Participants are required to dilute the sample provided in line with their usual practice, and to determine the EC50 (or IC50) dilution using any or all of the ecotoxicity tests listed. The solution will contain zinc sulfate at a concentration in the range 10 to 200mgZn/L. The % dilutions to produce an EC50 returned will be converted to mg Zn/L and performance scores awarded based on a suitable assigned value with a percentage SDPA of 30%.
