Abstract: The study of any system, including biological systems, usually entails an analysis of inputs and outputs, and system behaviour can be assessed on basis of mathematical modelling and simulation. For an environmental xenobiotic source with an assumed harmonic behaviour, the xenobiotic concentration evolution within a biological system could be determined, assuming an analogy with a linear structure characterized by xenobiotic compounds of both dissipating and accumulating types. One could hope to show that a mathematical model described by a differential equation of order two with concentrated parameters could be accepted for a complex process of an environmental xenobiotic absorption by a linear structure. In line with this idea, one could define a hypothetical situation in which, from an environmental xenobiotic source with harmonic behaviour, the xenobiotic is absorbed by the biologic organism modelled as a system with a linear structure. The simulation diagram for the spatial vector of concentration, as resultant oscillation wave depicting the resonant absorption process of the environmental xenobiotic has been determined on basis of MATLAB software with SIMULINK and SimPowerSystems extensions. The results determine the variation in time of the spatial vector of concentration as periodical, with the wave shape determined by taking into consideration a modulation of the main excitation harmonic provided by the xenobiotic, and the resulting high frequency modulating signal on the basis of elements specific to a xenobiotic absorption circuit. Through consideration of a hypothetic simulation diagram for the spatial vector of xenobiotic concentration in a biological system, this study aims to demonstrate the need for joint efforts by researchers in electrical and environmental engineering, medicine and computing for enhancing knowledge of the impacts of environmental xenobiotics on humans and other life forms.
