ECOLOGY & ENVIRONMENT CALCULATOR
Fish Mercury Calculator
Calculate the mercury content in fish to assess environmental and health risks.
What is the Fish Mercury Calculator & How does it work?
Mercury is a toxic heavy metal that can accumulate in aquatic ecosystems, particularly in predatory fish. The concentration of mercury in fish increases as it moves up the food chain. This calculator helps estimate the potential mercury exposure from consuming fish.
The primary form of methylmercury, which is more toxic than inorganic mercury, accumulates in the muscle tissues of fish. The amount of methylmercury a person consumes depends on the type and quantity of fish eaten.

Frequently Asked Questions
How does the calculator estimate mercury exposure?
The calculator estimates mercury exposure by considering the type and quantity of fish consumed, as well as their methylmercury content.
What is methylmercury?
Methylmercury is a toxic form of mercury that accumulates in the muscle tissues of fish and can be harmful to humans if consumed in significant amounts.
Which fish have the highest levels of mercury?
Large, predatory fish such as shark, swordfish, king mackerel, and tilefish typically have the highest levels of mercury.
How often should I use this calculator?
You can use this calculator whenever you plan to consume fish or want to assess your ongoing mercury exposure from fish consumption.
Is there a safe level of mercury for humans?
The U.S. Environmental Protection Agency (EPA) recommends that pregnant women, nursing mothers, and young children limit their weekly intake of methylmercury to 0.1 micrograms per kilogram of body weight.
Can I input different types of fish?
Yes, the calculator allows you to input various types of fish to estimate your mercury exposure based on your specific diet.
What should I do if my mercury exposure is high?
If your mercury exposure is high, consider reducing your consumption of predatory fish and consulting a healthcare professional for advice.
