The Uptake of Heavy Metals by Fruit Type Vegetables Grown in Selected Agricultural Areas

J. Khairiah, M.K. Zalifah, Y.H. Yin and A. Aminah

A study on the uptake of heavy metals by fruit vegetables from agricultural areas was conducted at Agrotek, Sepang and Bangi, Selangor. The objective of the study was to determine the uptake of heavy metals by chilies (Capsicum annum) and long beans (Vigna sinensis) from the soil. Heavy metals studied were Pb, Cd and Zn. Wet digestion method was used for heavy metals analysis in the vegetables. Heavy metals from soil samples were extracted by sequential extraction method, which extract heavy metals from easily and freely leachable fraction (EFLE), acid reduction (AR), organic oxidation (OO) and resistant fraction (RR). The results of the study showed that the level of Zn content in long beans (Vigna sinensis) was higher than in chilies (Capsicum annum). However the concentrations of heavy metals studied in these vegetables were still below the maximum level allowed by the Malaysian Food Act (1983) and Food Regulations (1985) for Pb (2.00 mg kg^-1), Cd (1.00 mg kg^-1) and Zn (30.00 mg kg^-1).
