Plastic Nanoparticles Affect Behavior and Fat Metabolism in Fish (IMAGE)
Caption
This is a cartoon illustrating the test food chain with 24 nm polystyrene nanoparticles added at a concentration of 0.01 percent (w/v) to an algal culture, which after 24 h was filtered and fed to herbivorous zooplankton (algae from 250 ml culture given to 30 adult Daphnia). After another 24 h, the zooplankton were gently washed on a net in order to remove remaining or released free nanoparticles before zooplankton were presented to the top consumers of the food chain (fish; 4 individuals per replicate tank). The food chain was restarted every third day and the fish remained the same throughout the study. The control food chain was operated in the same way except that no nanoparticles were added. Each food chain started with 16 fish divided into four tanks. The number of fish in each tank decreased over time due to sacrifice of fish for sampling.
