CASE STUDIES:

Fertilizer Use and Self Reported Respiratory and Dermal Symptoms Among Tree Planters
Melanie Gorman Ng, Ernst Stjernberg, Mieke Koehoorn, Paul A. Demers, Meghan Winters and Hugh W. Davies

1. How are seedlings fertilized in the British Columbia tree
    planting industry?

a. Tree planters apply nitrogen, phosphorus and
          potassium (NPK) fertilizer dissolved in water
          to the soil surrounding the seedlings after
          planting.
b. Tree planters bury polymer-coated NPK fertilizer
          sachets in the soil alongside seedlings at the
          time of planting.
c. Fertilizers are used at seedling nurseries and
          are not directly used by tree planters.
d. Tree planters apply a scoop of powdered NPK
          fertilizer to the soil surrounding the seedlings
          at the time of planting.
2. Tree planters who were not exposed to fertilizer were more
    likely than the highest exposure group (37 or more days of
    fertilizer exposure) to report that they usually brought up
    phlegm from the chest. True or False?
True
False
Ion Mobility Spectrometry as a Tool in Evaluating the Efficacy of Cleaning Protocol for Clandestine Methamphetamine Laboratory Remediation
Holly McCall, Jordan Moran, Brittany Yeager and Suzanne Bell

3. Methamphetamine is most volatile under basic conditions.
    True or False?

True
False
4. NIOSH recommends a surface sampling area of what
    dimensions?
a. 10 × 10 cm2
b. 10 × 10 in2

5. UV exposure of the eye is most intense at mid-day.
    True or False?

True
False

Exposure Limit Values for Nanomaterials – Capacity and Willingness of Users to Apply a Precautionary Approach
Pieter van Broekhuizen and Baerbel Dorbeck-Jung

9. Which of the following choices do the authors most strongly
    support in this article?

a. better specific health based OELs, because
          a health-based approach is always preferable
b. generic OELs, because generally there is
          multiple exposure to nanomaterials from
          different sources
c. no need to develop OELs, no amount of
          exposure is acceptable
10. Which of the following choices would best explain employers'
      beliefs regarding nano reference values?
a. it is the preferred way to manage potential
          workplace risks
b. it is the way to assure that care is taken to
          provide workers with a safe workplace
c. it is a means to comply with their duty of
