Additional information

An algae growth inhibition study (Kelly, 1998) was conducted according to OECD 201 under GLP.

The test substance inhibited the growth of Selenastrum capricornutum, Strain No. CCAP 278/4 at concentrations tested in excess of 10 mg/L under the concentrations of this test. The EbC50(72h) was > 100 mg/L and the ErC50(0-72h) was > 100 mg/L.
