Analysis and Simulation of Organism Survival: A Toxicokinetic-Toxicodynamic Model for Substance Exposure

Abstract

This study develops a mathematical model to analyze the effects of chemical exposure on organism population dynamics. Using a set of TK-TD differential equations, the model examines the interactions between chemical concentration, damage, and population survival. Numerical simulations validate the theoretical results and explore the system’s behavior under different scenarios. The findings provide insights into the long-term impacts of chemical stress on population resilience and demonstrate the utility of mathematical models for environmental risk assessment.
