N-nitrosamines in the rubber and tire industry

|September 21, 1979
Summary
Airborne N-nitrosomorpholine was detected in two rubber factories, potentially linking to increased cancer risks in workers. N-Nitrosodimethylamine was also found at lower concentrations in the same facilities.
Area of Science:
- Occupational health
- Environmental chemistry
- Industrial hygiene
Background:
- Rubber industry workers face elevated risks for certain cancers.
- Exposure to airborne contaminants in industrial settings is a significant concern.
Purpose of the Study:
- To quantify airborne N-nitrosomorpholine and N-nitrosodimethylamine levels in rubber manufacturing facilities.
- To investigate potential links between detected nitrosamine levels and cancer risks in rubber industry workers.
Main Methods:
- Air sampling was conducted in four rubber industry factories.
- Levels of airborne N-nitrosomorpholine and N-nitrosodimethylamine were measured using appropriate analytical techniques.
Main Results:
- N-nitrosomorpholine was detected in 2 of 4 factories, with concentrations ranging from 0 to 27 micrograms per cubic meter.
- N-Nitrosodimethylamine was also found in 2 factories, but at lower levels than N-nitrosomorpholine.
Conclusions:
- The presence of airborne N-nitrosomorpholine in rubber factories may contribute to the increased cancer risk observed in some rubber workers.
- Further research is warranted to establish a definitive causal link and explore mitigation strategies.
