“…Nickel is recognized as a potential human carcinogen [10, 11], can cause allergic reactions [12, 13], and can induce cancer in animals [13, 14]. Nickel in airborne PM is mainly derived from rock weathering and volcanic eruptions, but may also originate from combustion of oil additives and metallurgical processes [15, 16].…”

Previous studies have indicated Environmentally Persistent Free Radicals (EPFRs) are formed when hydroxyl- and chlorine-substituted aromatics chemisorbed on Cu(II)O and Fe(III)2O3 surfaces and were stabilized through their interactions with the surface metal cation. The current study reports our laboratory investigation on the formation and stabilization of EPFRs on an Ni(II)O surface. The EPFRs were produced by the chemisorption of adsorbates on the supported metal oxide surface and transfer of an electron from the adsorbate to the metal center, resulting in reduction of the metal cation. Depending on the temperature and the nature of the adsorbate, more than one type of organic radical was formed. A phenoxyl-type radical, with g-value between 2.0029 and 2.0044, and a semiquinone-type radical, with g-value from 2.0050 to as high as 2.0081, were observed. The half-lives on Ni(II)O were long and ranged from 1.5 to 5.2 days, which were similar to what were observed on Fe(III)2O3,. The yields of the EPFRs formed on Ni(II)O was ~ 8x higher than on Cu(II)O and ~50x higher than on Fe(III)2O3.

“…The 10-year average Ni concentration (5.9 ± 5.5 ng m −3 ) was well below the recommended level of 25 and 20 ng m −3 defined by WHO12 and European Union (EU)18, respectively. There is no Ni limit established in National Ambient Air Quality Standards (NAAQS) in China19.…”

“…Nickel tetracarbonyl, Ni(CO) 4 , has been found to be the most toxic, as reported the influences on industrial workers12. Exposure to Ni and its associated compounds can cause a variety of adverse effects on human health1314, among which the most important are developmental, genotoxic, neurological, reproductive, and carcinogenic12. Using the National Morbidity, Mortality, and Air Pollution Study database, Lippmann et al 15.…”

This study presents the first long term (10-year period, 2004–2013) datasets of PM2.5-bound nickel (Ni) concentration obtained from the daily sample in urban of Xi’an, Northwestern China. The Ni concentration trend, pollution sources, and the potential health risks associated to Ni were investigated. The Ni concentrations increased from 2004 to 2008, but then decreased due to coal consumption reduction, energy structure reconstruction, tighter emission rules and the improvement of the industrial and motor vehicle waste control techniques. With the comparison of distributions between workday and non-workday periods, the effectiveness of local and regional air pollution control policies and contributions of hypothetical Ni sources (industrial and automobile exhausts) were evaluated, demonstrating the health benefits to the populations during the ten years. Mean Ni cancer risk was higher than the threshold value of 10−6, suggesting that carcinogenic Ni still was a concern to the residents. Our findings conclude that there are still needs to establish more strict strategies and guidelines for atmospheric Ni in our living area, assisting to balance the relationship between economic growth and environmental conservation in China.

“…In complementary balance studies, they concluded that ∼90% of nickel ingested in the diet was excreted in faeces and 10% in urine. They commented that as nickel carbonyl is highly reactive in the presence of oxygen, there was a possibility that it might decompose to produce colloidal nickel on the pulmonary epithelium. (233) Sunderman and Selin (1968) followed the biokinetics of 63 Ni for 4 d after inhalation of 63 Ni(CO) 4 by rats. In complementary experiments, they followed the biokinetics of 63 Ni after intravenous injection of 63 Ni(CO) 4 and 63 Ni chloride ( 63 NiCl 2 ).…”
