Society and Chemistry

Prepared by: Claire Watson

Goal of today's class:

To assess the effectiveness of some applications of chemical reactions that are used to address social and environmental needs and problems

Clean up Song

There are 4 remediation strategies

  • Do nothing and keep people off the land
  • Cover or encase contaminated area
  • Excavate (dig up) or replace the soil with clean soil.
  • Treat using chemical and biological processes (see p. 218-220) REMEDIATION

The specific chemistry topic REMEDIATION

Remediation (see p. 218) definition

The process of treating contaminated land or water so that it is safe for use again

Does this work in Malaysia and Canada?

First Task: in your groups (each side of room will be a group) Therefore Left and Right

Video on actual contamination

Let's look at the following cases: BRIDGE REality to Science

CBS Presentation on the Gulf of Mexico

(Relates to Nelson book p. 220)

Bioremediation (p. 220)

Watch this video:

Gulf of Mexico

Ted Talk on Boreal Forest of Canada (Oil Sands)

Malaysian Tanker Example

BP Oil Spill in Gulf of Mexico

Canadian Example "True cost of oil"

Ted Talk on Boreal Forest: True cost of oil

Consider: public, government and company perspective

Malaysian Oil Spill

Consider the: governmental, public and company perspective of this oil spill

iPad Presentation

Shale Drilling Pros and Cons: Relates to Video we watched yesterday.

Slag Heaps

See the coal slag heaps:

Waste Dumps

Solutions, what can we do?

Physical Remediation (p. 219) Group 1

Chemical Remediation (p. 219) Group 2

  • Stabilization and solidification
  • Chemical Oxidation
  • Electrolysis

Biological Remediation (p. 219-220) Group 1

Phytoremediation

In your groups we will discuss the following:

In your groups briefly explain, what each of the remediations are and discuss which remediation can be used to solve some of the problems outlined in the video.

Electrolysis

Chemical Reaction for Bioremediation

Oxidation Reaction
