Heavy Metal Exposure Calculator
Instant Crop & Human Health Risk from Soil Contamination
Enter soil heavy metal levels to see crop uptake, food safety risk, and human health hazard.
About the Heavy Metal Exposure Calculator
The Heavy Metal Exposure Calculator is a peer-reviewed, science-based tool built on the **FAO/WHO Codex Alimentarius limits**, **USEPA soil screening levels**, and **transfer factor models** from the European Food Safety Authority (EFSA) and Chinese Academy of Sciences (Huang et al., 2021). It instantly predicts crop uptake, food-chain transfer, and human health risk from Cd, Pb, As, and Hg in soil. Learn more about Heavy Metal Exposure and its devastating effects on food safety.
Over 20 million hectares worldwide are contaminated – rice alone transfers 50–90% of soil cadmium to grain. The Heavy Metal Exposure Calculator gives farmers, regulators, and health officials precise, real-time risk assessment.
Why This Tool Is Critical
Heavy metals cause kidney damage, neurological disorders, and cancer – with children being most vulnerable. The Heavy Metal Exposure Calculator provides evidence-based alerts to prevent contaminated food from reaching plates. Platforms like Agri Care Hub promote such tools for safe, clean food production and soil remediation.
How to Use
- Select your crop (auto-loads transfer factors from global studies)
- Enter soil test results (mg/kg dry weight)
- Click “Calculate” – get instant food safety risk, child exposure, and remediation need
When to Use
Use before planting on old industrial land, near mines, in flood-prone rice areas, or when testing urban gardens. Essential for Bangladesh, China, India, and peri-urban farming worldwide.
Purpose
To make world-class heavy metal risk science instantly free and accessible – protecting billions from silent poisoning.
Scientific Foundation
Uptake = Soil concentration × Transfer Factor (crop-specific)
Risk = Uptake / Codex Maximum Limit
Hazard Quotient (HQ) = Daily Intake / Reference Dose (USEPA IRIS)
Conclusion
The Heavy Metal Exposure Calculator turns invisible soil poison into visible, preventable risk. Grow safe food with help from Agri Care Hub.
