Structures,
Properties, and Occurrence of Organic Compounds in Natural
Waters - II
|
| Overview |
| In
the second week of lectures devoted to organic geochemistry we continue
our study of the classification and nomenclature of organic compounds, and
we focus in particular on two classes of compounds most often involved in
contaminated waters: aromatic hydrocarbons and halogenated hydrocarbons. |
| Objectives |
 | Continue learning how to classify and
name organic compounds of relevance to aqueous
geochemistry (aromatic hydrocarbons, halogenated
hydrocarbons, alcohols, ethers, aldehydes, ketones,
etc.). |
| Learn about the behavior of organic
contaminant plumes (petroleum, halogenated
hydrocarbons). |
|
| Learning
Resources |
| Read: Chapter 6 (p.
182-220) in Kehew (2001)
Additional Questions to consider:
Here are some study guide questions to
contemplate as you read pages 182-220. You need not turn these
in, but after reading the text, you should be able to answer
these.
| Describe the geochemical conditions
in each of the zones in the Bemidji plume. How do
classes of hydrocarbon compounds vary among these
zones? |
| What are PCB's? Do they constitute a
significant threat to ground water quality? Why or why
not? |
| Which of the halogenated hydrocarbons
are most commonly detected in ground water? What are
the most important sources of these compounds, and
what properties control their mobility? |
| Describe the similarities of the
structures of alcohols and ethers. Which
representatives of these groups are important ground
water contaminants and why? |
| Which groups of organic compounds
contain the carbonyl group? What type of waste
contains these compounds? |
| What are dioxins and why are they of
concern? |
| What do the acronyms PAH and BTEX
stand for? |
| What is a heterocyclic compound? |
