Abstract

The present study examined the ability of certain Mediterranean plants to absorb Mn ++ when irrigated with wastewater effluents following treatment, the relative absorption of Fe ++ and Mn ++ , as well as the endurance of such plants to high Mn ++ concentrations in the water used for their irrigation. The experimental plants used in the study were Olea europaea , Nerium oleander and Geranium sp . These plants were irrigated with secondary treatment wastewater effluents, with water commonly used for irrigation in the area, and with water enriched with high concentrations of Mn ++ . The results showed that irrigation of the plants with wastewater treatment effluents resulted in slightly elevated concentrations of Mn ++ and Fe ++ in the leaves, the roots, and in the soil. On the contrary, irrigation with water enriched with high concentrations of Mn ++ (as high as 1000 mg/L) resulted in correspondingly high Mn ++ concentrations in the plants under study. The accumulation of Mn ++ was much higher in the roots than in the leaves of these plants. In the case of Mn ++ enriched water irrigation, the corresponding concentrations of Fe ++ in the roots, in the leaves, and in the soil indicated the existence of strong antagonism between these two elements. All plants exhibited tolerance to high concentrations of Mn ++ .
