In general, the properties of a Species element must, by definition, be constant throughout your model (e.g., you would not want the Molecular Weight of a species The chemical (or non-chemical, such as bacterial or viral) constituents that are stored and transported through an environmental system in a contaminant transport model. In GoldSim, the Species element defines all of the contaminant species being simulated (and their properties). to take on different values in different locations in your model!). There are situations, however, in which you may wish to vary the Decay Rate or the stoichiometry for a species spatially in your model (i.e., have it take on different values at different locations in your model). For example, you may want a species to decay only in certain pathways (e.g., a pathway representing anoxic sediments; or a pathway representing the liver in a pharmacokinetic model).
GoldSim provides a mechanism for representing such behavior.
