CASE STUDIES:

The Audiological Health of Horn Players
Wayne J. Wilson, Ian O'Brien and Andrew P. Bradley

1. There is strong evidence that horn players are at risk
    of noise induced hearing loss from their musical activities.
    True or False?

True
False
2. The overwhelming majority of musicians in this study who
    used hearing protection described playing while wearing
    earplugs as 'impossible'. True or False?
True
False
Analytical Method Validation for the Determination of 2,3,3,3-Tetrafluoropropene in Air Samples Using Gas Chromatography with Flame Ionization Detection
Michael P. Mawn, Kristine Kurtz, Deborah Stahl, Richard L. Chalfant, Mary E. Koban and Barbara J. Dawson

3. Air sample collection methods for volatile refrigerants may
    require multiple sorbent tubes connected in series rather than
    a single tube with multiple sorbent beds to distinguish between
    storage migration and sample breakthrough. True or False?

True
False
4. A sampling tube with a larger sorbent bed loading is less
    likely to minimize breakthrough and migration. True or False?
True
False
Excursion Guidance Criteria to Guide Control of Peak Emission and Exposure to Airborne Engineered Particles
Peter McGarry, Lidia Morawska, Luke D. Knibbs and Howard Morris

5. The authors incorporated the following in their measurement
    methodology: To ensure the comparison of all measurement
    values was meaningful, each instrument was set to the ______
    sampling interval where possible. In addition, because the ability
    to resolve the peak concentration is influenced by the sampling
    frequency, it was set to ______ period possible for that instrument.

a. different; shortest
b. same; shortest
c. similar; longest
d. similar; maximum
6. The LBPC is defined as the _______ of the local work area
    particle number or mass concentration that excludes any
    contribution of particles from the nanotechnology process.
    This value is specific to each work environment and represents
    the ________ particle exposure not associated with the
    nanotechnology process.
a. minimum; ambient
b. median; average
c. average; ambient
d. median; median
Potential Exposures Associated with Indoor Marijuana Growing Operations
John W. Martyny, Kate A. Serrano and Mike V. Van Dyke

7. During this study, a total of 30 Indoor Marijuana Grows were
    evaluated to determine potential health hazards. The exposure
    determined to be of greatest concern was which of the
    following?

a. Exposure to pesticides
b. Exposure to UV light
c. Exposure to fungal spores
d. Exposure to bacteria
e. Exposure to noise
8. The exposure of greatest concern was found to be of the greatest
    magnitude when:
a. the plants were being watered.
b. the plants were being removed by law
          enforcement officers.
c. the plants were young.
d. the plants were hydroponically grown.
e. the plants were grown outside.
Temporal Variation of Size-fractionated Particulate Matter and Carbon Monoxide in Selected Microenvironments of the Milan Urban Area
A. Spinazzč, A. Cattaneo, G. Garramone and D.M. Cavallo

9. Considering the variation of concentration as function of time,
    an appreciable and statistically significant difference between
    working and non-working days is observed for CO, UFPs, and
    PM. True or False?

True
False
10. The highest concentrations of FP´, FP, and CP is detected
      during time spent:
a. in metro trains.
b. along busy streets
c. in office environments.
Biomonitoring Study of Dry Cleaning Workers Using Cytogenetic Tests and the Comet Assay
Ruta Everatt, Gražina Slapšyte, Jurate Mierauskiene, Veronika Dedonyte and Liuda Bakiene

11. Assays such as CA, MN and DNA damage correspond to
      which of the following categories?

a. hepatotoxicity
b. genotoxicity
c. proximal tubule indicators
d. nephrotoxicity
12. This study generated a clear dose-response relationship but
      concluded a lack of statistical significance in terms of MN
      frequency. True or False?
True
False
Prevention Guidance for Isocyanate-induced Asthma Using Occupational Surveillance Data
Carolyn Reeb-Whitaker, Naomi J. Anderson and David K. Bonauto

13. Work-related asthma is generally thought to be under-
      recognized and underreported. True or False?

True
False
14. Dermal protection for workers handling isocyanates could
      dispense with which of the following elements?
a. hepatotoxicity
b. genotoxicity
c. proximal tubule indicators
d. nephrotoxicity
