New international standards for aerosol sampling were tested on workplace instruments. While some samplers performed adequately, revisions are recommended to simplify tests and improve accuracy for inhalable aerosol monitoring.

Area of Science:

  • Occupational hygiene and industrial toxicology
  • Aerosol science and particle characterization
  • Environmental monitoring and regulatory compliance

Background:

  • International conventions for sampling inhalable, thoracic, and respirable aerosol fractions have been adopted.
  • A draft standard by the Comité Européen de Normalisation (CEN) outlines performance criteria for workplace aerosol sampling instruments.

Purpose of the Study:

  • To verify the experimental, statistical, and mathematical procedures in the draft CEN performance standard.
  • To assess the applicability of these procedures to inhalable aerosol samplers.
  • To provide recommendations for revising the CEN draft standard for practical implementation.

Main Methods:

  • Eight types of personal inhalable aerosol samplers, commonly used in European workplaces, were tested.

  • The study applied the procedures recommended in the draft CEN performance standard to these samplers.
  • Experimental data on sampler performance under various conditions were collected and analyzed.

    • Main Results:

    • Several tested samplers demonstrated adequate performance according to the inhalable sampling convention under limited workplace conditions.
    • Sampler performance was generally best under low external wind speeds, simulating indoor workplace environments.
    • The study identified significant experimental errors, impacting the precision of the performance data.

    Conclusions:

    • Recommendations were made to revise the CEN draft standard, focusing on simplifying tests and reducing costs.
    • Further development of simpler test facilities and methods is necessary.
    • The collected performance data, despite experimental limitations, offer valuable input for regulating and implementing the CEN inhalable sampling convention in occupational hygiene practice.
