8. For each of the biogeochemical cycles in the table below, list at least three areas on Earth
where the chemical elements or compounds are stored (i.e., reservoirs).
Biogeochemical cycles
Storage pools or reservoirs
Water
Carbon
Nitrogen
Phosphorus
9. For the three biogeochemical cycles listed below, choose two reservoirs you have listed in the table
from Question #8 and describe how the chemical elements/compounds moves between the two reservoirs.
Note, you do not have to describe the complete cycle for each element/compound, simply describe the
processes that connect two of the reservoirs that make up the cycle.
Water:
Carbon:
Nitrogen:
3. Mention the biogeochemical cycles in nature give an example of each
1. describe key aspects of the atmosphere related to human well-being, such as oxygen's role as a limiting factor, the greenhouse effect, and the tropospheric ozone layer.
2. identify types of stationary and mobile anthropogenic air pollutants
3. Describe the hydrologic cycle in specific terms, especially related to sources of fresh drinking water. Also, provide examples of point and nonpoint sources if pollution
4. characterize the physical-chemical properties of environmental contaminants related to their behavior in the environment
5. assess the advantage and disadvantages of toxicology compared with epidemiology as sources of information about the human health effects of environmental chemicals
6. describe the assumptions associated with estimating absorbed and biological effective doses.
7. explain why risk assessors use a reference dose to quantify noncarcinogenic toxicity but use a cancer slope factor to qualify carcinogenic toxicity
8. identify characteristics that influence…
