Effects of micro/nanoplastics combined with three anthropogenic chemicals on larval zebrafish (Danio rerio): study of toxicity, behaviour and assessment of uptake

. Additionally, for all three chemicals, some plastic sizes decreased larval behaviour during the baseline or first light-dark period. Plastic particles did not modify the chemical uptake by the larvae. This suggests that enhanced toxicity caused by the plastics is not linked to changes in chemical uptake, metabolism, or excretion as hypothesized. Additional studies are necessary to better understand the role of plastic particles in a multiple stressor environment.
