The aim of this study was to measure the levels of nickel in the skin contaminant layer of workers involved in specific processes and tasks within the primary nickel production and primary nickel user industries. Dermal exposure samples were collected using moist wipes to recover surface contamination from defined areas of skin. These were analysed for soluble and insoluble nickel species. Pers...

Toxic trace metals can be hazardous even at very low concentrations. When they get into water supplies and aqueous environments the health of plants and animals, as well as humans, can be impaired. Toxic trace metals are commonly found in wastewater and removing them efficiently presents a unique challenge. The discharge of heavy metals into aquatic ecosystems has become a matter of concern in ...

The objective of the present investigation was to study the influence of the occupational nickel exposure on the concentration of nickel in nasal mucosa, plasma and urine. Plasma, urine and biopsy specimens of nasal mucosa from 318 nickel workers, 15 retired nickel workers and 57 non-exposed controls were analyzed for nickel by atomic absorption spectrometry. The results showed that nickel expo...

Rhizomucor tauricus is used in the production of lipase, after several cycles it is disposed off as biological waste. A new biosorbent material fungus, Rhizomucor tauricus was immobilized, used as an adsorbent for removal of Nickel (II) and for optimization Box-Behnken design used by statistica 6.0. The time required to reach equilibrium was found to be 4 hours. The optimized concentration is 6...

Although nickel is an essential element for animal nutrition, the physiological role of nickel is not yet established. Pathological alterations of nickel metabolism are recognized in several human diseases. The diverse clinical manifestations of nickel toxicology include: (1) acute pneumonitis from inhalation of nickel carbonyl, (2) chronic rhinitis and sinusitis from inhalation of nickel aeros...

Micellar enhanced ultrafiltration (MEUF) process has been used for the removal of copper, chromate, zinc, nickel, cadmium, serinium, arsenate and organics like phenol, o-cresol. This paper reviews various factors such as operating pressure, surfactant concentration, pH of solution, temperature, presence of non-ionic surfactant and salt, membrane type and its pore size and some inhibiting additi...

Key Points Fire  Elemental nickel dust and nickel carbonyl are flammable  Nickel is incompatible with acids, oxidizing agents and sulphur  Nickel and nickel carbonyl react violently with oxidants  Nickel and nickel compounds emit toxic fumes and vapours of nickel carbonyl when heated to decomposition  In the event of a fire involving nickel carbonyl, use fine water spray and gas tight kit ...

This study aims to synthesize magnetite by a co-precipitation method. The prepared adsorbent coated silica for the efficient removal nickel and manganese ions from aqueous solutions. samples have characterized several techniques like FTIR spectroscopy, XRD, TEM. Surface modification causes ability of removing metals increasing more than 98%. Preliminary results indicate that may be used as an w...
