Proposed sequence of events for implementing an exposure testing strategy aimed at grouping and modelling NMs. The research priorities are graded across the diagram, with hexagons to the left being of short term-priority (< 5 years) stretching to longer term priorities on the right (> 15 years). Grey hexagons represent modelling components that will lead to the ITS. The short-term priorities should be considered in the context of the long-term priorities to ensure that they generate the information needed to provide robust foundations for the longer-term priorities.
