ECHA/NI/17/05

Key issues for assessing the complexity of read-across for multi-constituent and UVCB substances are addressed.

Helsinki, 7 March 2017 - A new document on using read-across for multi-constituent and UVCB (unknown or variable composition, complex reaction products or biological materials) substances describes key issues for assessing and addressing the complexity of read-across approaches for these substances. Furthermore, it contains example model cases to illustrate this complexity.
