Cadmium in Plants By HANSFORD T. SHACKLETTE CONTRIBUTIONS TO GEOCHEMISTRY GEOLOGICAL SURVEY BULLETIN 1314-G An account of the concentrations of cadmiumCadmium uptake and partitioning in durum,Concentrations of cadmium (Cd) in the grain of many durum wheats (Triticum turgidum subsp. durum) grown in North American prairieJournal of Environmental Quality Abstract,Cabbage, the most tolerant plant species tested, showed 50% growth reduction at Cd solution concentrations of 9 µg/ml. Cadmium concentrations of plant leaves increased as the amount of Cd added to the substrate solution increased.

Cadmium is a toxic element used in the manufacture of batteries and is found in cigarette smoke, some paints, soil zinc additives, some fertilisers (especially those that contain phosphorus) and some manures. Industrial activity, such as mining, can increase soil cadmium levels.Effects of nanomolar cadmium concentrations on water,,Effects of nanomolar cadmium concentrations on water plants – comparison of biochemical and biophysical mechanisms of toxicity under environmentally,

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 concentration averaged 0.077 mg kg − 1 for Arcola, 0.157 for Kyle, 0.038 for Genesis and 0.055 for Katepwa. While there was a three-fold range in Cd concentrations with location, the cultivar ranking was maintained across locations.Effect of cadmium on growth, micronutrient,Cadmium concentration and plant tolerance to Cd: Our data demonstrate that higher metal exposures led to remarkable Cd accumulation in both root and shoot tissues, hence leading to a high degree of toxicity, which is in agreement with results reported by other authors (e.g., Carneiro et al., 2002; Lima et al., 2006; Mishra et al. 2006).All the information on Cadmium - Level of,Three distinct categories may be recognised with respect to cadmium-in-air concentrations,then eventually transferred to plants and animals,,

Cadmium absorption and transportation pathways in plants,such as cadmium, plant roots must avoid the uptake of harmful or,[Taylor & Francis,Cadmium - Wikipedia,The average concentration of cadmium in Earth's crust is between 0.1 and 0.5 parts per million (ppm). It was discovered in 1817 simultaneously by Stromeyer and Hermann, both in Germany, as an impurity in zinc carbonate. Cadmium occurs as a minor component in most zinc ores and is a byproduct of zinc production.Effects of nanomolar cadmium concentrations,At low Cd concentrations, Zn was found mainly in the epidermis and in the mesophyll. At moderately toxic Cd concentration (20 nM), a higher proportion of Zn was found in the mesophyll. At the highest Cd concentrations, Zn was seemingly stuck in the vein, suggesting that the Zn-exporters were blocked by Cd.
The effect of compost and humic acid in mobility and concentration of cadmium and chromium in contaminated soil were investigated. Experiment was carried out with three levels of soil cadmium and chromium and two organic matters (compost and humic acid). The study was performed in a randomized complete block design with 3 replicates.Ecological Soil Screening Levels for Cadmium - US EPA,Ecological Soil Screening Levels for Cadmium,Ecological Soil Screening Levels,The most important soil factors influencing plant cadmium,Effects of Ammonium Chloride Fertilizer and its,,Grain Cd concentration in wheat fertilized with NH 4 Cl at the tillering–jointing and flowering stages in the field experiment was 0.223 mg kg –1, which was about 1.5
