Cadmium is a non-essential trace metal, which highly toxic to nearly all living organisms. Soil pollution causes Cd contamination of crops, thereby rendering plant products responsible for the chronic low level over-exposure numerous populations in world. For this reason, accumulation plants has been studied about five decades now. The research first focused on relationships between and soil levels, factors metal availability soil, as well root uptake processes. distribution organs was also...
Tracing the source of heavy metals in environment is key importance for our understanding their pollution and natural cycles surface Earth reservoirs. Up to now, most exclusively Pb isotopes were used effectively trace metal sources environment. Here we report systematic variations Cd isotope ratios measured polluted topsoils surrounding a Pb-Zn refinery plant northern France. Fractionated was soil samples refinery, this fractionation can be attributed refining processes. Despite isotopic...
Until now, there has been little data on the isotope fractionation of nickel (Ni) in higher plants and how this can be affected by plant Ni zinc (Zn) homeostasis. A hydroponic cultivation was conducted to investigate Zn during uptake translocation processes. The nonaccumulator Thlaspi arvense, hyperaccumulator Alyssum murale Noccaea caerulescens were grown low (2 μM) high (50 solutions. Results showed that inclined absorb light isotopes, presumably due functioning low-affinity transport...
Ag, As, Bi, Cd, Co, Cr, Cu, Hg, In, Ni, Pb, Sb, Se, Sn,Tl, Th, U and Zn contamination of cultivated surfacehorizons has been assessed around two lead zincsmelters in the North France. The verticaldistribution Sb Tl inthe soils also examined. thelead zinc smelter at Noyelles-Godault arecontaminated by Sb,Se, Sn, Zn. original concentration themost contaminated may be multiplied a factorof 2 to 100, according element. Cadmium,Pb are most abundant contaminants. Pband concentrations correlated...
Nickel, a potentially toxic metal, is present in all soils with an average concentration of 20 to 30 mg/kg, sometimes exceeding 10,000 mg/kg (e.g., ultramafic soils). The ecotoxicological risk Ni organisms controlled by its availability. It therefore essential identify efficient and reliable method for the evaluation this risk. This paper presents complete study effect origin, localization, soil properties on availability as assessed isotopic exchange kinetics (IEK) compares plant response...
Abstract Plant response to soil Cd is highly variable. Plants varying in accumulation pattern were evaluated determine if was taken up from similar or different pools soils. Three metal‐contaminated soils (pH 8) and noncontaminated labeled with 109 using a carrier‐free CdCl 2 solution. Rye grass ( Lolium perenne L.), lettuce Lactuca sativa the Zn‐ Cd‐hyperaccumulator Thlaspi caerulescens J. Presl & C. grown on these harvested. The isotopic composition of plant shoots (IC P ) measured...
