Additional information

Based on the test results, the substance could be considered as not highly adsorptive, that indicates that soil and sediment are not expected to be the main target compartments for exposure assessment.

When release in water compartment, the substance is not expected to be degraded. Indeed, the ready biodegradability study of 4-methylthiosemicarbazide has shown 0% of degradation at day 28. Furthermore, although the hydrolysis study did not show reliable results, one can considerer that the substance is hydrolytically stable with environmental condition (pH = 7).


However, due to a very low Log Kow value, the substance won't be bioaccumulable by aquatic organisms.
