Here are two articles I'd like you to read. You may need some information from them for your homework.
The article, Mercury Pathways to Fish by EPRI (Electrical Power Research Institute) has some neat color pictures and graphs. A copy of that file is in the Course Documents Folder.
The second article is about a pesticide. Go to the Blackboard site. The article is in the Course Documents folder and is called Pirate Fear. It is a brief article. You can find more about Pirate, here to see how the matter came out.
