Occupational nickel dermatitis in the electroforming industry
Contact Dermatitis
|October 1, 1980
Summary
Occupational dermatitis linked to nickel exposure in an electroforming plant was investigated. Improved hygiene reduced cases, but nickel allergy persisted in some workers.
Area of Science:
- Occupational Health
- Dermatology
- Toxicology
Background:
- Occupational dermatitis is a common skin condition.
- Nickel is a frequent cause of allergic contact dermatitis.
- Electroforming processes can involve significant nickel exposure.
Purpose of the Study:
- To investigate an outbreak of occupational dermatitis in an electroforming plant.
- To identify the causative agent and assess nickel allergy prevalence.
- To evaluate the effectiveness of industrial hygiene interventions.
Main Methods:
- Case study of an occupational dermatitis outbreak.
- Patch testing with nickel chloride and nickel sulphate.
- Assessment of dermatitis incidence before and after hygiene improvements.
Main Results:
- Nickel allergy was confirmed in 13 of 27 exposed workers.
- Nickel chloride proved a more reliable patch test allergen than nickel sulphate.
- Enhanced industrial hygiene led to a rapid decrease in dermatitis incidence.
Conclusions:
- Nickel exposure in electroforming plants can cause significant occupational dermatitis.
- Nickel allergy is a key factor in this outbreak.
- Persistent nickel sensitivity can occur even after exposure cessation.

01:03Precipitation Gravimetry
Precipitation gravimetry is based on converting an analyte into a sparingly soluble precipitate, which is separated by filtration and weighed. An ideal precipitate should be pure, insoluble, of known composition, and easily filtered from the reaction mixture.
In determining nickel by gravimetric analysis, a precipitant of ethanolic dimethylglyoxime is added to a hot nickel salt solution. This is quickly followed by the dropwise addition of dilute ammonia solution until precipitation occurs. A...

01:08Electrodeposition
Electrodeposition is a technique used to separate an analyte from interferents by electrochemical processes. Here, the analyte is a metal ion that can be deposited on an electrode immersed in the sample solution. The electrochemical setup consists of an anode and a cathode. When an electric current is applied to the setup, oxidation occurs at the anode. At the cathode, which consists of a large metal surface, metal ions undergo reduction and deposit onto the surface.
