CASE STUDIES:

Evaluation of Sampling Methods for Measuring Exposure to Volatile Inorganic Acids in Workplace Air. Part 2: Sampling Capacity and Breakthrough Tests for Sodium Carbonate-impregnated Filters
Martine Demange, Véronique Oury and Davy Rousset

1. Carbonate-impregnated quartz fiber filter can collect
    hydrofluoric acid. True or False?

True
False
2. In the presence of sodium chloride and nitric acid in
    workplace air, chlorides on impregnated filters imply
    occurrence of hydrochloric acid in workplace air. True
    or False?
True
False
Variability and Specificity Associated with Environmental Methamphetamine Sampling and Analysis
Mike V. Van Dyke, Kate A. Serrano, Shalece Kofford, John Contreras and John W. Martyny

3. This study looked at the variability in the results provided by
    three labs that analyzed spiked wipes for methamphetamine
    using NIOSH Method 9111. The study concluded that, at the
    concentrations tested:

a. Variability was low
b. Variability was high
c. Lab results were not comparable
d. Lab results were comparable
e. Both a and d
4. This study collected spiked samples that were contaminated
    with dust and latex paint in order to determine if dust and paint
    would alter the results of the testing. The researchers found that:
a. Paint does alter the results but dust does not
b. Both paint and dust alter the results
c. Neither paint nor dust alter the results
d. Only dust altered the results
The Influence of Activewear Worn Under Standard Work Coveralls on Whole-body Heat Loss
Jill Stapleton, Stephen Hardcastle and Glen P. Kenny

5. What are the components of whole-body heat loss?

a. change in core and skin temperatures
b. dry heat loss
c. evaporative heat loss
d. b) and c)
e. None of the above
6. Activewear garments promote heat loss by enabling the
    moisture produced on the skin's surface due to sweating to
    quickly be drawn to the outside of the clothing. True or False?
True
False
Performance Evaluation of Twenty-Six Combinations of Chemical Protective Clothing Materials and Chemicals after Repeated Exposures and Decontaminations
Pengfei Gao, Beth Tomasovic and Lauren Stein

7. By comparing the beginning and the ending cycles, after
    repeated exposure/decontamination:

a. the detergent method resulted in a longer
          mean BT value with a smaller mean SSPR.
b. the thermal method resulted in both longer
          mean BT and SSPR values.
c. the thermal method resulted in a longer mean
          BT value with a slightly smaller mean SSPR.
d. the detergent method resulted in a shorter
          mean BT value with a smaller mean SSPR.
8. In the thermal stability test, most of the clothing materials
    with weight gains were discolored. True or False?
True
False
Comparing Gravimetric and Real-Time Sampling of PM2.5 Concentrations Inside Truck Cabins
Ying Zhu, Thomas J. Smith, Mary E. Davis, Jonathan I. Levy, Robert Herrick and Hongyu Jiang

9. According to the article, which of the following is NOT a reason
    why PM2.5 is often linked to cardiovascular and pulmonary
    diseases?

a. ability to penetrate to the deepest portions of
          the lungs
b. large surface area
c. favored adsorption of toxic substances
d. asthmagen properties
10. A reasonable approach would be to use gravimetric analysis
      of filter samples collected concurrently with DustTrak
      measurements to calibrate the average mass concentration
      responses for the DustTrak. True or False?
True
False
A Strategy for Assessing Workplace Exposures to Nanomaterials
Gurumurthy Ramachandran, Michele Ostraat, Douglas E. Evans, Mark M. Methner, Patrick O'Shaughnessy, James D'Arcy, Charles L. Geraci, Edward Stevenson, Andrew Maynard and Keith Rickabaugh

11. Which of the following would not be a primary characteristic
      for evaluation of nanomaterial hazard?

a. number concentrations
b. surface area concentrations
c. mass concentrations
d. health-relevant time interval
e. plethysmography
12. The same OEL typically used for bulk counterparts can
      invariably be used for nanomaterials. True or False?
True
False
