The dilution water used in the toxicity tests may be natural seawater, hypersaline brine (100 ) prepared from natural seawater, or artificial seawater prepared from commercial sea salts, such as FORTY FATHOMSa or HW MARINEMIXa, if recommended in the method.
The dilution water in the toxicity tests has to be freshwater from the lake.
