Summary
Significantly higher contents of boron, molybdenum and zinc were observed in cabbages in urban than in rural areas. The levels of extractable boron, copper, lead, nickel and zinc were markedly enhanced in the urban soils but there was no corresponding enhancement of the levels of copper, lead and nickel in the cabbages.
