Chromosomal aberrations were studied in Chinese hamster ovary cells and in Oil Id I ' cells following treatment with NiO:, crystalline NiS, and CaCrO«.All three compounds caused an increase in chromosomal aberrations in a concentrationand time-dependent fashion. The chro mosomal aberrations induced by NUI., and crystalline NiS occurred predominantly in heterochromatic regions of the chromosome...

To avoid the toxic effect of released nickel ions and compounds from conventional stainless steels, nickel-free austenitic stainless steels have been developed. We previously established a new manufacturing process to produce nickel-free austenitic stainless steel that involves nitrogen adsorption treatment. Although the cytocompatibility of nickelfree austenitic stainless steel produced using ...

Industrial development and extensive use of heavy metals have led to the problem of environmental pollution. Nickel compounds are toxic to plants and have detrimental effects on their growth. Valerian is a plant used in herbal medicine. Considering the hazards of nickel, various methods have been developed to remove this contaminant from herbs irrigation wastewater, including the common chemica...
