWATER: HEALTH RISK TO THE PUBLIC

Abstract
This study was carried out to investigate the potential toxic metals accumulation in wheat variety (Galaxy-2013) under different treatments of industrial wastewater irrigation. Atomic absorption spectrophotometer (AA-6300 Shimadzu Japan) was used to assess the concentration of the potential toxic metals, iron (Fe), copper (Cu), chromium (Cr), and cadmium (Cd). An atomic absorption spectrophotometer equipped with a graphite furnace and D2 corrector (Perkin–Elmer Model 503) was used to determine cobalt (Co) contents. Accumulation values of potential toxic metals in the present study were higher than these maximum limits in vegetables except for Cd. Also, health risk index for Cd was observed above the permissible limits. Pearson’s correlation coefficient identified the association between the potential toxic metals content in soil and as well as in plant. The study consequences determined that Cd was significantly positively correlated while Cr, Cu, and Fe showed positive and non–significant correlation. Health risk index for Cd was determined as higher than 1 and so, the consumption of wheat is not free of risk due to high level of Cd.
