“…Based on these values, metals can be (Ouzounidou 1995, Ouzounidou et al 1997) the toxicity of Pb is low in comparison to the toxicity of these both metals (Mohan and Hosetti 1997) and this statement was fully confirmed during our experiments with S. alba seedlings. A good agreement for the Cd inhibitory effect was found for the root elongation of S. alba seedlings as compared with those reported by Ouariti et al (1997) for tomato seedlings. However, the comparison with Ouzounidou's et al (1997) reports for other plants confirmed differences between plant species used.…”

The chronic ecotoxicological effects of Cd, Cu, Pb, Se and Zn were determined within this study. Mustard seedlings (Sinapis alba L.) were used as a model subject for the tests. The phytotoxicity was determined through the root growth inhibition and photosynthetic pigments production (chlorophyll a, b, total carotenoids). The metal accumulation in the roots and cotyledons was also determined using the AAS methods. On the basis of IC 50 values and their 95% confidence intervals (CI) for the root elongation of S. alba seedlings, metals can be arranged in the rank order of inhibition as follows: Cu > Se > Cd > Zn >> Pb. When the photosynthetic pigments production was determined, Se demonstrated the lowest inhibitory effect on all pigment types and Pb did the highest. The accumulated amount of metals from hydroponic solution into the roots and cotyledons decreased in the order Cd > Zn > Se > Pb > Cu.

“…Cadmium has been shown to cause many morphological, physiological, biochemical and structural changes in plants, such 322 as water imbalance, inhibition of seed germination and photosynthesis, reduction of growth, especially of root growth, disturbances in mineral nutrition and sugar metabolism, and therefore strongly influences biomass production (Sanità di Toppi and Gabbrielli, 1999;Moussa, 2004), finally leading to the death of the plant (Kahle, 1993). Cadmium produces alterations in the functionality of membranes by inducing changes in lipid composition (Ouariti et al, 1997), affecting the enzymatic activities associated with membranes, such as that of H + -ATPase (Fodor et al, 1995), and decreasing the photosynthetic rate due to the reduced chlorophyll content and the enzymatic activity involved in CO 2 fixation (Greger and Ögren, 1991). In many plants Cd enhances the level of lipid peroxidation and causes alterations in antioxidant systems (Somashekaraiah et al, 1992).…”

Treatment with CdCl 2 (0, 100, 400 and 1000 µM) resulted in the inhibition of root dry biomass and root elongation and to increased Cd accumulation in the roots. These treatments also decreased the relative water content, chlorophyll content, 14 CO fixation, phosphoenol pyruvate carboxylase and ribulose-1,5-bisphosphate carboxylase activity and abscisic acid (ABA) content, while increasing the malondialdehyde, hydrogen peroxide and free proline contents and causing changes in the chloroplast and root ultrastructure. Pretreatment of seeds with SA (500 µM) for 20 h resulted in the amelioration of these effects.

“…More retardation was observed in root growth than shoot growth in both plants. The reduction in growth is also consequence of zinc interference with nutrient uptake (Chaney, 1983 andKaya et al, 2000), specific enzyme activities (Quariti et al, 1997) and certain essential metabolic events (Tripathy and Mohanthy, 1980; Van Assche and Clijsters, 1990; Alia et al, 1995).…”
