An air sampler is used to collect particles less than 10 /Lm in
diameter. The sampler is located downwind from a steel plant. The
accompanying data are for particulate samples collected on two
different days.
Sample 1
Sample 2
Element
Concentration (ppm)
Concentration (ppm)
Al
2130
1940
Fe
1024
1520
Mn
16.8
20.6
Cr
1.2
2.9
Ni
0.7
1.8
a. For both samples, calculate the noncrustal
abundance of Fe, Mn, Cr, and Ni . Use AI as the reference element.
Use the upper crust values from Table 8-14.
b. For particles emitted by the steel plant,
MnlFe = 0.009, CrlFe = 0.003, and NilFe = 0.002. Using the
noncrustal abundances of Fe, Mn, Cr, and Ni, do emissions from the
steel plant contribute to the aerosol chemistry? Explain.
c. If your answer to part (b) is yes, what
percent of aerosol sample I and aerosol sample 2 is due to
emissions from the steel plant?
