“…Soil contamination of Cd is due to both natural and anthropogenic sources such as the non-ferrous metal industry, mining, use and disposal of batteries, metal contaminated wastes and sludge disposal and the application of pesticides and phosphate fertilizers (Chatterjee and Chatterjee 2000;Wong et al 2002). Several studies carried out with different plant species have revealed that Cd is strong phytotoxic and causes growth inhibition and even plant death, although the mechanisms involved in its toxicity are still not completely well understood (Lagriffoul et al 1998;Sandalio et al 2001;Parveen 2004;Vassilev et al 2004). The beneficial effect of Cd at lower doses in different crop plants has been reported by various researchers (Aery and Rana 2003;Khan et al 2008).…”

A pot experiment was conducted to investigate the effects of cadmium and zinc interactions on the accumulation and tissue distribution of cadmium and zinc in tomato (Lycopersicon esculentum Mill.). The results obtained in this study reveal that treatment of soil with Cd, Zn, or Cd-Zn did not improve plant growth as compared to control. The levels of concentrations of Cd and Zn in leaves, shoots and roots were determined. The highest concentration of Cd was 135.0 mg kg 71 d.w. in the leaves, 57.0 mg kg 71 d.w. in the shoots, and 210.0 mg kg 71 d.w. in the roots; Zn concentration ranged from 186.0-776.0 mg kg 71 d.w. in leaves, 126.7-700.0 mg kg 71 d.w. in shoots, and 320.0-2015.0 mg kg 71 d.w. in roots of tomato plant. Significant inhibitory effects of Zn on Cd accumulation in all organs of tomato plant occurred only at toxic levels (100 and 1000 mg kg 71 soil), but the reduction in Cd concentration did not improve shoot and root biomass suggesting that Zn concentration became the dominant factor affecting plant growth. An examination of Cd-Zn interactions and their transfer to soil-plant system indicate their synergistic effect. Increasing Cd and Zn concentrations in soil result in an increase in the accumulation of Cd or Zn in the plant tissues.

“…The presence of excessive amounts of Cd in soil causes reduction in plant growth, disturbances in mineral nutrition and may reduce biomass (Sandalio et al 2001;Jiang et al 2004;Parveen 2004;Dong et al 2005). Pyrometalurgic smelting of Zn, Pb and Cu ores is the main source of Cd contamination (Purves 1985).…”

A study was carried out on the influence of increasing levels of single and multiple soil contamination with Cd, Pb and Zn (5, 15, 25 or 50 mg Cd kg 71 soil; 125, 250, 500 or 1000 mg Pb and Zn kg 71 soil) on growth, chlorophyll and Cd content of tomato plants. At a level of Cd 5 Pb 125 Zn 125 , Pb 2þ and Zn 2þ have a protective effect and decrease the phytotoxic effect of Cd 2þ on tomato plant. At higher levels, growth parameters (shoot weight, root weight and chlorophyll content) are reduced parallel to the enhancement of Cd concentration. At a level of Cd 15 Pb 250 Zn 250 , Pb 2þ and Zn 2þ alleviate the unfavorable effects in triple combinations. Above the level Cd 15 Pb 250 Zn 250 , Pb 2þ and Zn 2þ interact antagonistically with Cd 2þ . The reduction of tissue Cd content is not always accompanied by an alleviating effect of Cd phytotoxicity. The Cd-Zn combination decreases the tissue Cd content more effectively than Cd-Pb, but its phytotoxic effect is more pronounced. The Cd toxicity depends more on free Cd ions than on total tissue Cd content. The translocation of Cd from root to leaves is higher compared to its accumulation from root to shoot.
