Metal Intake Calculator Instructions

Purpose: This calculator determines the maximum safe daily intake (in grams) of a product based on the concentrations of specific metals present in it. It utilizes guidelines established by the AHPA, FDA, and EPA to ensure that the user’s daily metal consumption does not exceed recommended limits.

• Metal Concentration Input: For each metal listed, input the concentration (in parts per billion or ppb) as indicated by your lab report.
• Calculation: Once you’ve entered the concentrations for all metals, click the “Calculate” button. The calculator will use the provided formula to compute the maximum safe limit based on daily intake for each metal.
• Interpretation: The results will be displayed below each metal. This value represents the maximum quantity (in grams) of the product that can be safely consumed daily, considering the metal concentrations you’ve inputted.
• Note: Ensure the values entered are accurate and in the correct unit (ppb). Any non-numeric or negative input will result in an error message.
