| description | Introduction: Consumption of green leafy vegetables containing heavy metals especially grown in previously anthropogenic polluted areas such as landfill and mining areas is identified as one of the routes for these contaminants to be accumulated in human body which resulting to various health effects such as dysfunction of renal system, destruction of liver and anaemia. Objective: This study is done to determine the concentration of heavy metals (Cu, Pb, Cd, Mn, Ni, Zn, Fe) in the selected vegetables and with the associated soils. Methodology: Thirty samples for each types of vegetables (spinach and mustard green) and their corresponding soils were taken at the Upol's agricultural field to be digested at the laboratory by using acid digestion before being analysed with Atomic Absorption Spectrophotometer (AAS). Results: From the findings obtained, the concentration of heavy metals Pb (0.46 mg/kg), Cd (1.0 mg/kg), Ni (5.18 mg/kg) and Zn (107.7 mg/kg) in spinach while the level of Pb (0.31 mg/kg), Cd (0.62 mg/kg) and Ni (4.34 mg/kg) in mustard green were exceeded the allowable maximum levels of heavy metals recommended by World Health Organization (WHO). However, the concentration of heavy metals in the soils were below permissible limits recommended by WHO. The concentration of these heavy metals in vegetables then were used to evaluate the potential health risk based on the hazard quotient (HQ) among the consumer at Bestari Jaya, Selangor. The value of HQ for Cd, Zn and Mn were more than 1 indicated the consumption of these types of vegetables tend to pose a health risk among the consumer. Conclusion: It is compulsory to monitor and assess the concentration of heavy metals in plant tissues at every agricultural field to avoid the accumulation of these contaminants in human food chain and to enhance the quality of life among vegetables consumers at Bestari Jaya specifically. |
