Cadmium, nickel, arsenic, cobalt and lead strongly activated the transcription of the reporter gene, while zinc and iron had no impact. The AtMRP3 promoter thus seems to be a useful new tool in designing plants that can be used for biomonitoring of environmental contaminations.

From the cadmium raffinate, extraction of cobalt and nickel as a function of equilibrium pH in the range 5.4–7.0 was carried out at unit phase ratio using 0.01 and 0.03 M Cyanex 272 (Fig. 3). Percentage extraction of Co increased with increase in the pH of the aqueous phase.

Four MCE filters were spiked with soluble salts of the analytes at each concentration. The average digestion efficiency was 97.6% for arsenic, 103% for cadmium, 97.4% for cobalt, 99.1% for copper, 104% for lead, and 99.4% for nickel. (Section 4.8.1)

The objective of this research is to investigate a novel hydrometallurgical route to recover cadmium, cobalt and nickel from hydrochloric acid leachates of spent …

Cadmium, nickel, arsenic, cobalt and lead strongly activated the transcription of the reporter gene, while zinc and iron had no impact. The AtMRP3 promoter thus seems to be a useful new tool in designing plants that can be used for biomonitoring of environmental contaminations.

In contrast to cadmium, copper, zinc, and nickel, cobalt showed a clear increase in the surface water. The profile in Fig. 6b shows a representative picture of the cobalt distri- bution. In the surface water down to 500 m the average con- centration found is 33 pM and for the deep water (>500 m), 26 pM for all stations.

The nickel-cobalt-cadmium resistance genes carried by plasmid pTOM9 of Alcaligenes xylosoxidans 31A are located on a 14.5-kb BamHI fragment. By random Tn5 insertion mutagenesis, the fragment was shown to contain two distinct nickel resistance loci, ncc and nre. The ncc locus causes a high-level combined nickel, cobalt, and cadmium …

The transition metals nickel (Ni), chromium (Cr) and cobalt (Co) are common causes of allergic contact dermatitis (ACD). Given the high frequency with which these allergens can be associated with hand eczema in those responsible for domestic work, it has been suggested that contamination of consumer products with these …

Two of the most commonly-used types of batteries, Nickel Cobalt Aluminium (NCA) and Nickel Manganese Cobalt (NMC) use 80% and 33% nickel respectively; newer …

The wall-less strain of Chlamydomonas reinhardtii was consistently more sensitive than the walled strain to all four metals, indicating that the cell wall plays a role in conferring metal tolerance. Comparative studies of the toxicity of Cd, Co, Cu, and Ni to walled (UTCC 11) and wall-less (UTCC 12) strains of Chlamydomonas reinhardtii were …

copper (Cu), nickel (Ni), cobalt (Co), cadmium (Cd), and manganese (Mn), among others, have garnered attention for their biological utilization by phytoplankton and have been studied to determine the influence they exert on primary production in the oceans (Sunda 1989; Bruland et al. 1991; Morel and Price 2003; Twining and Baines 2013).

Risk assessment is the key process for environmental management and remediation of soil contamination. Metals, such as beryllium (Be), cadmium (Cd), nickel (Ni), and cobalt (Co) are considered important soil contaminants and environmental challenges, which cause a potential risk of harm to human health through inhalation …

Rhizopus stolonifer and Cunninghamella blakesleeana trained after five passages to tolerate elevated concentrations of copper simultaneously acquired a tolerance to elevated levels of cadmium, cobalt, nickel, and lead. The acquired tolerance to copper was not stable in the absence of the metal, as serial transfers to a copper-free medium …

A Metrosep C4-250/4.0 column was used for cobalt, nickel and the exchanged sodium Na + ions analysis and the mobile p hase was a mixture of Nitr ic ac id (0.9 mM) a nd

Photocatalytic water splitting for hydrogen evolution is one of the most promising methods to mitigate environmental and energy-related issues. In this study, manganese cadmium sulfide (Mn x Cd 1-x S) solid solution is used to construct a p–n heterostructure with NiCo 2 O 4 through a hydrothermal method.

Nickel-cadmium (Ni-Cd) batteries have high power and energy density, high efficiency of charge/discharge, and a low cycle life ( Table 2 ). The primary demerit of Ni-Cd batteries is a relatively high cost because the manufacturing process is expensive. In contrast, Cadmium is a toxic-heavy metal, hence posing issues associated with the disposal ...

A new solvent‐extraction process for the separation of cadmium, cobalt, and nickel in sulphate solutions coming from the hydrometallurgical processing of spent Ni‐Cd batteries is proposed. The main innovation is to use nickel salts of the extractants, thus avoiding external pH control in the extraction operation. The extractants are first …

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 ...

Heavy metals such as lead (Pb), nickel (Ni), chromium (Cr), cobalt (Co), copper (Cu), and cadmium (Cd) are exported at greater levels. Untreated wastes generated as a result of production processes have detrimental causes on the environment (Gavrilescu 2004 ; Chandra and Kumar 2017a ; Kumar et al. 2021a ).
