Characteristics of cadmium accumulation and tolerance in novel Cd-accumulating crops, Avena strigosa and Crotalaria juncea.
Characteristics of accumulation and tolerance of cadmium (Cd) in green manure crops were investigated to identify Cd-accumulating crops and to clarify the mechanisms involved in Cd accumulation and tolerance. Seedlings of eight crop species were treated with Cd (1 mg l(-1) or 5 mg l(-1)) in the growing medium for 4 d. Cd concentration in leaves of Avena strigosa Schreb. cv. New-oat, Crotalaria ...

23 The biogeochemistry and bioavailability of cadmium, released during sphalerite 24 weathering in soils, were investigated under contrasting agricultural scenarios to assess 25 health risks associated with sphalerite dust transport to productive soils from mining. 26
متن کاملinvestigation of cadmium uptake in root region and accumulation in different parts of common summer crops in iran
the main source of heavy metals in soil is the use of urban and industrial waste water, synthetic phosphate fertilizers, sludge from sewage treatment plants. most heavy metals accumulate in the top soil and in the long term, their increased concentration in the soil and accumulation in the plants. the quantity or level of absorption in plants, depends not only on the concentration levels of the...
متن کاملCadmium Levels in Soils and Crops in the United States
The concentrations of cadmium in agricultural soils depend upon the amounts present in the parent rocks from which the soils form, the amounts added in the form of fertilizers and soil amendments, the amounts deposited onto soils from the atmosphere, and the amounts removed by harvested crops and by leaching. On average, sedimentary rocks contain greater concentrations of Cd than either igneous...
متن کاملCadmium accumulation in aortas of smokers.
Abdominal aortic aneurysm is a smoking-related disorder. Cadmium, inhaled from cigarettes, may accumulate in the aorta and facilitate weakening of the aorta through adverse effects on smooth muscle cell metabolism. Cadmium was measured by atomic absorption spectrometry in infrarenal aortas from 13 patients with abdominal aortic aneurysm and from 17 age- and sex-matched patients with normal-diam...
