Description:
The use of reconstituted waters is deeply entrenched in many standardized aquatic toxicity testing protocols The primary appeal of reconstituted waters is inter-laboratory comparability, such that experiments performed in different laboratories can be conducted in (nominally) identical waters While several formulations of reconstituted waters have been developed over the years, many aquatic toxicity test protocols from the US EPA and ASTM use a formulation that has its roots in a publication by Marking and Dawson (1973). Using reconstituted waters that are more representative of natural waters should improve assessment of chemicals whose toxicity is influenced by the ionic composition of the water (eg, many cationic metals), and may also improve performance of some organisms found to be sensitive to the ionic composition of water (eg, Hyalella)
