In this work the effect of the heavy metals as Hg, Cd, Zn and Tl on tomato growth is presented. More so, the mechanism by which heavy metals cause neurotoxicity, generate free radical which promotes oxidative stress damaging lipids, proteins and DNA molecules and how these free radicals propagate carcinogenesis are discussed. Net photosynthesis, transpiration and toxic metal ion concentration of leaf material and total plant biomass was measured. [/ICCBased 11 0 R] Get this from a library!

Some water plants can remove contaminating heavy metals from aquatic environments. Toxicity of heavy metal is a wide spread environmental problem affecting all life forms including plants. The resultsrevealed that heavy metals brought about significant reductionsin both parameters, Cd being the most toxic metal followed by Cu,Ni, Zn, Pb and Cr. These toxic effects (both direct and indirect) lead to a decrease in plant growth which finally results in the death of plant [15]. (2)Department of … Heavy metals show negative effects on plants.

The threshold level at 10 ppm for Ni and 50 ppm for Co has been proved undamaging for chickpea (Table 2; Figure 1). Heavy metal polluted soils leads to reduction in growth due to changes in physiological and biochemical activities. [/ICCBased 9 0 R] The influence of heavy metal addition on total, bacterial, and fungal activities was therefore studied for up to 60 days in a laboratory experiment using forest soil contaminated with different concentrations of Zn or Cu. The effect of heavy metal toxicity on the growth and development of plants differs according to the particular heavy Heavy metal toxicity to plants and low metal bioavailability in soil decreases the efficiency of phytoremediation. Concentration of all heavy metals in different parts of different vegetable plants is tabulated in Table 5. Heavy metals show negative effects on plants. Uptake of heavy metals by plants and subsequent accumulation along the food chain is a potential threat to animal and human health. Heavy-metal-contaminated soils impose various adverse effects on plant growth, such as plant macronutrient reduction, toxic concentrations of heavy metals, salinity, alkalinity, and poor physical structures (Bradshaw and Chadwick, 1982).

Heavy metal is a term used to describe more than a dozen elements that are metals or metalloids. Absorption and accumulation of metals in plant depend on many factors, such as pH, EC, clay content, organic matter content and physical and mechanical characteristics of soil. It is reported that phytoremediation technology is an alternative to treat heavy-metal-contaminated side which will be more admitted in order to remediate the environment. 2.4 Effect of Waste Water on the Heavy Metals Uptake in Plants 20 2.5 Effect of Heavy Metals on the Uptake of Minerals and Plant Growth 23 2.6 Nutritional Value of Vegetables and Fruits 25 2.7 Chilli (Capsicum) and Health Benefits 26 . In this paper the phytotoxic effects of heavy metals, Cr (VI) and Cd (II) on plants germination and growth were studied. Heavy metals are defined as metals having a density higher than 5 g/cm3.

The four heavy metals were changed in successive experiments such that each was replicated three times and each pair repeated twice. Plants resist heavy metal effects by producing metal binding proteins, the storage of heavy metals in trichomes of epidermis and increase in anti-oxidation enzyme activities. Heavy-metal-induced chlorosis is generally correlated with low plant Fe contents, suggesting effects of heavy metals on Fe mobilization and uptake. Beneficial heavy metals at high level could upsets the soil environment that consecutively adversely influences soil fertility, plant growth and development (Reeves and Baker, 2000). Effect of Heavy Metal Polluted Soil on Plant Growth. The impact of the heavy metals on aquatic organisms is due to the movements of pollutants from various diffuse or point The most generalized effect of heavy metals in plants is their attack to the photosynthetic apparatus. EFFECT OF HEAVY METALS ON PLANTS 119 more in corn. Heavy-metal content in Azolla, as affected hy the dilution of the nutrient medium. This detrimental effect varies with the nature of an element as well as plant species. It also alters the composition and activity of soil microbial communities. Heavy metal pollution is a serious global environmental problem as it adversely affects plant growth and genetic variation. Heavy metal pollution can result in adverse effects on plant growth, soil microbial diversity and activity, and apparently has a stronger impact on the genetic structure. The toxicity of heavy metals can be removed bioremediation or phytoremediation. endstream The heavy metal concentrations in above-ground tissue of Brassica juncea indicated a possible accumulation of heavy metals due to plant uptake by the high levels of Cu, Pb and Zn in soil. 2. In other words, antagonistic and synergistic behaviours exist among heavy metals. Alongside these mechanisms, the noxious health effects of these heavy metals are discussed.
