Area of Science:

  • Industrial Hygiene
  • Analytical Chemistry
  • Occupational Health

Context:

  • Shoe manufacturing involves significant solvent use in glues and diluents.
  • Previous studies on solvent exposure in this industry are approximately 10 years old.
  • Understanding current solvent mixtures is crucial for worker safety.

Purpose:

  • To analyze the composition of glues and diluents used in footwear manufacturing.
  • To identify frequently occurring solvents and their concentrations.
  • To compare current solvent profiles with historical data and inform monitoring strategies.

Summary:

  • Gas chromatography-mass spectrometry identified solvents in 43 glues and 22 diluents. Acetone, ethylacetate, and cyclohexane were prevalent, with cyclohexane comprising ~40% of mixtures. Methyl ethyl ketone, 3-methylpentane, and 2-methylpentane were common, often without n-hexane. N-hexane was present in 32% of glues, usually at low concentrations (<10%).
  • The study indicates a shift in solvent exposure profiles in shoe factories compared to a decade ago.
  • Acetone, ethylacetate, methyl ethyl ketone, and cyclohexane are recommended for biological monitoring.

Impact:

  • Provides updated data on solvent composition in shoe factory adhesives.
  • Highlights the need for revised occupational exposure assessments and monitoring protocols.
  • Informs targeted biological monitoring strategies for enhanced worker protection.
