CHAPTER 22
Environmental Chemistry
CHAPTER STUDY OBJECTIVES
1.Explain the relevant chemical reactions and phenomena occurring in the stratosphere and troposphere
SKILLS TO MASTER: Calculating atmospheric residence times, naming and drawing
CFCs, writing reactions explaining acid rain and photochemical smog, calculating an AQHI, explaining atmospheric warming.
KEY CONCEPTS: The structure of the atmosphere is based on how temperature
varies with altitude.
2.Explain the relevant chemical reactions occurring in the aquatic phase
SKILLS TO MASTER: Calculating alkalinity, interpreting a Pourbaix diagram,
calculating BOD and COD, using MAC and TDI values.
KEY CONCEPTS: Lakes with high carbonate concentration are somewhat protected
from acidification. The oxidative or reducing power of a body of water is quantified by the value of pE.
3.Describe some of the major pollutants of interest in the environment SKILLS TO MASTER: Recognizing hydrophilic versus hydrophobic pollutants, drawing and naming PCBs, dioxins and furans, calculating TEQ values.
KEY CONCEPTS: We need to be aware of the many emerging contaminants in the
environment Metal ions are often in the form of complexes in the environment. The relative toxicities of many compounds can be quantified using Toxic Equivalency Factors. Many pollutants of concern are lipophilic.
4.Describe how chemical species move through the environment SKILLS TO MASTER: Using Henry’s law to calculate the partitioning of a pollutant between water and air, using a distribution coefficient to do the same between water and sediments, using a bioconcentration factor to do the same between water and a living organism.
KEY CONCEPTS: Pollutants move through the environment and become distributed
in the atmosphere, hydrosphere and Biosphere Less polar (more lipophilic) compounds tend to bioccumulate and biomagnify.Copyright © 2021 John Wiley & Sons Canada, Ltd. Unauthorized copying, distribution, or transmission of this page is prohibited
