Additional information

The acute toxicity of Bronopol was examined in a static test system according to methods comparable to OECD guideline 202 with Daphnia magna as test organism [The Boots Company 1981]. The 48 h EC50 value was determined to be 1.4 mg/L (nominal).

A supporting study is available which was conducted according to ISO guideline 14669 with the saltwater species Acartia tonsa. At test termination after 48 h an EC50 of 3.5 mg/L (nominal) was determined [Knoll MicroCheck 1998].
