- Type: Interview / Questionnaire / Record review / Work history / Clinical tests / other: lung specimens, Employment records, medical files
- Details: lung specimens collected from 39 consecutive autopsies between 1978 and 1984. Control lung tissue was also obtained from 16 autopsied persons not connected with the refinery. Tissue was collected from the right lower lobe and place in formaldehyde with Na2HPO4. Medical files were used to determine cause and age of death as well as smoking information.
-Other: specimens from the center and periphery of each lobe were collected from a worker (not included in the 39) and analyzed to determine variations in nickel concentration in different regions of the lung.
STUDY PERIOD: workers autopsied between 1978 and 1984
SETTING: Nickel refinery in Kristiansand, Norway
STUDY POPULATION

- Selection criteria: nickel refinery worker
- Total number of subjects participating in study: 39
- Sex/age/race: average age of death was 66+/- 8 years; for workers with carcinomas 64 +/- 8.
- Smoker/nonsmoker: 23 cigarette smokers, 11 other smokers (<10 cigarettes daily, former smokers, pipe smokers), 5 non-smokers
- Other: average age at start of employment for all workers was 39 +/- 11 years, for those with carcinomas of the lung 38 +/- 8 years
COMPARISON POPULATION
- Type: State registry / Regional registry / National registry / Control or reference group / Other comparison group: other

HEALTH EFFECTS STUDIED
- Disease(s): lung cancer
- Other health effects: other causes of death reported but not statistically evaluated included nose, colon, kidney and malignant melanoma cancers
OTHER DESCRIPTIVE INFORMATION ABOUT STUDY:
-lung samples were analyzed for total nickel using Electrothermal Atomic Absorption Spectrometery - Exposure assessment:
- not specified
- Details on exposure:
- DESCRIPTION / DELINEATION OF EXPOSURE GROUPS / CATEGORIES:TYPE OF EXPOSURE:
-15 workers were employed in the Roasting and Smelting Department where exposure to nickel was predominantly in the form of nickel-copper oxides, Ni3S2 and metallic dust
- 24 workers were employed in the Electrolysis Department where exposure was considered to be mostly to the water-soluble compounds, NiS04 and NiCl2, but also to a lesser degree to water-insoluble nickel compounds such as nickel-copper oxides and sulphides - Statistical methods:
- Means of lung nickel concentrations were tested to see if levels differed at the 1% (P=O.Ol) or 5% (P =0.05) level of significance employing a one-way analysis of variance (the F-statistic). Sampled populations were also tested against each other with Duncan's New Multiple Range Test with unequal observations. To meet the conditions of normal distributions and comparable population variances, all statistical comparisons involved logarithms of the nickel concentrations.
Results and discussion
- Results:
- EXPOSURE (Lung tissue measurements)
Roast and Smelting Department (n=15)
-Arithmetic mean ± SD: 333 ± 382 µg/g dry weight
-Geometric mean: 148 µg/g dry weight with 99% CLs of 45-490 µg/g dry weight
Electrolysis Department (n=24)
-Arithmetic mean ± SD: 34 ± 48 µg/g dry weight
-Geometric mean: 16 µg/g dry weight, with 99% CLs of 8-34 microgram per gram dry weight
Reference Group (n=16)
-Arithmetic mean ± SD: 0.76 ± 0.39 µg/g dry weight
Geometric mean: 0.67 µg/g dry weight, with 99% CLs of 0.48-0.95 µg/g dry weight
INCIDENCE / CASES OF LUNG CANCER
-Roasting and Smelting Department: lung cancer present in 8 of 24 workers; F-statistic = 0.50 (not significant)
-Electrolysis Department: lung cancer present in 6 of 15 workers; F-statistic = 0.11 (not significant)
-All Workers: lung cancer present in 14 of 39 workers; F-statistic = 0.66 (not significant)
OTHER OBSERVATIONS:
-No trend observed between lung nickel content in relation to the time elapsed between retirement and death
-Lung nickel concentrations did not show any dependence on smoking habits
-One-way ANOVA showed that mean nickel concentrations in lung tissue were statistically significantly different between the three groups. - Confounding factors:
- -Lung nickel concentrations did not show any dependence on smoking habits
- Strengths and weaknesses:
The authors discussed the potential losses of nickel from the tissues during the storage in 4% formaldehyde and the washing protocol (dipping into deionized water), but concluded that good agreement between this study and a previous study was an indication that the loss to the storage medium is minimal.

Applicant's summary and conclusion
- Conclusions:
- The authors concluded that (1) nickel refinery workers exhibit elevated nickel levels in lung tissues at autopsy; (2) workers of the Electrolysis Department and the Roasting and Smelting Department constitute distinct groups with respect to the accumulation of nickel in lung tissue; (3) workers who were diagnosed to have lung cancer had the same lung nickel concentrations at autopsy as those who died of other causes.
The authors also concluded that their data show that pulmonary tissue nickel concentrations may not be used as a definitive etiologic criterion, but that this did not constitute a rejection of a causal relationship between exposure to nickel compounds and respiratory cancers. It was also concluded that in addition to primary exposure to soluble nickel salts, Electrolysis Workers were also exposed to insoluble forms of nickel. - Executive summary:
Andersen and Svenes (1989) reported on the concentrations of nickel in lung tissue collected from refinery workers. The objective of evaluating the concentrations of nickel in the lung specimens was two-fold: (a) measurements would help to clarify the uncertainty in exposure histories to various types of nickel within the refinery, and (b) comparison of tissue concentrations would characterize the levels in workers with and without lung cancer. Lung tissue samples were collected from autopsied workers in the Roasting and Smelting Department (n=15), Electrolysis Department (n = 24), as well as from persons not connected with the refinery (n=16); concentrations of total nickel were determined using Electrothermal Atomic Absorption Spectrometry. Though workplace exposures were not measured in this study, the authors stated that exposure to nickel was predominantly in the form of nickel-copper oxides, Ni3S2, and metallic dust in the Roasting and Smelting Department, whereas in the Electrolysis Department, exposures were to mostly to water soluble compounds (NiSO4 and NiCl2), but also to a lesser degree to water insoluble nickel compounds such as nickel-copper oxides and sulphides. Tissue concentrations were based on samples collected from the right lower lobe; however, additional samples (n=10) collected and analyzed from the center and periphery for each lobe indicated no differences between concentrations in the center and periphery segments.
Results of statistical analyses indicated that measured levels of nickel in the three groups were clearly different; 333 ± 382 μg/g (dry weight), 34 ± 48 μg/g, and 0.76 ± 0.39 μg/g in Roast and Smelting Department workers, Electrolysis Department workers, and the reference group, respectively. When tissue concentrations were compared between individuals diagnosed with lung cancer relative to those diagnosed with other diseases, no significant difference was found. Additionally, no trends between time elapsed between retirement and death, or smoking habits, were found. However, a relationship between the number of years worked and tissue nickel levels was noted. Based on these findings, the authors concluded employment at a nickel refinery resulted in increased tissue levels of nickel in the lung at autopsy, but that these levels did not correlate with the incidence of lung cancer in workers relative to those who died of other causes. Though nickel oxide was only one of many nickel compounds to which workers were exposed, this study clearly indicates that occupational exposure in an environment where nickel-copper oxides were present resulted in higher concentrations of nickel in the lungs relative to environments without such, but that in the study population evaluated, a correlation between lung cancer and tissue concentrations of nickel in the lung was not observed.
