“…The results here indicated that N. officinale could tolerate Cr up to a concentration of 20 mM. Earlier workers who studied Cr bioaccumulation stated that aquatic plants could develop strategies to defend themselves against this potential stress (Sinha et al, 2005;Vajpayee et al, 2000). Observations from the present study support these earlier reports.…”

The aim of this study is to determine the effects of Cd, Co and Cr on the growth of watercress (Nasturtium officinale) and to determine the bioaccumulation properties of these heavy metals by the plant. N. officinale individuals were exposed to different concentrations of Cd, Co and Cr for 72 h. Relative growth rates (RGR) and bioconcentration factor (BCF) ratios were calculated for each metal concentration. RGR values of plants exposed to Co slightly increased in lower concentrations, but then decreased again. In contrast, RGR values of plants exposed to Cd and Cr decreased linearly. Significant positive relationships were observed among the concentrations of Cd, Co and Cr in N. officinale and in the culture solution. BCF ratios were highest for plants exposed to Co, and lowest for plants exposed to Cr. The most efficient uptake of Cd, Co and Cr occurred at the external solution concentrations at 0.5, 0.5 and 10 mM, respectively.

“…Contrary to our results, Razinger et al (2007) and Razinger et al (2008) found that Cu elicits a stronger oxidative stress as compared to Cd and is therefore more toxic to the test plants. In accordance with our observations, similar results were obtained after Cu treatment in Ceratophyllum demersum L. (Devi and Prasad, 1998;Mishra et al, 2006) and Pistia stratiotes (Sinha et al, 2003).…”

Aquatic plants have been identified as potentially useful for accumulating and bioconcentrating heavy metals. This study was developed to test the hypothesis that nutrient enrichment enhances the metal tolerance of floating macrophytes. Relative growth rates (RGR), photosynthetic pigments (chlorophyll a, b and carotenoid), malondialdehyde (MDA) content, and electrical conductivity (EC) were measured in Lemna gibba exposed to different cadmium and copper concentrations in laboratory conditions. Relative growth rates were negatively correlated with metal exposure, but nutrient addition suppressed this effect. Photosynthetic pigment levels were negatively correlated with metal exposures, and nutrient addition attenuated chlorophyll decrease in response to metal exposures. MDA content and EC also showed sharp increases at higher concentrations, indicating oxidative stress. This study indicates that nutrient enrichment increases the tolerance of Lemna gibba to metals, and that Lemna gibba is a suitable candidate for the phytoremediation of low-level copper and cadmium pollution.

“…McGrath (1987) reported that Zn, Ni and Cd were the most bioavailable metals, whereas Pb and Cr were scarcely available, after estimating the metal uptake of plants grown on sludge-treated plots. Sinha et al (2005) reported that most of the Cr in Pistia stratiotes was found in the roots, which is probably due to binding of metals to the ligands and thus reducing its mobility from roots to aerial parts. The same authors reported that this behaviour is a strategy of the plants to limit metal translocation to the aerial parts.…”

The proposal to use sewage sludge (SS) on agricultural fields as a sustainable way to dispose of the waste is based on its high organic and nutrients content. However, the presence of heavy metals (HMs) in sludge can contaminate crops and accumulate in the food chain. The aim of this study was to assess changes in soil fertility, biochemical responses of tomato (Solanum lycopersicum L. cv. Rio Grande) seedlings and the availability of HMs with increased rate application of SS (0, 2.5, 5 and 7.5%). Leaf chlorophyll content, nutritional status, proline, membrane peroxidation, stomatal conductance and HM accumulation were investigated. Results showed that the soil pH decreased, whereas soil salinity, organic carbon, total N, available P and exchangeable Na, Ca, K and HM content increased significantly with increasing application rates of SS. Among the three HMs (Zn, Cu and Cr), Zn had the highest capacity for transferring from soil into plants. Low metal translocation was observed from roots to leaves. The 7.5% SS dose decreased biomass production and caused a decline in chlorophyll content and stomatal conductance. However, lipid peroxidation and proline contents increased. Therefore, the use of 2.5 and 5% doses of sewage sludge in agriculture would be an efficient and costeffective method to restore the fertility of soil and an environment-friendly solution for disposal problems.Additional key words: sewage sludge amendment; soil fertility; biochemical responses; Solanum lycopersicum.
