Section A: What is biomagnifications?
Biomagnification is a system of processes involved in the ecosystem wherein there is a presence of an increase of concentration in a substance that is involved in the food chain. Biomagnification may be a consequence of the following circumstances: a low or nonexistent rate of internal degradation of the substance (especially when the substance involved is water insoluble) and persistence (which refers to a substance that cannot be simply broken down by environmental processes).
Section B: Describe what is meant by the U.S. National Priorities List.
The U.S. National Priorities List refers to a list of sites that contains the national priorities on the releases, or threatened releases, of pollutants, contaminants, and hazardous substances throughout the United States of America and its territories. In addition, the U.S. National Priorities List also serves as a guide to the Environmental Protection Agency in determining sites that also need additional investigation.
Section C: What is meant by the term environmental policy? Give two examples of environmental policies that have been developed in the United States.
Environmental policy is a policy which establishes a framework for the protection of the environment. Usually, such policies take into account efforts that will prevent or eliminate any activity that poses damage to the environment, and threatens the overall harmony between man and the biosphere. Two examples of environmental policies developed in the United States include: a. the Atomic Energy Act (which seeks to protect the environment from radiation hazards and atomic waste) and b. the Clean Air Act (which seeks to provide standards for the quality of air in the country).
