IAQ in Developing Countries – Elevated Outdoor and Indoor PM2.5 Levels

Presenter: Donald Weekes, CIH, CSP, FAIHA, Partner, InAIR Environmental, Ltd., Ottawa, ON, Canada.

Elevated airborne particulate levels, both outdoors and indoors, in developing countries have results in severe, adverse health effects, particularly for women and children. In a recent "Atmospheric Environment" paper published in March, 2016 entitled, “Indoor air quality scenario in India—An outline of household fuel combustion” by Rohra & Taneja of the Department of Chemistry, Dr. B.R. Ambedkar University, Agra, India, the following issues were outlined:

  1. Burning of Fossil Fuels for Cooking. 
  2. 80 percent of rural households use biomass fuel for cooking.One quarter of all ambient PM2.5 in developing nations is from co​​oking.
  3. 80 percent of women are exposed to the health perils associated with elevated particulate levels.
  4. 27.5 percent of under-five mortality in India is a result of the deadly effects.
  5. Worldwide: four million deaths and 5 percent disability-adjusted life-years result from exposure to cooking particulates and fumes.

This presentation will discuss the industrial hygienist's role in this issue and will denote what can be done to reduce the airborne particulate levels both outdoors and indoors.


11:00 a.m. - 11:30 a.m.

Additive Manufacturing & 3D Printing: Lessons from the Field

Presenter: Eric Glassford, CIH, Industrial Hygienist, NIOSH, Cincinnati, OH.

Additive manufacturing builds objects by adding layers of material from the bottom up. This includes three-dimensional (3D) printing, a process increasingly used in the automotive and aerospace industries. The 3D printing process itself is rapidly evolving as new printing techniques, such as fused deposition modeling (FDM), are developed and printing materials containing engineered nanomaterials, such as carbon nanotubes, are evaluated. As a consequence, in some workplaces employee exposures and engineering controls have not yet been fully evaluated. In an effort to better understand this emerging technology, the National Institute for Occupational Safety and Health (NIOSH) has visited industries using additive manufacturing to evaluate employee exposures to contaminants released during additive manufacturing processes and the effectiveness of engineering controls. A NIOSH field team investigator will review past and current projects involving additive manufacturing. The presentation will discuss the air sampling techniques and direct-reading instrumentation that NIOSH field investigators use to assess workplace exposures.​​​​​​​​​​​​
