The bioactivity of white nurdles and burnt plastic collected eight months after the spill trended to lower values, and no additional end points were activated. On average, all end points in the TFand NR-FACTORIAL bioassays were below the 1.5-fold induction criteria for extracts from white nurdles collected eight months after the spill on January 17, 2022 (Table ). As for the burnt plastic, the induced average fold increase in activity trended lower; however, the activity of RXR was the only end point with a statistically significant reduction in activity (Figure , Table ).
