Which of the following is NOT a characteristic of SO2 toxicology?

+
+
++

a. SO2 is a major reducing-type air pollutant.

+
++

b. Increased airflow rate increases the amount of SO2 inhaled.

+
++

c. SO2 inhalation causes vasoconstriction and increased blood pressure.

+
++

d. SO2 is predominately absorbed in the conducting airways.

+
++

e. SO2 inhalation increases mucus secretion in humans.

++
++
++

+
+
++

a. vasoconstriction.

+
++

b. decreased mucus secretion.

+
++

c. an anti-inflammatory response.

+
++

d. vasodilation.

+
++

e. bronchoconstriction.

++
++
++

All of the following statements regarding particulate matter are true EXCEPT:

+
+
++

a. Metals are most commonly released into the environment during coal and oil combustion.

+
++

b. The interaction of gases and particles in the atmosphere can create a more toxic product than the gas or particle alone.

+
++

c. Solubility does not play a role in the bioavailability of a metal.

+
++

d. The earth’s crust is an important source of atmospheric magnesium.

+
++

e. Diesel exhaust contains reducing- and oxidant-type air pollutants.
