文摘
- •
PS NPs caused no mortality in brine shrimp larvae (48 h) but sub-lethal effects were observed.
- •
PS-COOH NPs massively sequestered inside the gut lumen probably limiting food intake.
- •
PS-NH2 were adsorbed at the surface of sensorial antennulae and appendages.
- •
Multiple molting events during 48 h compared to controls were observed upon exposure to PS-NH2.
