The leaching of phthalates from PVC can be determined with an infinite sink approach.

ABSTRACT: Polyvinyl chloride (PVC) is the third most used polymer for plastic products in the European Union (+NO/ CH) and contains the highest amounts of additives, especially phthalic acid esters (phthalates). Leaching kinetics of additives from (micro-) plastics into aqueous environments are highly relevant for environmental risk assessment and modelling of the fluxes of plastics and its associated additives. Investigating the leaching of phthalates into aqueous environments in batch experiments is challenging due to their low solubility and high hydrophobicity and there are no standard methods to study release processes. Here we describe an infinite sink method to investigate the leaching of phthalates from PVC into the aqueous phase. Spiking and leaching experiments using bis(2-ethylhexyl) phth
