Abstract:
The importance of food safety is a major area of interest worldwide as contaminants particularly heavy metals are destroying its quality. The objective of the present study is to determine the total intake of heavy metals concentration including lead(Pb), cadmium(Cd), copper(Cu), and chromium(Cr) in 28 samples that were collected from different stores in Manawan and Ravi Road, Lahore, Pakistan. The samples were dried, digested, and then analyzed by AAS. The highest mean concentrations of heavy metals in liquid foods were in the order Pb (0.0094 to 0.04 ) mg/kg >Cr (0.257 to 0.842) mg/kg> Cu (0.21 to 1.756) mg/kg> Cd 0. 001 mg/kg which were all below the detection limit (BDL) except Pb while for semi-solid or solid food, the order of concentrations was Pb (0.26) mg/kg>Cu (0.73 to 21.02) mg/kg> Cr (0.05 to 1.71) mg/kg> Cu (0.11 to 8) mg/kg which were all below the detection limit. The results obtained were compared with permissible limits set by Pak NSDWQ, USEPA, and WHO/ FAO. The estimated daily intake (EDI) of Pb, Cd, Cr, and Cu lies in the range of 45 to 670 µg/person, 14.5 to 70 µg/person, 1.12 to 3.44 mg/person, and 13.5-60 mg/person. The noncarcinogenic risk was evaluated from the values of the target hazard quotient (THQ) which is < 1 for individual metals and the hazard index (HI) for multiple combined heavy metals >1 indicating that the consumption of these food items together can pose health risks. It was concluded that the people residing in the study area are at potential health risks and food authorities should keep a check on the contamination of food.
