Derivation of Chemical Limit Values for Water Quality: An International Perspective

This work included comparisons of the procedures and methods used to assess ecotoxicological data and derive different types of water quality limit values, and also assessed the potential for limit values derived in one jurisdiction to be adopted or adapted for use elsewhere.
What is very clear is that there are considerable differences between countries and regions with respect to the specific procedures used in their derivation. -
