Fig. 2From: Development and application of a health-based framework for informing regulatory action in relation to exposure of microplastic particles in California drinking waterSummary of the quality screening results for all in vivo mammalian studies against 26 criteria. Prioritized studies should be assigned a score of > 0 against all criteria. In this study, however, due to lack of data, a subset of criteria has been identified as necessary for results to potentially be considered as fit-for-purpose towards helping to inform a dose–response assessment (‘red criteria’); these criteria are displayed in red and indicated by an asterisk (*), with all other screening criteria shown in green. Additional details from the Tier 1 evaluation are reported in the supplemental information (reference figure/tables) and in Gouin et al., [42]Back to article page
