Trace metals in vegetables and fruits cultivated around the surroundings of Tummalapalle uranium mining site Andhra Pradesh India

摘要

Vegetables (Tomato – Solanum lycopersicum, green chilli – Capsicum annum and bitter gourd – Momordica charantia) and fruits (Banana – Musa acuminata colla, papaya – Carica papaya and mosambi – Citrus limetta) from the cultivated areas around the Tummalapalle uranium mining site were analyzed for trace metals (Al, Cr, Mn, Fe, Ni, Cu, Zn, Pb, Be, V, Co, Cd and U) using inductively coupled plasma-mass spectrometer (ICP-MS). As per the estimated data, the concentrations of trace metals in vegetables and fruits are found in the range of 47.5–7.8 mg/kg for Al, 9.7–1.0 mg/kg for Cr, 3.8–1.0 mg/kg for Mn, 75.5–13.9 mg/kg for Fe, 1.4–0.2 mg/kg for Ni, 2.3–0.8 mg/kg for Cu, 9.2–3.1 mg/kg for Zn, 0.2–1.4 mg/kg for Pb, 19.2–1.9 μg/kg for Be, 96.1–15.8 μg/kg for V, 48.2–12.9 μg/kg for Co, 46.5–2.3 μg/kg for Cd and 16.4–2.7 μg/kg for U. The trace metals observed are compared to the literature reported values. Trace elemental data were subjected to statistical analysis to examine the interrelationship between the investigated trace elements and possible source identification of the trace metal contamination in vegetable and fruits. Daily intake of trace metals through ingestion of vegetables and fruits are also calculated.
