E: Relevant target substances have a potential to be released (could not be eliminated by WWTP) and have (eco)toxicological substance properties of concern. Step 1: The aim of step 1 is to check if the substance has a potential to be released via WWTP into the environment by assessing the persistence and the mobility and taking into account expert judgement on the effect of end-of-pipe-measures on release minimisation. The result is the identification of target substances. Target substances do not necessarily fulfil the criteria for hazardous e.g. according to CLP regulation. As they have a potential to be released to the environment, they should be used with caution. Step 2: The aim of step 2 is to check if the substance has (eco)toxicological properties of concern. Scope: The two-step approach is valid for water soluble substances. Solid substances are out of scope of this interactive scheme. Volatile substances are out of scope of this interactive scheme.
