Description of key information

The 72h-EC50 of DMPT for algae is 1.5 mg/l, which indicates that the substance is moderately toxic to algae. 

Key value for chemical safety assessment

EC50 for freshwater algae:
1.5 mg/L
EC10 or NOEC for freshwater algae:
0.125 mg/L

Additional information

The non-GLP OECD 201 test was considered to be of sufficient quality and accuracy to assess the toxicity of DMPT to the green algae.
