How these trade-offs are resolved is inevitably shaped by  an increased emphasis on comparative exposure applying goals, principles, and decision rules defined assessment; in Step 2 -- aspects that are not scientific judgments.  increased use of physicochemical properties4 to The user should also describe the decision assess human health and ecotoxicity hazards; rules used to identify a "safer" alternative.

... Step 7 primarily focuses exposure (in the absence of exposure-mitigating on information about comparative exposure, human protection) between the chemical of concern and health, ecotoxicity, and physicochemical properties, alternatives be explicitly considered rather than with the goal of identifying alternatives that warrant assuming equivalent exposure.

... This effort is needed for two types of interrelated activities; first, to address how novel data streams could be used as primary data in human health and ecotoxicity hazard assessments (e.g., the use of in vitro mutagenicity data for DNA reactive chemicals) and second, to address how these data can be used to fill data gaps across a broad range of domains, including health, ecotoxicity, exposure assessment, and physicochemistry.
