Free environmental pollution calculator software: risk assessment, pollution indices, bioaccumulation & biometric calculators
What the ecotoxicology suite calculates
Human-health risk assessment: Estimated Daily Intake (EDI), Target Hazard Quotient (THQ), Hazard Index (HI / TTHQ) and carcinogenic risk (CR) for trace elements in food, water and soil — with built-in RfD and CSF reference values for 23 elements, batch mode for many samples, a THQ heatmap and Monte Carlo probabilistic analysis.
Pollution indices: Contamination Factor (CF), Pollution Load Index (PLI), Geoaccumulation Index (Igeo), Metal Pollution Index (MPI) and Håkanson ecological risk (Er, RI), each classified into published contamination tiers.
Bioaccumulation: Biota-Sediment Accumulation Factor (BSAF) and Bioaccumulation Factor (BAF) with LOD/2 imputation for below-detection values.
Biometric indices: Fulton's condition factor (K), Hepatosomatic Index (HSI) and Gonadosomatic Index (GSI) with group statistics and charts.
Modules accept pasted spreadsheets; risk and pollution also accept file uploads. Censored values are handled transparently, export CSV, high-resolution charts and a structured PDF report, and run entirely in your browser — no data is uploaded. Formulas and references are documented on the .
