Comparative carcinogenic effects of nickel subsulfide, nickel oxide, or nickel sulfate hexahydrate chronic exposures in the lung.
The relative toxicity and carcinogenicity of nickel sulfate hexahydrate (NiSO4.6H2O), nickel subsulfide (Ni3S2), and nickel oxide (NiO) were studied in F344/N rats and B6C3F1 mice after inhalation exposure for 6 h/day, 5 days/week for 2 years. Nickel subsulfide (0.15 and 1 mg/m3) and nickel oxide (1.25 and 2.5 mg/m3) caused an exposure-related increased incidence of alveolar/bronchiolar neoplas...
متن کاملPreparation of Nickel Ferrite from thermolysis of Nickel Hexa(Formato)-Ferrate(III)Hexahydrate
Thermal decomposition of nickel hexa(format0) fetrate(DQ decahydrate i.e. Ni3ve(HC00)s]2. 10H,O has been studied upto 913 K in static air atmosphere employing TG,DTG,DTApSC,XRD$!SR, Mossbauer and f i r e d spectroscopic techniques. Dehydration occurs in two stages in the temperature range of 348-423 K. Immediately &r the removal of the last water molecule, the anhydrous complex undergoes decomp...
متن کاملTemperature Dependence Studies of 3 CI NQR Frequencies in Magnesium and Nickel Hexachlorotellurate(IV) Hexahydrates and Nickel Hexachloroiridate(IV) Hexahydrate*
The C1 NQR frequencies in MgTeCl6 • 6 H 2 0 , NiTeCl6 • 6 H 2 0 , and NiIrCl6 • 6 H 2 0 have been determined at various temperatures. These compounds form rhombohedral crystals with the space group R3, showing a single resonance line. The C1 NQR frequencies of the Te(IV) complexes exhibit an unusual positive temperature coefficient. The deuterated analogs of the Te(IV) complexes show a small fr...
متن کاملBis(triethanolamine)nickel(II) sulfate
The title compound, [Ni(C(6)H(15)NO(3))(2)]SO(4), contains two triethano-lamine (TEA) ligands bound to an Ni(2+) metal centre, which lies on a crystallographic inversion centre, and one sulfate anion located on a twofold rotation axis such that the asymmetric unit contains one-half molecule of the cation and of the anion. The triethano-lamine ligands coordinate via each axial N atom and two of ...
