Basic Course: Supplemental Topics
The CCC can then be set as equal to the FCV, unless an adjustment is made to factor in other available data for deriving the CCC. For instance, the final chronic value can be adjusted downward to reflect available data from plant studies that yield a Final Plant Value (FPV) or from studies on commercially or recreationally important animal species yielding a Final Residue Value (FRV).
