Additional information

One key study of reliability 1 is available to assess the long-term toxicity of the active substance THPS to aquatic invertebrates. This study was performed on the THPS in solution in semi-static conditions, with the freshwater species Daphnia magna.

The result of this study is expressed in the table below (as main ingredient):
