A long-term test on aquatic invertebrates is proposed

Key value for chemical safety assessment

Additional information

According to claimed uses of 4-methylthiosemicarbazide aquatic compartment exposure is likely. At the moment no data is available for characterizing 4-methylthiosemicarbazide long-term effects on organisms inhabiting aquatic compartment. Risk assessment demonstrated that there is a risk for those organisms using the PNEC derived based upon acute data, that's why a long-term test on aquatic invertebrates is proposed in order to refine the PNEC value.
