The adsorption of Zn 2+, Pb 2+, Cu 2+, Co 2+, and Cd 2+ (M 2+) by soils was measured at concentrations ranging from 10-7 to 10-2 M in 10-3 to 10-2 M CaCI 2.Exchange between Ca 2+ and M 2+, and solubility products [M 2+][OH −] 2 indicate that M 2+ is not precipitated as hydroxide but is adsorbed on cation-exchange sites. The proportion of selective …
Early toxic effects of heavy metals (HMs) Zn, Co, and Cd at concentrations from 0.01 to 100 mM on photosynthetic activity of the green algaChlorella pyrenoidosaChick S-39 were studied. The early effect of HMs was manifested as a rapid (within 0.5–2 h) reduction of photoinduced oxygen release by the algal cells. The suppressed relative …
BACKGROUND AND AIMS The uptake, translocation and redistribution of the heavy metals zinc, manganese, nickel, cobalt and cadmium are relevant for plant nutrition as well as for the quality of harvested plant products. The long-distance transport of these heavy metals within the root system and the release to the shoot in young wheat (Triticum ...

Activity of the AtMRP3 promoter in transgenic Arabidopsis thaliana and Nicotiana tabacum plants is increased by cadmium, nickel, arsenic, cobalt and lead but not by zinc and iron Author links open overlay panel Katarzyna Zientara a, Anna Wawrzyńska a, Jolanta Łukomska a, José Rafael López-Moya a 1, Frantz Liszewska a …
The promoter induces GUS activity in the roots as well as in the shoots upon metal exposure. Similar responses of the AtMRP3 promoter to the presence of the selected metals was observed in both plant species. Cadmium, nickel, arsenic, cobalt and lead strongly activated the transcription of the reporter gene, while zinc and iron had no impact.
The P(1B)-type heavy metal ATPases (HMAs) are diverse in terms of tissue distribution, subcellular localization, and metal specificity. Functional studies of HMAs have shown that these transporters can be divided into two subgroups based on their metal-substrate specificity: a copper (Cu)/silver (Ag) group and a zinc (Zn)/cobalt (Co)/cadmium …
Coagulation using aluminium and iron salts is very effective for removing silver, chromium (III) and tin; lead, vanadium and mercury levels are reduced by between 50 and 90%; copper (in some cases), cadmium, zinc, nickel and barium are not effectively removed. Cobalt, molybdenum and chromium (VI) are not reduced at all.
This work efficiently removes cobalt from the zinc plant residue using sodium persulfate as an oxidizing agent. • The utilization of sodium persulfate as an oxidizing agent to recover high-grade cobalt as Co 3 O 4 is a new concept.. This work is original and performed at the lab scale with a proper elemental balance and a flowsheet which can …
Cobalt (Co) is not stated as an essential microelement for plants, but it is considered beneficial for particular plant taxa owing to its role in physio-biochemical processes. Lower levels of Co as beneficial element received less attention in recent decades than phytotoxic effects at higher concentrations.
A large amount of hot filter cake (HFC) is annually generated in Iranian zinc plants. It contains 1% zinc, 16–30% manganese, 5–25% calcium and 1–4.5% cobalt. Usually, zinc is selectively leached by an alkaline medium and its residue is known as alkaline leached HFC (ALHFC). In the present study, the possibility of cobalt extraction …
Cadmium (Cd+2) renders multifarious environmental stresses and highly toxic to nearly all living organisms including plants. Cd causes toxicity by unnecessary augmentation of ROS that targets essential molecules and fundamental processes in plants. In response, plants outfitted a repertory of mechanisms to offset Cd toxicity. The …
Zinc plays many essential roles in life. As a strong acid that lacks redox activity under environmental and cellular conditions, the Zn 2+ cation is central in determining protein structure and catalytic function of nearly 10% of most eukaryotic proteomes. While specific functions of zinc have been elucidated at a molecular level in …

1. Introduction. Cadmium (Cd) is toxic to organisms in the ecosystem as a nonessential heavy metal. Cd is mainly released into the soil and water body by natural and anthropogenic sources, like mining, application of Cd-containing fertilizers, sewage sludge [1], [2].Excessive amount accumulation of Cd in plants not only affects normal growth …

Abstract The phloem mobility of heavy metals is relevant to the redistribution of micronutrients and pollutants and, ultimately, to the quality of harvested plant parts. The relative mobility in wheat may vary considerably between different cations. In the study reported here, radio-labeled nickel (Ni), cobalt (Co), manganese (Mn), zinc (Zn) and …
Long‐term transformation pathways, kinetics and lability of cadmium (Cd), cobalt (Co), copper (Cu), nickel (Ni), zinc (Zn), manganese (Mn), and iron (Fe) in two arid‐zone soils were studied under saturated water regime (simulating the moisture regime in the soil during the raining season and shortly after irrigation) by using operationally ...
