2. Environmental Biotech Major part is in detecting and monitoring pollution to determine how much is present

3. Biotech Examples Indicator species 1.Lichens: –Widely used as environmental indicators or bio-indicators –If air is highly contaminated with sulfur dioxide, only green algae will be present

4. Biotech Examples 2. Bioremediation –Using bacteria to cleanup oil and fuel spills

5. Bioremediation Examples Oleophilic bacteria Used to clean up oil spills Used to clean up the 1989 Exxon Valdez oil spill

6. Bioremediation Examples 80,000 gallon fuel leak in Hannah, SC (suburb of Charleston) Fuel from a military supply leaked into ground water Bacteria was used to remediate this problem

7. Biostimulation Adding nutrients to feed the bacteria This was used to feed the bacteria cleaning the Exxon Valdez clean up effort

8. Biodiesel Made from oil seeds such as soybeans and canola oil Decreases vehicle emissions

9. Phytoremediation Using hybrid Poplar trees to remove VOC’s (Volatile Organic Compounds) from soil Used effectively in Oregon at an illegal dumping site Used effectively at Aberdeen Proving Grounds, Md. –Disposable site of chemical warfare agents, munitions, and industrial chemicals

10. Limitations of using bio and phytoremediation Time –Much slower than chemical techniques Applicability –Does not apply to all sites Fear –People unsure if these methods have truly removed the contaminants
