Calculadora de Mercúrio em Peixes

This calculator estimates weekly mercury intake from fish consumption based on the type of fish, amount consumed, and body weight. Mercury is a heavy metal that accumulates in the aquatic food chain, especially in predatory fish. The tool uses average mercury concentrations for each species (in ppm) and calculates the weekly dose in micrograms, comparing it with the safe limit established by the EPA (U.S. Environmental Protection Agency).

The operation is straightforward: the user selects the fish type (such as tuna, salmon, or tilapia), enters how many servings they eat per week and the weight of each serving in grams. The system multiplies these values by the typical mercury concentration of the chosen species. Then it calculates the individual safe limit based on body weight (1.6 µg of mercury per kg of body weight per week). The result shows whether the intake is within the recommended range or if there is a risk of excess.

Use this calculator when you want to monitor your mercury exposure, especially if you consume fish frequently, are pregnant, breastfeeding, or planning to become pregnant. Mercury can affect the developing nervous system. The tool is also useful for health and nutrition professionals advising patients on safe seafood consumption.

Important caveats: mercury values per species are averages and may vary by region, season, and fish size. The calculator does not replace medical advice. Pregnant women should follow specific recommendations from health agencies, such as avoiding high-mercury fish (shark, king mackerel, swordfish). Consult Anvisa or the EPA for updated guidelines.
