Additional information

Three valid studies are available to assess the biodegradability potential of the substance. One study is assessed as the key study (Memmert, 2009) and the two others as the supporting studies (Zhang, 2010 and Clarke, 2011). According to these studies, the substance is neither considered readily nor inherently biodegradable. Therefore, the substance is considered persistent in the environment.
