Scandinavian Journal of Work, Environment & Health
|January 1, 1976
Summary
Foundry fumes contain metals like lead, copper, and zinc. Airborne metal concentrations in foundries indicate potential health hazards for workers, varying by alloy and melting process.
Area of Science:
- Industrial Hygiene
- Environmental Science
- Occupational Health
Background:
- Metal fumes are generated during melting and casting processes in foundries.
- The composition of these fumes can be influenced by various factors, including alloy type, scrap quality, and melting techniques.
- Understanding fume composition is crucial for assessing potential workplace hazards.
Purpose of the Study:
- To analyze the metal content of melting and casting fumes.
- To evaluate the exposure levels of foundry workers to airborne metal fumes.
- To identify potential health risks associated with metal fume exposure in foundries.
Main Methods:
- Analysis of metal content in fumes using X-ray fluorescence, atomic absorption, and mass spectrometry.
- Measurement of airborne metal concentrations in steel, iron, and copper alloy foundries.
- Evaluation of foundry workers' exposure to metal fumes.
Main Results:
- Fume composition varied significantly based on alloy type, scrap quality, and melting process.
- Airborne concentrations of lead, copper, and zinc were measured in multiple foundry settings.
- Elevated levels of lead, copper, and zinc were detected, indicating potential exposure risks.
Conclusions:
- Foundry melting and casting processes generate metal fumes with variable compositions.
- Exposure to airborne lead, copper, and zinc in foundries poses a potential health hazard to workers.
- Further occupational health and safety measures are warranted to mitigate risks.
