Additional information

Two studies are available for algal toxicity. Both use biomass as the measured endpoint, which is not the preferred effect measurement. However, at least one was conducted to a recognised guideline. Only nominal concentrations are given, but this is not considered problematic for this low volatility, highly water soluble material. Both studies were in effect limit studies and neither established a true EC50 level. The highest dose tested without reaching the EC50 is selected as the key parameter.
