Florida Everglades & mercury contamination

1. Mercury contamination was detected in Florida Everglades sediments by the State Environmental Department during the environmental quality assessment. The Department was puzzled about this finding because, the currently known industries in the area do not use mercury in their operations and there is no illegal dumping of medical waste containing mercury. So HOW DID MERCURY GET THERE?
Knowing the physical and chemical nature of mercury, answer the below questions to describe your theories on the source and origin of mercury in the Everglades sediments
a) Do you think, it was transported across the state or interstates and deposited;
b) If so, what are its sources,
c) How did it get transported and deposited?
d) What governed the transportation?
e) If it is not transported, do you think mercury occurrence could be indigenous to the Everglades, if so what is the source?

2. Describing the possibilities or ramifications of the following prompt: How would our pattern of life be different in the absence of the Clean Air Act and its amendments? Give examples.

3. Explain the difference between criteria pollutants and hazardous air pollutants and how they are regulated.

Dear Student,

Hi and thank you for using BrainMass. The solution below should get you started. In this particular task, you are being asked to offer an explanation about a phenomenon. I suggest using the questions as the basis for the outline, which should lead to around 500 words. Since this is supposition based on evidence and previously observed phenomenon, as long as you cite your position, you should be okay. Just let me know via the feedback section if you need further clarification. All the best with your studies.

Mercury Contamination: Florida Everglades Case

The Issue

Mercury contamination was detected in Florida Everglades sediments by the State Environmental Department during the environmental quality assessment. The Department was puzzled about this finding because, the currently known industries in the area do not use mercury in their operations and there is no illegal dumping of medical waste containing mercury. How did the mercury get there? Here, based on similar observed phenomenon elsewhere and in nearby locations, we discuss likely causes.

Theories and Suppositions

A theory related is that the chemical could have been transported to the everglades across the state and might even have had origins beyond Florida. According to the US Geological Survey (2013), "High levels of mercury have been measured in fish and wildlife in south Florida, particularly in the Everglades. Roughly 1 million acres of the Everglades are under a health advisory that recommends that anglers and others completely avoid consuming large mouth bass and several other species of fish ...Mercury body burdens of largemouth bass collected in the Everglades were ...
