Vegetable gardens in cities provide communities with fresh vegetables but also may contribute towards public exposure to metals present in soil from historical pollution. Contamination of some Melbourne garden soils with Pb (range 12.9-773 mg kg-1 in soil) was found with some soils exceeding the Australian human health screening criteria for residential land use of 300 mg kg-1. Cadmium concentrations (0.12-1.04 mg kg-1) were above the ambient background soil concentrations of <1 mg kg-1. Nickel concentrations (7.6-40.5 mg kg-1) and Cr (11.6-49.4 mg kg-1) were within the range of expected ambient background concentrations. Distance from the nearest arterial road, house age and the likely use ..
