Workers in German soft tissue paper factories exposed to high dust and fiber levels showed reduced lung function, particularly forced vital capacity (FVC). This indicates a need for dust reduction and preventive measures to protect worker respiratory health.

Area of Science:

  • Occupational Health
  • Pulmonary Medicine
  • Environmental Health

Background:

  • Soft tissue paper production involves potential exposure to inhalable, respirable dust, and fibers.
  • Occupational dust exposure is a known risk factor for respiratory diseases.

Purpose of the Study:

  • To investigate the correlation between dust and fiber exposure and lung function parameters in German soft tissue paper factory workers.
  • To quantify the impact of cumulative exposure on spirometry results.

Main Methods:

  • Ambient air monitoring for dust and fibers in nine factories.
  • Spirometry (FVC, FEV(1)) performed on 1,047 workers across different exposure levels.
  • Multiple linear and logistic regression analyses accounting for confounders like age, sex, and smoking.

Main Results:

  • Mean concentrations of inhalable dust, respirable dust, and fibers were measured.
  • Significant decreases in forced vital capacity (FVC) were observed with increasing cumulative dust and fiber exposure.
  • Forced expiratory volume in one second (FEV(1)) also showed a decrease, with dose-response relationships more pronounced for FVC, suggesting a restrictive lung function pattern.

Conclusions:

  • High ambient dust concentrations in soft tissue paper factories are associated with adverse effects on lung function.
  • Reduction of dust exposure and implementation of secondary preventive measures are recommended to protect worker respiratory health.
