• Used as a tool to understand and predict mercury cycling in lakes and mercury accumulation in fish.
• Used as a mass balance model for methylmercuty, Hg(II), and elemental mercury.
• Simulates cycling in individual lakes or in groups of lakes.
• Can be used to examine variations in mercury in fish among lakes and among regions.
• Incorporates geochemical cycling processes in lakes, including sources of mercury.
• Uses bioenergenics for a five-compartment food chain.
