  • Cadmium in Plants USGS

    The mean cadmium concentration in the ash of "surface" plants was reported by Malyuga (1964, p. 15) to be 1 10" percent (0.01 ppm). This value seems to be much too low for cadmium in plant ash but would be a reasonable value (although still low) for the concentration of cadmium in the dry plant

    these trace elements have the potential to accumulate in plants, animals, other living organisms and soil. Even a minimal concentration of some trace element ions like cadmium (Cd), lead (Pb) and arsenic (As) is toxic to living organisms (Mendil and Tuzen 2011). Trace elements accumulation in plants

  • Shoot cadmium concentration of soil‐grown plants as

    Cadmium (Cd) is toxic to plants, animals, and humans. However, different plant species growing on the same soil may have very different shoot Cd concentrations depending on properties such as size of the root system, Cd net influx, shoot‐growth rate, Cd translocation from root to shoot, and the ability to affect Cd availability in the soil.

  • Cadmium Toxicity and Tolerance in Plants ScienceDirect

    Some plants can tolerate a small concentration of Cd, while some show changes in their phenotype, such as a decrease in weight, roots, and shoot lengths. Cytotoxicity, inflammation, and deterioration have also been observed in plants due to Cd toxicity. Different types of food may have different levels of cadmium, such as green leafy vegetables

  • Cadmium in plants and soil

    If the concentration of cadmium in your soil is greater than 20 mg/kg If soil cadmium levels are elevated, grow plant varieties that take up less cadmium; Leafy vegetables like lettuce, cabbage and spinach take up the most cadmium. Root crops such as carrots and potatoes take up less but fruiting plants take up the least amount of cadmium.

    Effect of cadmium on the plant growth: Cadmium is not an essential nutrient and at high concentration inhibits plant growth (Anita et al ., 1990; Aery and Rana, 2003).

  • Chapter 6.3 Cadmium World Health Organization

    Cadmium in food comes to a large extent from atmospheric cadmium as a result of foliar absorption or root uptake of cadmium deposited on soils. Foliar absorption is determined by dry or wet deposition rates of cadmium and uptake of cadmium by plants from soils is primarily controlled by the concentration of cadmium in soil solution.

  • Cadmium (Cd) Toxicity: Where is Cadmium Found? ATSDR

    May 12, 2008· Most cadmium ore (greenockite): exists as cadmium sulfide, is refined during zinc production, and; occurs in association with zinc. It is released into the environment through mining and smelting, its use in various industrial processes, and enters the food chain from uptake by plants from contaminated soil or water. Sources of Cadmium

  • Selection and breeding of plant cultivars to minimize

    Feb 15, 2008· The low-Cd trait was highly heritable so selection on a single plant basis was feasible. Cadmium concentration of leaf tissue was highly correlated with grain Cd concentration (r = 0.87 to 0.89) and therefore could predict the plant phenotype, which would be useful in backcrossing the low-Cd trait into high-Cd cultivars (Clarke et al., 1997b).

    Objective: To discuss the effect of cadmium concentration on the plant growth and the cadmium absorption and accumulation of Ocimum basilicum. Method: With O. basilicum as the plant materials, effects of cadmium concentration on the plant growth, cadmium accumulation, soluble sugar content, total N, P and K contents were studied on the basis of Hoagland nutrition.
