Additional information

The lowest valid acute test results for fish, daphnids and algae were as follows:

Oncorhynchus mykiss: 96-h LC50= 7.07 mg/L;

Daphnia magna: 48-h EC50= 1.007 mg/L;

Desmodesmus subspicatus: 72-h EbC50= 0.99 mg/L / 72-h ErC50= 1.69 mg/L / 72 -h EyC50= 0.85 mg/L

Long term aquatic toxicity data are not available.

Additionally a ready biodegradability of Piperonyl butoxide (PBO) was estimated in a mineral test medium which was inoculated with micro-organisms from a municipal wastewater treatment plant. Piperonyl butoxide (PBO) cannot be considered as readily biodegradable under the conditions of the closed bottle test (degradation of Piperonyl butoxide after 28 days: -1.2%).
