Hoeting, J.A., and Anthony R. Olsen. 1998. Are the fish safe to eat? Assessing mercury levels in fish in Maine lakes. In: Case Studies: a Collaboration Between Academe and Industry, Chapter 1, Society for Industrial and Applied Mathematics and the American Statistical Association.
Mercury is a toxic metal sometimes found in fish consumed by humans. The state of Maine conducted a field study of 115 lakes to characterize mercury levels in fish, measuring mercury and 10 variables on lake characteristics. From these data, we can investigate four questions of interest: 1. Are mercury levels high enough to be of concern in Maine lakes? 2. Do dams and other man-made flowage controls increase mercury levels? 3. Do different types of lakes have different mercury levels? 4. Which lake characteristics best predict mercury levels?
