“…Our finding is in agreement with other observations reported in other plants growing on metal-polluted soils (Ali et al 2011;Lu et al 2011;Liu et al 2012). The decrease in F v /F m may be a result of an increase in protective non-radiative energy dissipation (non-photochemical quenching) associated with a regulated decrease in photochemistry and photosynthetic rate, photo-damage of PSII centers or both (Mechri et al 2011). However, compared to the control condition, the chlorophyll content and F v /F m value reductions detected in exposed A. elatius were more pronounced than that in exposed S. transcaspicus, which indicated that A. elatius might be more affected by metal-induced oxidative stress.…”

The application of vegetation cover for the phytomanagement of heavy metal-polluted soils needs prior investigation on the suitability of plant species. In this study, behaviors of Arrhenatherum elatius and Sonchus transcaspicus, two native perennial grasses that currently grow in a mine tailing, were investigated through plant metal concentration, phytotoxicity and their detoxification responses. Both of the species accumulated Ni, Cu, Cd, Co, Mn, Pb, Cr, and Zn in shoots far below criterion concentration as a hyperaccumulators; thus, neither of them were found to be hyperaccumulators. A. elatius accumulated metals in roots and then in shoots, on the contrary, in S. transcaspicus metals were preferentially accumulated in shoots. Plants exposure to such metals resulted in oxidative stress in the considered organs as indicated by the changes in chlorophyll fluorescence, chlorophyll contents, malondialdehyde (MDA) levels and antioxidative enzyme activities. A. elatius seemed to be more affected by metal-induced oxidative stress than S. transcaspicus. Correspondingly, S. transcaspicus showed a greater capacity to adapt to metal-induced oxidative stress, depending on more effective antioxidative defense mechanisms to protect itself from oxidative damage. These findings allowed us to conclude that both of these plant species could be suitable for the phytostabilization of metal-polluted soils.

“…Several studies have focused on the effects of irrigation with treated wastewater and the application of olive mill wastewater and moderate saline water on soil chemical properties (Al-Absi et al, 2009;Mechri et al, 2011;Bedbabis et al, 2010aBedbabis et al, , 2014 and little information is known about the effects of TWW on chemical properties of a cultivated sandy-silty soil. Studies on the effect of TWW on olive's growth, productivity and oil quality in Tunisia are scarce (Bedbabis et al, 2009(Bedbabis et al, , 2010aBen Rouina et al, 2011).…”

“…Soil water repellency could lead to non-equilibrium water flow and solute transport in soils (Jarvis et al 2008). Negative effects of OMW on soil properties have also been recorded, including the immobilization of available N (Mechria et al 2011) and either decreases or increases of available elements and salts (López et al 1996). In many studies, various effects of wastes applied to soil were recorded, but mainly occurred shortly after amendment (Albich et al 2000;Martens et al 1992).…”

To evaluate the effect of olive mill wastewater (OMW) application on soil hydraulic and transport properties, two treatment sites, which had been irrigated with OMW for 5 and 15 years, and one control site being irrigated with freshwater were compared. The transport and leaching experiment results showed that a portion of the total soil water was available for transport processes while the remaining of the soil water was considered immobile and not readily accessible for solutes. The separation in water fractions of different mobilities was surprisingly consistent among OMW treatments. The bromide recovery rate decreased with the application of OMW showing that tracer molecules became trapped within immobile water phases. The application of OMW increased significantly the soil water-holding capacity, whereas the soil hydraulic conductivity in the near saturation range decreased significantly with long-term OMW application. The soil irrigated with OMW had significantly higher organic matter content, lower bulk density and relatively higher total porosity, but lower macroporosity than that of control sites. We concluded that the soil was increasingly coated with complex organic molecules originating from OMW, as a result, solute exchange between inter-and intrasoil aggregate water was hindered. Although OMW could cause soil and water pollution, its use in agriculture is promoted because of high nutrients and organic matter contents.
