• Description:
  Many occupational related diseases due inhalation hazards are associated with where a contaminant may deposit in the lung. The American Conference of Governmental Industrial Hygienists (ACGIH) has defined the size of particles that may enter the nose or mouth with the Inhalable Sampling Criterion. The Institute of Occupational Medicine (IOM) sampler was developed to sample the inhalable fraction of particles. Pesticides are semi-volatile organic compounds (SVOC) that may exist both as a droplet (particle) and as a vapor. ACGIH has given compounds contributing a significant amount of exposure to both the vapor and particle phase of an SVOC with the Inhalable Fraction and Vapor (IFV) designation. Many occupational chemicals, such as pesticides, are given the IFV designation. The OSHA Versatile Sampler (OVS) is commonly used to sample pesticides and other chemicals with the IFV designation capturing both particles and vapors but was not designed as a size-selective sampler. The IFV Pro Sampler (SKC Ltd.) is designed to be size-selective, following the ACGIH inhalable sampling criterion, and have a sorbent tube to capture both particles and vapor simultaneously. This study evaluated the size-selective capabilities of the SKC IFV Pro sampler to determine whether it adheres to the ACGIH inhalable sampling criterion through comparison to the IOM sampler, as well as its efficiency as a particle and vapor sampler by comparing it to the OVS sampler. The study results indicate that the efficiency of the SKC IFV Pro is not significantly different from the IOM sampler (p = 0.517) and that the sampled mass of the SKC IFV Pro was significantly different from the OVS sampler (p = 0.007), collecting 41% more mass per sample, indicating the OVS sampler may be under sampling at the inhalable size fraction.
