Great lakes Flashcards

Terms Definitions
non-point-source pollution
term for pollution runoff (precipitation, car washing, watering and fertilizing crops or lawns, applying toxic herbicides or pesticides)
Demotechnic Growth
 
•Exponential human growth and utilization of freshwater.
•BUT:  consumption increases in response to rising supply.
•Environmental Problems: 
population growth + technological growth
 
point-source pollution
Pollutants discharged from a single identifiable location (e.g., pipes, ditches, channels, sewers, tunnels, containers of various types).
Invasive species
plants and animals that have been moved to or migrated to places where they are not native, threatening local food chain
Ecosystem
a system formed by the interaction of a community of organisms with their physical environment
What are the Standards?


•standard is defined as 0‰. 

•For Carbon, the international standard is Pee Dee Belemnite, a carbonate formation.
•The Pee Dee Belemnite absolute ratio of 13C/12C is 0.0112372.  
•Materials with ratios of 13C/12C > 0.00112372 have positive delta values
•Those with ratios of 13C/12C < 0.00112372 have negative delta values.

•For Nitrogen, the international standard is the Nitrogen content of air.
•The Nitrogen in Air absolute ratio of 15N/14N is 0.003676.
•Materials with ratios > 0.003676 have positive values.
Future of great lakes


•Some progress, some signs of recovery, but pollution will continue to be a major concern in the years to come.



•A broader scope of regulation of toxic chemicals may be necessary as research and monitoring reveal practices that are harmful.



•More stringent controls of waste disposal are already being applied in many locations.




•Agricultural practices are being examined because of the far-reaching effects of pesticides and fertilizers. 
What are stable isotopes
 
•Isotopes are atoms of the same element that differ in atomic mass, due to differences in the number of neutrons contained in the atoms' nuclei.
•Example:
– 12C (6 neutrons, stable)
– 13C (7 neutrons, stable)
–  14C (8 neutrons, unstable)

•Stable isotopes are measured by gas isotope-ratio mass spectroscopy.

•The sample is converted into a gas (CO2, N2)

•The gas molecules are ionized in the Ion Source 


 
chemical pollution in great lakes


Many of the chemical pollutants discharged in the Great Lakes can mimic hormonal activity:
•  Development
•  Sexual differentiation

  Metabolism

Chemicals with hormonal activity include, among others:
 
•Halogenated aromatic      compounds such as PCBs  and PBDEs
•Synthetic estrogens
•Natural estrogens
 
 Sources:

•  Runoff into streams (urban, industrial, agricultural)
•  Storm sewers 
•  Waste water treatment plants’ discharge
