Monitoring of heavy metal residues in cauliflower and their respective health hazards
Abstract
The safety of food plays important role in the growing vicinity of worldwide because it’s direct attitude on human health. Safe food production is vital feature of food safety and quality as well as human. To study the level of heavy metal residues in cauliflower grown in peri-urban area of district Faisalabad and to compare the level of heavy metal residues with their respective maximum residual limits (MRLs). Ten farmers growing cauliflower in the peri-urban environment of district Faisalabad were randomly selected. Cauliflower samples grown in the peri-urban farming systems of district Faisalabad were collected at optimum maturity stage. Thirty samples of each vegetable were procured from the selected farmers. Samples were kept in polyethylene air tight bags then transported to the laboratory of National Institute of Food Science and Technology, University of Agriculture, Faisalabad for immediate processing. The heavy metals were determined by Atomic Absorption Spectrophotometer. The results pertaining heavy metals residues in different cauliflower samples collected from District Faisalabad showed variable results. The heavy metal residues varied as nickel 0.013 to 0.523 mg kg-1, lead 0.012 to 1.442 mg kg-1, zinc 0.236 to 1.734 mg kg-1, copper 0.121 to 0.548 mg kg-1, arsenic 0.016 to 0.79 mg kg-1and mercury 0.003 to 0.043 mg kg-1. The cauliflower samples are contaminated with number of heavy metals because it is grown with sewerage water that should not disposed after suitable treatment and wastewater is the single largest contributor of heavy metals accumulation in cauliflower.
