EES 202 Biogeochemistry
Problem Set 2 (25 points)
Spring 2017

SHEET WITH YOUR WORK.
1. Natural sources add sulfur dioxide (SO2) to the atmosphere at a rate of about 108 metric tons of S per year.
The background concentration of atmospheric SO2, measured in remote areas where anthropogenic
sources are not likely to have much influence, is about 0.2 parts per billion, by volume [ppb(v)]. What is
the residence time, in days, of atmospheric SO2 in remote regions? Useful info: molar mass of air = 28.96
g/mol, mass of Earth’s atmosphere is 5.14 x 1021 g, and ppb(v) is equivalent to mole fraction. 2. A stable and highly soluble pollutant is dumped into a lake at the rate of 0.16 metric tons per day. The
lake volume is 4 x 107 m3 and the average water flow-through rate is 8 x 104 m3/day. Ignore evaporation
from the lake surface and assume the pollutant is uniformly mixed in the lake. What eventual steady-state
concentration (in ppm) will the pollutant reach? 3. Examine the Piper Diagram on the following page characterizing the chemistry of a locally wellknown waterway.
(a) Based on where the majority of points plot on the diagram, classify the type of water chemistry
represented by these samples (see the write-up for Piper Diagrams in Lab 7). (b) For the INDICATED DATA POINT (WITH ARROW), what are the percentages of each ion? Cation
Ca2+
Mg2+
Na+ + K+ Percentage Anion
Percentage
2SO4
ClCO32- + HCO3- (c) On the diagram, PLOT a point on each part representing a water sample having the following
percent ions: Ca2+ = 70, Mg2+ = 20, (Na+ + K+) = 10,
SO42- = 60, Cl- = 5, and (CO32- + HCO3-) = 35
