Influence of Transpiration on Cadmium (Cd) and Lead (Pb) Uptake by Cabbage, Carrots and Lettuce from Irrigation Water in Ghana

Ebenezer Mensah, Samuel Nii Odai, Emmanuel Ofori and Nicholas Kyei-Baffour

Abstract:
A study was conducted on Cd and Pb concentrations effects on transpiration rates of cabbage, lettuce and carrots. The vegetables were established on experimental plots and irrigated with irrigation water of 0.05 and 0.1 mg L-1 of Cd and 30 and 50 mg L-1 of Pb, all values above the permissible FAO/WHO standards for crop irrigation. The field experiment was carried out on a sandy soil. Cadmium concentration of 0.05 mg L-1 of irrigation water reduced transpiration rates of cabbage and lettuce by 55.9 and 10.7%, respectively but increased for carrots by 268%, compared to the control (0 mg L-1 concentration of irrigation water). At Cd irrigation water concentration of 0.1 mg L-1 the transpiration rates of cabbage and lettuce reduced by 60.97 and 16.56%, respectively whilst that of carrots increased by 186.9%. For Pb treated irrigation water, the transpiration rates of 30 mg L-1 of Pb concentration in the irrigation water reduced by 56.6, 11.1 and 35.9% for cabbage, lettuce and carrots, respectively. At 50 mg L-1 Pb concentration in the irrigation water, the transpiration rates of cabbage, lettuce and carrots reduced by 72.9, 41.7 and 24.5%, respectively, compared to the control (0 mg L-1 concentration of irrigation water) samples.
