The ECHA/EFSA guidance for the identification of Endocrine Disruptors in the context of Regulations (EU) No 528/2012 and (EC) No 1107/2009 requires a highly complex and challenging assessment for all active substances. Ever since its publication in June 2018, implementing the requirements has been and will continue to be a challenge. With the proposed introduction of stricter regulation for EDs under the CLP and REACH Regulations, the challenge has recently been broadened. This conference will dive into the debate surrounding Endocrine Disruptors and covers all the relevant recent regulatory and scientific developments.
