Materials and methods

Principles of method if other than guideline:
Volatile pollutants produced from several rubber goods manufacturing processes were sampled and analyzed. Samples were collected in the vulcanization areas of a shoe-sole factory, a tire retreading operation, and also in the extrusion areas of the retreading operation and an insulated cable manufacturer. Volatile organics from the vulcanization and extrusion areas were collected on activated charcoal, desorbed with trichlorofluoromethane and analyzed by GC/MS.

Applicant's summary and conclusion

Conclusions:
Volatile pollutants produced from several rubber goods manufacturing processes were collected on activated charcoal and after desorption analyzed by GC/MS. Cumene hydroxide was not detected in samples collected in the vulcanization areas of a shoe-sole factory and in the vulcanization and extrusion areas of a tire retreading factory (<1 µg/m³). Cumene hydroperoxide was detected in samples collected in the extrusion areas of an electrical cables insulation plant in concentrations ranging from 0 to 60 µg/m³. The authors presumed dicumyl peroxide as probable source.
