Additional information
The influence of 4-methylpentan-2-one on the growth of the freshwater plant Lemna gibba was assessed in a semi-static limit-test in closed vessel design (OECD 221).
The 7-day ErC50was calculated to be > 146 mg test item/L for frond number and dry weight.
The 7-day EyC50was calculated to be > 146 mg test item/L for frond number and dry weight.
The 7-day NOErC and the LOErC were determined to be = 146 and > 146 mg test item/L, respectively.
The 7-day NOEyC and the LOEyC were determined to be = 146 and > 146 mg test item/L, respectively.Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
