The Law of Diminishing Returns in Determining the Environmental Cost of Mining in the Eastern Mediterranean Sea

Environmental standards, as independent/explanatory variables of C₂₁ capital costing functions, may refer to parts of space that we want to control in order to protect subsystems that are particularly sensitive and/or importance. In these cases, we need a quantitative relationship that links the environmental characteristics of the source of pollution to those of the reference/control points. In this article we will identify the capital cost functions C₂₁ = f (S_f), where S_f is a spatially distributed parameter (e.g. BOD), characteristic of an environmental model.
