Toxic Body Burden 2D: Compartment Flow & Concentration-Time Simulator

How does a pollutant actually accumulate inside a living body? This 2D simulator models a xenobiotic entering through inhalation, ingestion or dermal contact, distributing between a blood compartment and a fatty-tissue compartment, and leaving through metabolic clearance — the same two-compartment first-order kinetics environmental toxicologists use to describe how persistent lipophilic pollutants like PCBs, dioxins and PFAS build up in tissue over chronic, repeated exposure. A draggable flow diagram shows particles streaming from the chosen exposure route into the bloodstream and settling into the fat depot at a rate set by the toxicant's lipophilicity, while a live concentration-time chart plots blood and fat levels as the exposure runs, and readouts contrast a common naive half-life shortcut against the true, eigenvalue-corrected elimination half-life of the coupled system.
