Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Type of population:
- Number of subjects exposed: 14 men and 12 women (12 male and 12 female age-matched controls)
- Sex: 14 men and 12 women
- Age: 26-64
- Race: not reported
- Demographic information: workers from a chemical plant
- Known diseases: not reported
- Other: 6 men and 4 women known smokers
- Other: exposure duration 25 yrs (ave. men) and 15 yrs (ave. women)
Ethical approval:
not specified
Route of exposure:
Reason of exposure:
unintentional, occupational
Exposure assessment:
Details on exposure:
Exposed to Ni aerosols. Airborne nickel concentrations measured at the end of shift and analyzed by AAS. In the chemical plant the workers were exposed to high concentrations of nickel which exceeded 4-26 times the threshold limit values (TLV) of 0.05 mg/m3.
- Urine analysis: measures include: total proteins, LDH, lysozyme, B2-m, albumin, NAG, RBP, and transferin.
Medical treatment:
none reported

Results and discussion

Clinical signs:
none reported
Results of examinations:
The concentration of nickel in the urine from male and female workers averaged 5.0 and 10.3 ug/g creatinine. No difference was found in the mean urinary excretion of lactate dehydrogenase, albumin and transferrin in both sexes, total proteins, b2-microglobulin (b2-m) and retinol-binding protein (RBP) in males and lysozyme in females. Lysozyme and N-acetyl-D-glucosaminidase (NAG) were elevated in male and total proteins, b2-m, NAG and RBP in female exposed workers. Significant correlation between urinary concentrations of nickel on one side and that of b2-m in women (r=0.462, p=0.022) and men (r=0.4, p=0.018) and of NAG in men (r=0.405, p=0.019) on the other side were found in exposed subjects. The results indicate adverse effects of soluble nickel compounds on the kidney tubular function.

Outcome of incidence:

Applicant's summary and conclusion

The authors reported that adverse effects on the kidney tubular function of exposed workers were indicated, potentially resulting from high
occupational exposures to soluble nickel compounds.
