A Comparison of The Levels of Heavy Metals in Cabbages Irrigated With Reservoir and Tap Water

A studywas carried out in Malawi to determinethe levels of heavy metals in cabbages grown in gardens irrigated with reservoir and tap water. The concentrations of cadmium, lead and chromium were determined in the leaf and in the corresponding soils in order to assess whether the amounts in the soils reflected the accumulation of heavy metals in plants. The results showed that the levels of the heavy metals in both the cabbages and soils irrigated with reservoir water were generally low. The concentration of cadmium in reservoir water irrigated cabbages was significantly higher (p
