文摘

P. subcapitata cultures were exposed to plastic nanoparticles in adsorption assays. UV/Vis and AFM showed ionic strength and surface chemistry influence adsorption of anionic and neutral nanoplastics. Growth inhibition of algae is antagonistically influenced by carboxylate-modified polystyrene and calcium. Physico-chemical characterization and proper dose metrics can be used to predict ecotoxicity.
