PPR Specialization Overview

9-27-12

Prof. Trish Holden, Bren School

+Why PPR ?

Pollution Waste management: driven by population and

development Emerging pollutants in U.S. , EU, etc. Legacy pollutants globally (Hg, DDT, etc.) Soil (agricultural sustainability), water: scarce resources

Prevention “Greening” of industry / products Analysis of life cycle (raw materials to end-of-life for

products) Resource conservation By-product recovery

Remediation Ex- vs. in-situ Engineered vs. monitored natural attenuation

(frog: http://www.greenchemistrynetwork.org/gcp.htm)

+Example problem

2005 Benzene spill in Songhua River, PRC

Songhua River: drinking water source Harbin (9 M people) Other PRC cities Russia: x-border city of 0.7 M

people

Benzene toxic carcinogen somewhat soluble in water volatile can biodegrade

+Example: questions & concerns How hazardous is this spill for humans and biota?

How far downstream will the pollution travel?

What are the pollutant fates?

What can we do about the pollution, and when?

How can we avoid this in the future?

+YOUR POS

individual POS initial meeting w/ advisor to discuss background, and goals follow-up, as desired

suggested classes (website ; example POS) You may be well-versed already in some...

“Combo” may make sense w/ other specialization, for you PPR and CEM PPR and WRM..
