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.
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.
Cadmium concentrations in plant tissues were determined by flame atomic absorption spectrophotometry (Hitachi Z-81001, Hitachi Ltd., Hitachi, Japan) with the method detection limit (0.002 mg L −1 Cd). To ensure accuracy and precision with experimental errors ( 5%), quality control of the analytical method was conducted on ten samples at a ...
concentration of Cd and Zn in plant tissues, as well as in the amounts of Cd and Zn extracted by diethylene triamine penta-acetic acid–triethanol amine (DTPA–TEA). Significant inhibitory effects of Zn on Cd concentration in the leaves occurred at levels above 5 mg Zn kg-1 soil. Zinc concentrations in the leaves decreased, while those in the ...

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).
Jun 29, 2004 Seasonal concentrations of cadmium and zinc in native pasture plants: consequences for grazing animals. Brekken A(1), Steinnes E. ... The two metals correlated in the material as a whole, but the concentration variations were most pronounced for Cd. There were also seasonal variations (generally a concentration reduction during spring).

tion in fuels, ore dumps, and fertilizers are responsible for the increasing concentration of this metal in the environment. In this regard, control over the cadmium content in natural and economic facilities and soil and water purification from its compounds are topical environmental issues. Currently, phytoremediation, i.e., the use of plants for
Feb 27, 2012 Cadmium (Cd) is a toxic heavy metal and is also known as one of the major environmental pollutants. Moderate Cd contamination of arable soils can result in considerable Cd accumulation in edible parts of crops (Arao and Ae 2003; Arao et al. 2003; Wolnik et al. 1983).Such levels of Cd in plants are not toxic to crops but can contribute to substantial Cd dietary intake by humans …
Cadmium is one of the most dangerous metals due to its high mobility and the small concentration at which its effects on plants begin to appear (Barcel and Poschenrieder, 1990). The apoplast continuum of the root epidermis and cortex is readily permeable for solutes.
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) is a toxic heavy metal that enters the environment through various anthropogenic sources, and inhibits plant growth and development. Cadmium toxicity may result from disturbance in plant metabolism as a consequence of disturbance in the uptake and translocation of mineral nutrients. Plant nutrients and Cd compete for the same transporters and, therefore, presence of Cd results in ...
One of the main daily consumer products in Peru is potato, but in recent years, the addition of agrochemicals with possible heavy metal content, such as cadmium (Cd) has decreased the quality of the final product resulting in a negative impact on soils. The objective of this study is to determine the concentration of Cd in cultivation areas and in potato plantations. For this purpose, 6 tuber ...
Heavy metals, such as cadmium, copper, lead, chromium, manganese, iron ... It toxicity in plants varies with plant species, specific metal, concentration, chemical form and soil composition and pH, as many heavy metals are considered to be essential for plant growth. Some of these heavy metals like Cu and
Cadmium metal (Cd 2+) refined from the ore is a silver-white, blue-tinged lustrous heavy metal solid at room temperature. Global cadmium production almost doubled between 1950 and 1990. Since 1990, global consumption has remained constant, at about 20,000 tons per year, although major changes have occurred in its geographical distribution.
