Turkey's Lineer Metal has decided to establish a zinc metal production facility with an initial capacity of 30,000 tonnes/year in Siirt Organized Industrial Zone. By-products from the facility will be pushed to the battery materials sector, Kallanish understands. The integrated facility, which will be established by a Turkish-Qatar ...

The extent of plant injury by elevated Zn concentrations is also assessed, considering its specific and strong dependence on the environmental conditions and availability of other heavy metals.

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 opposite situation was observed for lead and copper. Soil supplementation with cadmium and zinc affects manganese, lead and copper concentrations and photosynthesis intensity in lemon balm plant.

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.

The melting (321) and boiling sity >5 g/cm3) zinc, cobalt, cadmium, and (766 ) points of cadmium are even lower nickel are used in industrial countries for a than the respective values for zinc; plants variety of applications.

The mechanisms of cadmium, cobalt and zinc resistance were characterized in the plant-growth-promoting bacterium Gluconacetobacter diazotrophicus PAl 5.

• 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.

Exposure and Health (2024) Cadmium (Cd) is an important environmental pollutant and long-term Cd exposure is closely related to autoimmune diseases, cancer, cardiovascular diseases (CVD), and ...

In the present study, a method for cobalt recovery from Zinc Plant Residue (ZPR) has been developed. First, the residue was leached in a dilute sulphuric acid solution. More than 90% cobalt and 95% zinc were leached in two hours at room temperature. Then, leach liquor was purified before cobalt precipitation. First, copper and cadmium …

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 from ALHFC was investigated using a creative hydrometallurgical process. At the first stage, zinc and cadmium were selectively removed with sulfuric acid.

The divalent cations of cobalt, zinc, and nickel are essential nutrients for bacteria, required as trace elements at nanomolar concentrations. However, at micro- or millimolar concentrations, Co2+, Zn2+, and Ni2+ (and "bad ions" without nutritional roles such as Cd2+) are toxic. These cations are tr …

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 ...

The beneficial effects of cobalt include retardation of senescence of leaf, increase in drought resistance in seeds, regulation of alkaloid accumulation in medicinal plants, and inhibition of ethylene biosynthesis. In lower plants, cobalt tolerance involves a cotolerance mechanism. The mechanism of resistance to toxic concentration of cobalt ...

In the study reported here, radio-labeled nickel (Ni), cobalt (Co), manganese (Mn), zinc (Zn) and cadmium (Cd) were introduced into either intact young …

The increase in the high concentration of cadmium and zinc in water and soil sources is due to the combination of minerals with air and the release of metals 7, 8.

• 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 ( …

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 …

The long-distance transport of these heavy metals within the root system and the release to the shoot in young wheat (Triticum aestivum …

The conventional roast-leach zinc extraction process yields a solid residue consisting of a mixture of zinc, copper, cadmium, and cobalt. Some zinc smelting plants process that residue [1] [2] [3 ...

The P 1B -type ATPases, known as heavy metal ATPases (HMAs), play an important role in metal transport in plants. Functional studies on the HMAs have shown these transporters to be divided into two subgroups based on their metal-substrate specificity: a copper (Cu)/silver (Ag) group and a zinc (Zn)/cobalt (Co)/Cd/lead (Pb) …

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. Plants accumulate Co (mainly …
